2021-04-29 - Greene & Fogarty - Parna deposits in the Yass valleyRiverina Branch of the Australian Society of Soil Science
The document discusses parna deposits in the Yass Valley of New South Wales. Key points:
- Parna deposits in the area have properties comparable to deposits further west and impart favorable properties for agriculture, particularly wine grape production.
- Seven study sites were analyzed to characterize the morphology, distribution, and properties of the parna soils. Analytical tests showed the parna has stronger structure and fewer dispersive particles than underlying clay layers.
- The parna soils satisfy criteria for classification as high quality agricultural land due to their structural stability, available water capacity, and suitability for crops and pastures. However, current land mapping may underestimate the agricultural value of areas with parna soils.Payne developing criteria for soil health
The document discusses developing soil health interpretations from soil survey data. It explains that soil interpretations make soil data more useful by predicting soil behavior for different land uses. Developing interpretations involves defining the activity, identifying relevant soil properties and site features, assigning rating classes, and backing them with research. The document provides examples of interpretations for soil organic carbon storage potential, earthworm habitat suitability, and high tunnel suitability. It emphasizes that new interpretations can extend the use of existing soil data and help assess dynamic soil properties related to soil health.

SOM increased with 0.07% per Mg ha-1 of WB only immediately after application in the sandy soil, but in the clay soil, SOM increased around 0.25% per Mg ha-1 of WB during the third and fourth seasons. The effect of WB in increasing SOM in the clay soil was more significant in later seasons, raising questions about the mechanisms involved and whether other soil properties are affected.
Using soil data to inform soil health
This document discusses using soil survey data to inform soil health assessments. It provides an overview of soil properties that are relevant to soil health assessments, such as organic carbon, fertility, and soil biology. It also describes soil survey products like SSURGO and gSSURGO that provide soil data and properties. Tools for accessing and mapping soil data are presented. Steps for conducting on-farm soil health assessments are outlined. Methods for developing indices to evaluate soil properties and resilience are described, including examples of a soil suitability index and a fragile soil index. Applications of proximal sensing tools for measuring soil properties are briefly discussed.

Soil Classification
The Indian Standard Soil Classification System classifies soils into 18 groups based on particle size and composition. Soils are divided into three broad divisions: coarse-grained soils subdivided into 8 groups, fine-grained soils subdivided into 9 groups, and peat which is its own group. Coarse-grained soils are those where 50% or more of the material is retained on a 75 micrometer sieve. Fine-grained soils are those where more than 50% of the material passes a 75 micrometer sieve. The system further classifies soils based on gradation and the presence of silt or clay fines.

Geological controls on the reservoir petrophysical properties of “BETA Field” have been carried out using suites of wireline logs. Stratigraphic relationship among the reservoir sand bodies including their geometrical architectures, and their stacking patterns were also established. Exponential regression analysis of some of the petrophysical parameters were carried out to establish any relationship with depositional processes as well as depositional environments of the reservoir sand bodies in the field. The main factor controlling petrophysical properties and thickness for these reservoirs is the type of sandstone facies. The petrophysical evaluation of both reservoirs (K and Q) depicts porosity range from fair to very good across wells (i.e 11% to 25%). From the evaluated reservoirs porosity, there is no significant reduction of porosity with depth increase. The values obtained for the permeability of both reservoirs (K and Q) varied widely and inconsistent across the wells in the study field. The various depositional environments established in BETA field include fluvial, tidal channel, mouth bars, delta front, and the reservoir sands occurring in different depositional settings, resulting from different depositional processes, which had a wide range of petrophysical properties.

