This academic article summarizes a study on the depletion of soil nutrients in agricultural land over time. The study analyzed soil samples from different arable areas in Bhopal, India twice over a one year period. The initial samples had higher concentrations of most nutrients measured compared to the later samples, indicating depletion occurred. Factors like soil pH, erosion, temperature fluctuations, and lack of organic carbon management can limit nutrient uptake by plants and availability over time. Integrated plant nutrient management that uses fertilizers, manures, and agronomic practices is recommended to sustain agricultural productivity and food supply.
Influence of Arbuscular Mycorrhizal Fungi, Green Manure of Leucaena leucoceph...BRNSS Publication Hub
White yam (Dioscorea rotundata) was planted in the abandoned quarry to determine the growth and yield effects of mycorrhizal fungi, green manure, and other soil amendments. Seed yams were planted on the heaps (1 m × 1 m) in three replicates and three blocks. Data collected were analyzed using analysis of variance and Duncan multiple range test. The results showed that Glomus mosseae, Glomus etunicatum, green manure of Gliricidia sepium (GS), poultry manure, and NPK fertilizer influence yam’s shoot, root, and tuber weights. It was further observed that the combined treatments of GS and Leucaena leucocephala had better enhancement of growth and yield characters of yam. Biofertilizers together with plant and animal remains are therefore recommended for the bioremediation of quarry and other areas affected by natural, human, or ecological activities.

Nutrient budgets are becoming accepted tools to describe nutrient flows within cropping system and to assist in the planning of the rotational cropping and mixed farming system
Depending on the farm management and the balance of inputs and outputs of nutrient N,P and K budgets have been shown to range from deficit to surplus in cropping system
Budgets are the outcome of simple nutrient accounting process which details all the inputs and outputs to a given defined system over fixed period of time
A soil surface nutrient budget accounts for all nutrients that enter the soil surface and leave the soil through crop uptake.
Soil is precious natural resource equally as important as water and air. The proper use of soil greatly determines the capability of a life-support system.The agriculture era has been changed from resource degrading to resource conserving technologies and practices which will enable help for increasing crop productivity besides maintaining soil health for future generations. Green revolution besides achieving food security, imposes several threats like deterioration of the soil organic carbon stock, decreasing factor productivity, imbalances in NPK and micronutrient use and disparity in fertilizer consumptions etc.
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.

Integrated Nutrient Management refers to the maintenance of soil fertility and of plant nutrient supply at an optimum level for sustaining the desired productivity through optimization of the benefits from all possible sources of organic, inorganic and biological components in an integrated manner
Integrated nutrient management (INM) involves efficient and judicious use of all the major components of plant nutrient sources for sustaining soil fertility, health and productivity
Integrated approach for plant nutrition is being advocated because single nutrient approach often reduces fertilizer use efficiency and consequently creates problem fertilizers can help in enhancing and maintaining stability in production with least degradation in chemical and physical properties of the soil.
A healthy soil is a living, dynamic ecosystem that performs many vital functions.
A healthy soil produces a healthy feed for consumption. Improved soil health often is indicated by improvement on physical, chemical and microbiological environment.
Introduction of high yielding varieties, irrigation and use of high analysis fertilizer without proper soil tests, accelerated the mining of native soil nutrient resources.
Under intensive cultivation without giving due consideration to nutrient requirement has resulted in decline in soil fertility and consequent productivity of crops

Studies on the impact of crude oil exploration on soil quality and crops grow...Premier Publishers
The present study evaluated the impact of crude oil exploration on soil quality and crops grown in Kpean Community in Khana Local Government Area of Rivers State. Soil samples were collected at a depth of 0-50cm3 using plastic auger while tuber crops and vegetables were harvested from the same spot as the soils. Findings from this study showed an increase in soil temperature, moisture, electrical conductivity and organic matter content of crude oil impacted soil compared to control (P<0.05).soil><0.05).><0.05)><0.05). The results of this study indicates that crude oil pollution of agricultural farmlands in Kpean Community is yet to be remedied even after 20 years following oil spillage and the soil still remain unsuitable for crop production. Hence, proper remediation of the studied area is paramount in order to reduce metal accumulation and subsequent exposure of the populace to metal poisoning via food chain.
Does fertilization practices increase residual nitrate nitrogen in soil irrig...IJEAB
Treated wastewater has significantly improved DM yield compared to ground water. The form of nitrogen provided by the water was determinant in drawing yields. Irrigation with ground water (where nitrogen is as nitrate) induces a faster migration of nitrogen at depth. In contrast, using treated wastewater (where nitrogen is as ammonium), resulting in a relative distribution of the remaining nitric smaller in the lower profile and therefore higher in the surface, especially after the second year (2010). In addition, the relative distribution of nitrates in the soil surface is even more important in the presence of organic manure. All happens as if a certain amount of ammonium provided by treated wastewater is retained in the organic compounds of manure. Yields were significantly lower in irrigation with treated wastewater in the second year and especially when fertilization was given in additional. If the soil can be used for storage of the nitrogen supplied by the treated wastewater during the first year of irrigation (24 kg N-NO3/ha before irrigation to 115 kg N-NO3/ha after irrigation), to the second year the capacity drops (to 64 N-NO3/ha) and a significant increase in nitrate leaching occurs. Therefore, unlike the contribution of manure that seems enrich the topsoil nitrate nitrogen, at least during the first campaign, mineral fertilization unreasoning causes faster migration of nitrogen at depth.
Indian agriculture feels the pain of fatigue of green revolution.
In the past 50 years, the fertilizer consumption exponentially increased from 0.5 (1960’s) to 24 million tonnes (2013) that commensurate with four-fold increase in food grain output (254 million tonnes) In order to achieve a target of 300 million tonnes of food grains and to feed the burgeoning population of 1.4 billion in 2025, the country will require 45 million tonnes of nutrients as against a current consumption level of 23 million tonnes. The sustainable agriculture and precision farming both are the urgent issues and hence the suitable agro-technological interventions are essential (e.g., nano and biotechnology) for ensuring the safety and sustainability of relevant production system.

Assessment of Zinc and Copper Status of Fadama Soils In Borgu Local Governmen...Agriculture Journal IJOEAR
Abstract— The status of Zinc (Zn) and Copper (Cu) of fadama soils under cultivation at Borgu Local Government Area, Niger State, Nigeria was studied. Soil samples were purposely collected from three extension blocks, namely; Wawa, Babana and Goffanti. Particle size distribution of the soils showed sandy loam texture. The soils pH were either slightly acidic or neutral with a range between 6.05 and 6.93. The level of Organic Carbon (OC) ranged between low and medium, total nitrogen were rated high, available phosphorus were low while exchangeable cations (Na, K, Ca, Mg) were all rated high. Though soil content of Zn and Cu were very low, values were not significantly (P<0.05) different for all locations. The mean values for Zn ranged between 0.496 and 0.592 mg/kg, while Cu ranged between 0.550 and 0.945 mg/kg. This result implies that soil amendments in the form of organic manure and/or supplement of Zn and Cu would enhance nutrient availability for optimum yields of crops for the resource-poor farmers in the study area.
Phosphorus mineralization of bioslurry and other manures in soil Premier Publishers
The experiment was conducted to see the phosphorus (P) mineralization pattern of bioslurry under aerobic and anaerobic soil conditions. Two bioslurry (cowdung bioslurry and poultry manure bioslurry) and their original manure (cowdung and poultry manure) at 3, 5, 10 and 20 t ha-1, respectively were thoroughly mixed with soil and incubated in aerobic and anaerobic moisture condition for 12 weeks. Among the four different types of manure, P release