This document discusses a study that quantified the proportion of arbuscular mycorrhizal fungal colonization in the root systems of sea oats plants from dune systems on natural and renourished beaches on Bald Head Island, North Carolina. The study found no significant difference in the proportions of arbuscular, vesicular, or hyphal colonization between plants from renourished and natural dune systems. This suggests that nutrient availability and soil composition are similar between sites and that the successional age of vegetation is also similar. The findings provide insight into mycorrhizal associations and soil characteristics in renourished and natural dune systems.
THE KANAWA MEMBER, PINDIGA FORMATION
This project aims to study the clay mineralogy, provenance, paleoclimate, and paleoenvironment of the Kanawa Member of the Pindiga Formation in Nigeria. Samples will be collected from outcrops and analyzed using x-ray diffraction and fluorescence to identify clay minerals. This will help reconstruct the depositional environment and climate conditions during the time period. The study area is located in Ashaka quarry and along the Pindiga stream. Results are expected to provide information on sediment transport over time and paleoclimate.
Mediterranean landscapes characterization
ABSTRACT. The Mediterranean terraced landscapes are mainly shaped by agrarian drainage systems. They are nowadays increasingly exposed to degradation as a consequence of their changed management. The aim of this research is to characterize the slope lands drainage systems, at the landscape scale, in a hilly Mediterranean context, in order to define action priorities for their “active conservation, based on structural and agronomic parameters.
RÉSUMÉ. Les paysages méditerranéens de terrasse sont souvent façonnés par des systèmes de drainage agricole. Ils sont aujourd'hui fortement exposés à des dégradations du fait de changements et abandon progressifs de leur gestion. L'objectif de la recherche présentée est de caractériser les systèmes de drainage des terrains en pente à l'échelle d'un territoire dans des secteurs de collines méditerranéennes, pour aider à définir des priorités d'interventions agronomiques, environnementales et socio-économiques pour préserver ces systèmes de drainage. La zone d'étude comprend 6 200ha, principalement couverte d'oliveraies, et située sur le versant sud-ouest du Monte Pisano (près de Pise en Toscane). La méthodologie mobilise le SIG et les techniques de la télédétection ; elle conduit à la caractérisation du territoire en termes agronomiques et de structure physique. Ceci permet de dégager des orientations de gestion de ces territoires pour assurer le maintien de leurs fonctions agro-environnementales.

This study analyzed differences in soil pH and texture among four reforestation sites and two soil depths at Mount Cuba Center in Delaware. Soil samples were collected from each site and analyzed. The results showed significant differences in pH among sites and between depths, though texture did not differ. Ramsey sites had higher pH than Barley Mill sites. Both depth intervals differed in pH but could not be separated statistically. Soil textures included loam, silt loam and sandy loam, with each site containing a different combination. The study aims to identify soil characteristics that may influence tree growth to determine the best reforestation technique.

The QuantiSlake test is a new simple method to evaluate soil structural stability. It involves measuring the mass of a soil sample over time as it is immersed in water. Several indicators from the mass change curves are strongly correlated with soil organic carbon to clay ratio, which is a recognized proxy for soil structural stability. The test discriminates better than existing methods between different tillage treatments. It provides information on both slaking and clay dispersibility, and requires only basic equipment. The test represents a rapid and representative way to evaluate how agricultural practices and soil properties impact structural stability.

Soil quality parameters in ferralsols teixeira 2002
The document summarizes a study on the effects of different land use systems on soil quality parameters in a clayey Ferralsol in the Amazon Basin. Three key findings are:
1) Flocculation indexes indicate that most clay particles are flocculated across land use systems, maintaining the soil's structure.
2) Liming reduced aluminum levels and increased calcium, magnesium, and pH, causing temporary clay particle deflocculation near the soil surface.
3) Monitoring chemical parameters and flocculation indexes can indicate stability of the soil structure, an important factor for sustainable land use in clayey Ferralsols.

The document describes the establishment of a fine sequence stratigraphic framework for the Fuyu reservoir in the Zhou13 Block of the Zhaozhou Oilfield. First, a standard well, Zhou 801, was selected based on characteristics like complete formation, lack of faults, and clear stratigraphic cycles. Marker beds were identified from clear electrical properties. The reservoir was then divided into three groups (FI, FII, FIII) and seventeen small layers based on the marker beds and cycles in the standard well. Correlation was then performed between the standard well and other wells in the block to construct a unified stratigraphic framework.

1. Laterite samples were collected from western Burkina Faso and divided into three sub-samples that were prepared differently for gold analysis: sieved to <125 μm, crushed to <2 mm, and unprocessed.
2. Gold analysis showed that 67% of sieved samples had significant gold assays, while 25% of crushed samples and only 8% of both sieved and crushed samples from one location had similar gold levels. Unprocessed samples returned insignificant gold assays.
3. The study concluded that sieving laterite samples to <125 μm is the best preparation method for detecting concealed gold mineralization in lateritic terrains of savannah regions using geochemical exploration.

CLASSIFICATION OF SOIL
This document discusses the classification of soils. It describes the key horizons used to classify soils, including the O, A, E, B, C, and R horizons. The two main classification systems - the Unified Soil Classification System and the American Association of State Highway and Transportation Officials system - are explained. Both systems define grain sizes and use additional properties like color, texture, structure, density, water movement, acidity, and mineral reactivity to classify soils.

This document summarizes a study assessing the impacts of land management practices on soil and water quality parameters using data from the Water Resources and Erosion Watersheds Experiment research site. The study developed a web-based data system to analyze climate, soil, management, and other data from the site. Principal component analysis of soil properties at different depths found differences related to landscape position and land use, with tallgrass prairie soils generally having higher organic carbon and nitrogen than cropped soils. Future work will use near infrared spectroscopy to efficiently measure soil quality indicators.

This study evaluated the early impacts of conservation agriculture (CA) compared to conventional agriculture (CV) on farmer income, soil fertility, and microbiota in Laos. Results after 3 seasons showed:
1) Similar production costs and yields but higher net income for CA due to byproduct sales.
2) Soil structure stability and carbon/nitrogen levels decreased under CV, with losses of 4Mg C/ha and 0.5Mg N/ha, but no losses under CA.
3) Bacterial/fungal biomass and diversity trended lower under CV compared to native pasture or CA.
The study concluded CV had negative early agro-environmental impacts while CA maintained soil health and

It describes the key aspects of each system such as group name designations, plasticity characteristics, grain size thresholds. Examples are provided to demonstrate how to classify soils according to their particle sizes, plasticity properties and assign them the appropriate group symbol under different systems.
Reservoir Characterization of “G900” Sandstones Using Wireline Logs and Cores...
Wireline logs and cores are analysed to evaluate the quality of reservoir “G900” of Gabo field as
insight for reservoir production optimization planning. “G900” have very good intergranular porosity and
excellent permeability with the main reservoir fluid content as oil and water. “G900” sands are cleaner
towards the North indicating relatively higher play potential. This clay rich subarkosic to arkosic sandstones is
rich in quartz and albite with grain size that is fine to coarse, dominantly poorly sorted, platykurtic to
mesokurtic with symmetrical to fine skewness.. It is a stacked interval of near shore deposits within deltaic
sequences that is rich in ripples and cross stratifications. Effective reservoir development plan of “G900” is
achieved by combining this result with seismic, well test, production data and other geological information to
reduce uncertainties, reveal “G900” lateral extent, compartmentalization, complexities, and fluid quantity for
improved production forecast.
adaptiations and validations of slope mass rating
This document discusses several methods for rating rock slope stability: the Chinese Slope Mass Rating (CSMR), Fuzzy Slope Mass Rating (FSMR), Modified Slope Mass Rating (M-SMR), Rock Hazards Rating System (RHRS), and SMR-Tool. It provides details on how FSMR applies fuzzy set theory to the SMR system and how M-SMR modifies SMR's parameter calculations. Finally, it mentions how RHRS was developed for assessing rockfall risk along roads and how SMR has been incorporated into hazards evaluations.

45038163 geological-map-interpretation
Geological map interpretation involves analyzing outcrop patterns to understand the underlying geology. Horizontal beds follow contours, while dipping beds cut across contours in curved patterns. The direction of dip can be determined using the V-in-valley rule. Younger rocks come to the surface in the direction of dip. Structures like faults and folds are identified by offsets and bends in outcrop patterns. Cross-sections are constructed by projecting geological boundaries and topography from the map onto a profile of the same scale.

well logging tools and exercise_dileep p allavarapu
Logging is a process that provides comprehensive formation information through continuously recording parameter measurements with depth. It plays an important role in exploration and production by obtaining resistivity, porosity, and lithology logs to identify hydrocarbon-bearing zones. Different disciplines like drilling, logging, core analysis, and reservoir modeling are interrelated and provide both open and cased hole data. Logs are interpreted to calculate parameters like water saturation, hydrocarbon saturation, and effective porosity, with the goal of determining hydrocarbon saturation multiplied by effective porosity in reservoir units. Accurate interpretation requires integration of log data with core analysis and rock physics studies.
formation evaluation chapter 1
Formation evaluation and well logging are processes used to determine the properties of subsurface reservoirs and identify commercially viable oil and gas fields. Key logging tools developed over time include resistivity logs in the 1920s, dipmeters in the 1940s, gamma ray and neutron logs in the 1940s, sonic logs in the 1950s, density logs in the 1960s, and logging while drilling was introduced, allowing real-time data acquisition. The document provides a historical overview of the development of various openhole well logging tools and techniques.
Basic well log interpretation
This document provides an overview of well log interpretation. It discusses how well logs are used to answer key questions about hydrocarbon-bearing formations like location, quantity, and producibility. The interpretation process involves identifying permeable zones using logs like SP and GR, then using resistivity and porosity logs to locate zones with hydrocarbons. Formations are further evaluated to determine porosity, fluid saturations, and other properties through techniques like density-neutron crossplots, environmental corrections, and determining formation temperature based on geothermal gradient. The goal is to locate potential producing zones and estimate hydrocarbon quantities and recoverability.
Formation evaluation and well log correlation
This document provides an overview of well log formation evaluation and interpretation. It discusses the basic well log tools used to measure parameters like gamma ray, resistivity, density, and neutron porosity. It describes qualitative log interpretation to identify reservoir zones, hydrocarbon-bearing zones, and fluid types. The document also covers quantitative interpretation, including calculating porosity, water saturation, and estimating hydrocarbon reserves. In conclusion, well logs provide key information for establishing the existence of producible oil and gas reservoirs, including reservoir type, thickness, porosity, permeability, and fluid saturation.

This study examined the effects of sulfur amendment on soil pH and nutrient availability in organic soils with varying levels of calcium carbonates in the Everglades Agricultural Area of Florida. The study included four rates of elemental sulfur (0, 90, 224, 448 kg/ha) and three levels of added calcium carbonate (0%, 12.5%, 50% by volume) in a greenhouse pot experiment with sugarcane. The results showed that sulfur amendment had little effect on soil pH across all calcium carbonate levels due to the strong buffering capacity of the soils. Higher calcium carbonate levels significantly increased soil pH. While sulfur increased sulfate levels in the soil, it did not enhance other nutrient availability, possibly due to the inabilityCHAPTER5.DOC
This study evaluated changes in soil acidity and basic cations under pine plantations of different ages in South Africa. The main finding was a decrease in soil solution ionic strength with increasing plantation age. A strong decline in basic cations and increase in acidity occurred in the first two decades following afforestation. The ratios of basic cations to acidity on exchange sites and of Ca to Al in soil solutions fell below critical levels in some plantations, indicating potential future forest productivity problems. Further research on changes in the first 20 years and between soil horizons was recommended, as well as studying the effects of tree species and physical soil properties.

Biologia, 2019
The relationship between the size of the particle fractions of the soil substrate and the diversity of the spontaneously developing vegetation was investigated on coal mine spoil heaps in Upper Silesia (Southern Poland). The analyses were based on 2567 research plots of developed spontaneous vegetation and their associated soil substrate samples collected from 112 coal mine spoil heaps. For each research plot the prevailing particle size fraction was determined (stones, gravel, sand, silt), the species composition and abundance was recorded and the species richness (S), Shannon-Wiener diversity index (H′), Simpson (C) and Evenness (E) indices were used to determine species diversity. From a total of 119 research plots (in all particle size fraction categories), the values of 15 physicochemical properties (pH, electrical conductivity, water holding capacity, moisture, carbon content, total N, available P, Mg and exchange cations Ca, Mg, K, Na, fine particles (%), gravel (%), stone (%)) were obtained to asses their impact on the floristic composition of vegetation patches using Canonical Correspondence Analysis (CCA). Additionally, functional traits of the dominant species of each vegetation patch (life forms, life strategies and socio-ecological groups), were selected to analyse their relation to substrate texture. It was shown that the highest species richness and the highest values for Shannon-Wiener diversity index, as well as Simpson and Evenness indices, were obtained in plots formed on stones. Moreover, the greatest variation in the participation of species representing different habitats, life forms, and life strategies was found on gravelly substrates. Contrary to our expectations, the vegetation diversity (in terms of both species and their functional traits) was not highest in habitats with a high composition of fine size particles.

The integrated study characterized the reservoir quality and stratigraphy of the Mowry Shale and Muddy Sandstone in the Powder River Basin. Five depositional facies were identified in the Muddy Sandstone based on core and well log analysis, with the cleanest reservoir sands found in tidal inlet and channel deposits. The overlying Mowry Shale consisted of three parasequences deposited in a restricted shelf environment. Seismic inversion and lithofacies modeling were used to map the facies distributions across the 3D seismic volume. The results provide insights into the stratigraphic framework and reservoir characteristics of the two plays to better assess their exploration potential.

This study examined how fish farming activities affect the biological and geochemical properties of muddy and sandy sediments in the Mediterranean Sea. Samples were collected from sites near four fish farms and analyzed for total organic carbon, total organic nitrogen, oxygen consumption, phosphate release, and benthic diversity. Results showed that samples from silty sediments near fish farms had higher levels of organic carbon and nitrogen, higher oxygen consumption, higher phosphate release, and lower benthic diversity compared to reference sites. Muddy sites were more significantly impacted than coarse sediment sites. The study suggests that organic enrichment from fish farming affects muddy and sandy sediments differently due to their distinct biogeochemical characteristics.

Heavy metals and acid rain were applied over 4 years to a model forest ecosystem to study their effects on soil microbial communities. Microbial biomass, basal respiration, and hydrolase enzyme activities were reduced by heavy metal contamination, especially in combination with acid rain. Analysis of phospholipid fatty acids and genetic fingerprints showed that heavy metals altered the structure of bacterial communities over time. While soil pH and available heavy metal levels were similar between treatments with just heavy metals and those with both heavy metals and acid rain, the combined treatment had more drastic negative effects on the microbial community. This suggests that acid rain exacerbates the toxicity of heavy metals to soil microorganisms.
About the Interaction between water and Pb, Zn, Cu, Cd, Fe, Mn, Ba Mineralize...
ABSTRACT: One of the most important environmental concerns at mining sites is acid mine drainage (DAM), which is formed by the exposure sulfide minerals to air and water. The consequent production of sulfuric acid reduces the quality of water bodies and may allow the solubilization of potentially toxic metals such as Pb, Zn, Cu, Cd, Fe, Mn and Al. There is a range of laboratory procedures, classified as static and kinetic. Which have been used to understand the acidification and neutralization potencies of a rock through water/rock interaction process. These procedures seek to describe, quantify and predict the compositional changes of the solid and liquid phases in natural systems. The choice of techniques, methods, procedures and protocols requires the understanding of the problem to be solved or mitigated and is related to the specific geochemical and geological characteristics of the site to be analyzed. The elaboration of experimental procedures involves sampling strategies, selection of methodologies, (Accuracy, precision, sensitivity, speed, cost) and thus equipment and other necessary materials. This work presents the main static and kinetic procedures, highlighting its principles, advantages and limitations for selection and application in carbonate rocks rich in sulphide minerals. PH, Acid-Base Accounting and Net Acid Generation (NAG) are the static methods chosen. While the kinetic procedures chosen for the study of the natural enrichment of toxic metals in sulfate carbonate rocks is leaching columns, the Soxhlet system and reaction reactors. To provide more consistent drainage forecasts and hence better plans for the management of The results of different methods should be analyzed together.
Mobility of Trace Elements in Virgin Soils from the Bobov dol Valley, Bulgaria
The document analyzes the mobility of trace elements like copper, zinc, lead and manganese in virgin soils located near the Bobovdol Thermoelectric Power Plant in Bulgaria. Four soil profiles were studied using classical soil sampling and analysis methods. The results show that the total content of trace elements in the soils is lower than background levels and within non-toxic ranges. Organic and mineral colloids like silt and clay fractions were found to be the main collectors of mobile metal species. The mobility of zinc and manganese seemed most associated with pedogenesis near the soil surface, while copper mobility was strongly influenced by soil organic carbon and pH levels. Lead mobility was less dependent on soil forming processes and more influenced by its total content across
M Stone- Dissertation Defense
The document summarizes research from a dissertation on microbial contributions to carbon and nutrient cycling across tropical landscapes. It finds that:
1) Soil carbon and nutrients decline rapidly with depth, while microbial biomass and activity also decline but metabolic activity per unit biomass remains similar or increases in deeper soils.
2) Soil organic matter chemistry differs between forest types near the surface but not with soil type, and alkyl carbon may be important for long-term tropical carbon storage.
3) Specific phosphatase enzyme activity is higher in deeper soils, suggesting microbes invest more in phosphorus acquisition under resource-limited conditions.

This study examines the petrophysical properties and lithofacies distribution of the upper Miocene Abu Madi Formation, a major natural gas reservoir in the Nile Delta. Six lithofacies were identified from core analysis, including trough cross-bedded, parallel laminated and massive sandstones that serve as the primary reservoirs. The sandstones exhibit good porosity but variable permeability, with the trough cross-bedded and massive lithofacies having the best reservoir quality. Clay and silt-dominated lithofacies act as vertical permeability barriers. The depositional environment was interpreted as fluvial channels within incised valley-fills. The study provides insights into reservoir quality and exploration of fluvial channel deposits

Taking all these into account, it is important to increase the fertility of the soil from the erosion process in Ismayilli and to prevent the washing of fodder crops from perennial herbs. The cultivation of these plants in the mountainous regions protects the slopes from the terrible erosion process and provides the animals with a strong fodder. It is proved by the results of the research that restoration of fertility and ecological balance of erosion lands and the implementation of soil-agro-technical measures to increase productivity are of great importance. Due to the application of these measures, I, as a result of improving the water and physical properties of the affected land, prevent surface water flows. In addition, the results of the study have been proven by the fact that, for certain reason, erosion and erosion hazards are most likely to be taken over by the sowing of perennial herbs. Thus, perennial herbs, in particular, accumulate the nitrogen atmosphere of the legumes, enriches the soil with organic matter, accelerates the formation of water-resistant granular - topical structure and improves its water-physical properties, which in turn facilitates the rapid digestion of foodstuffs.Biomasa microbiana del suelo un factor clave del suelo.pdf
This document discusses soil microbial biomass as a key driver of ecosystem functioning. It makes three main points:
1. Soil microbial biomass plays a key role in ecosystem sustainability by maintaining essential soil functions and nutrient cycling. Larger microbial biomass results in higher ecosystem stability and ability to withstand disturbances.
2. Environmental drivers like climate, soil properties, vegetation composition, and land use influence patterns of microbial biomass across different ecosystem types. Nutrient-poor ecosystems rely more on microbial biomass as a nutrient reservoir.
3. Restoring degraded lands requires considering microbial activities and biomass development in response to environmental drivers. Mixed plantations can help recover lost microbial diversity and biomass faster than monocult

The study was conducted in Vom, Jos Plateau state in the Southern Guinea Savanna zone of Nigeria to accentuate the forms of potassium distribution associated with topographic positions. The study area lies between longitudes 080 45’ 01” and 80 47’ 56’’ E, latitudes 90 43’ 17’’ and 90 45’ 15’’ N, with an elevation of about 1270m above sea level. A stratified purposive sampling procedure was adapted, where four landscape positions were identified using Global Positioning System (GPS). The crest, upper slope, middle, and lower slope positions were identified, each representing changes in geomorphology. Two pedons were georeferenced at each topographic position, where they were sunk and described. Result show that the forms of K varied with topographic positions. Potassium distribution varied from surface to subsurface in different topographic positions. Water soluble K was higher at crest surface (0.0569 cmolkg-1) and decreased with soil profile depth. Exchangeable K has highest value of 0.1317 and 0.1308 cmol/kg-1 at both lower slope positions in general. Non exchangeable K values where higher at all surfaces than the subsurfaces of topographic positions. HCl soluble K values were higher at lower and upper slopes surface, moderately at middle and least at crest slope positions. Total K values were higher at upper slope subsurface, middle, and lower slope surface with low variations at the crest positions. However, the distribution of the K forms did not shown a well – defined trend with respect to topographic positions.
Composition of soil and earth crust
This document discusses the composition and properties of soil. It describes soil as having three phases: solid, liquid, and gas. The solid phase contains minerals like quartz and clay minerals. Clay minerals are important due to their large surface area and ability to adsorb ions. The liquid phase is the soil solution and contains dissolved organic and inorganic components. The gas phase in soil contains lower oxygen and higher carbon dioxide than the atmosphere due to plant and microbial respiration. Organic matter in soil originates from plants and microbes and influences soil properties. Phyllosilicate clay minerals are described as having a permanent negative charge that influences cation retention and swelling behavior.
An Example Emphasizing Mass Volume Relationships For Problem Solving In Soils
1) The document describes a method for estimating the amount of subsidence (reduction in thickness) that occurred in an organic wetland soil after it was drained.
2) Subsidence occurs through two processes: primary subsidence due to loss of buoyancy and shrinkage when water is removed, and secondary subsidence from oxidation of organic matter when the soil becomes aerobic.
3) To estimate the original thickness, assumptions are made that the mineral fraction and sand content remained unchanged during subsidence, and properties of the undrained soil can represent the drained soil before subsidence. Data on thickness, bulk density, and sand content from the drained and undrained soils are then used in calculations.
Characterization of soils at angacha district in southern ethiopia
The document summarizes a study characterizing soils at Angacha Research Station in Ethiopia. Soil samples were collected from horizons in a soil pit and analyzed in the lab. The soil was found to be an Alfisol with a clay loam texture. It has good fertility with medium organic carbon content that decreases with depth. The soil has properties making it well suited for agriculture, including a subsurface clay accumulation and base saturation over 35%. Soil management should focus on maintaining organic carbon and nitrogen levels.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

The use of Geological information for soil mapping, Raimonda Kasparinskis, Faculty of Geography and Earth Sciences, University of Latvia
- 1. Raimonds Kasparinskis Faculty of Geography and Earth Sciences, University of Latvia THE USE OF GEOLOGICAL INFORMATION FOR SOIL MAPPING
- 2. Problems of soil mapping in boreal-nemoral zone High spatial diversity of soil cover (according to genetic classification and FAO WRB classification); Deficiency of information about the genetic origin of geological deposits and forming time influence on soil distribution
- 3. Solutions / Hypothesis Soil diversity and its physical and chemical properties in boreal-nemoral zone are dependent mainly on soil texture, that is determined by the genetic origin of geological deposits and forming time. These factors impacts also forest stands distribution and development, which, conversely influences topsoil properties.
- 4. The Aim Clarify the opportunities of the application of geological information for soil mapping according to FAO WRB classification in boreal-nemoral zone
- 5. Objectives of the study What are the relationships of the spatial distribution in boreal-nemoral zone? Soil groups and prefix qualifiers (FAO WRB); Properties (physical, chemical) Quaternary deposits; Properties (physical, chemical) ?
- 6. Raw data In Latvia, from 2006 till 2010, under the international project „Inventarization of forest soils and assessment of forest biological diversity „BioSoil”” of the Focus Forest research programme (No.2152/2003) of the International Co-operative Programme (ICP) and the Europe first level forest monitoring, investigations were carried out on 95 sampling sites of ICP Forest monitoring and in 18 sampling sites within relatively poorly represented regions of this monitoring in 2011.
- 7. The research of soil distribution
- 9. The Results of Generalized Linear Models EOLIAN sediments BALTIC ICE LAKE sediments GLACIO- LACUSTRINE deposits GLACI- GENIC deposits ORGANIC deposits GLACIO- FLUVIAL deposits Statistically significant correlations (the level of significance p<0.005)
- 10. The Results of Generalized Linear Models The use of prefix qualifiers of soil groups (Example of Arenosols) Albic RubicFerralicEndogleyic Hypoferralic EOLIAN sediments BALTIC ICE LAKE sediments GLACIOLACUSTRINE deposits GLACIOFLUVIAL deposits Statistically significant correlations (the level of significance p<0.005)
- 11. The Results of Generalized Linear Models The use of prefix qualifiers of soil groups (Example of Podzols) AlbicHistic Endogleyic EOLIAN sediments BALTIC ICE LAKE sediments GLACIOLACUSTRINE deposits GLACIOFLUVIAL deposits Statistically significant correlations (the level of significance p<0.005)
- 12. The Results of physical and chemical properties in Principal Component Analysis (mineral soil 0-10 cm depth)
- 13. The Results of physical and chemical properties in Principal Component Analysis (mineral soil 0-10 cm depth)
- 14. The Results of physical and chemical properties in Principal Component Analysis (mineral soil 40-80 cm depth)
- 15. The Results of physical and chemical properties in Principal Component Analysis (mineral soil 40-80 cm depth)
- 16. Conclusions / Solutions Quaternary deposits and their composition is one of the main factors, determining the spatial distribution of soil groups (FAO WRB) and physical and chemical properties. The usage of the prefix qualifier of soil groups in data processing enabled us to define more precisely the significant relationships between some particular distribution of Quaternary deposits and soils.
- 17. Conclusions / Solutions Determining the existing relationships facilitates the future mapping of the boreo-nemorial region soils that have formed mainly on the Late Weichselian Glacial deposits, altered by postglacial aeolian, marine, lacustrine, alluvial and mire sediments on a regional scale of 1:50000. Taking geological contours as a basis, it is possible to single out soil group associations in soil mapping, although it is difficult to single out separate soil groups.
- 18. Conclusions / Solutions In perspective, it would be necessary to continue studies, clarifying the strengths and weaknesses of the FAO WRB soil classification and its application in the research of boreal-nemoral forest zone.
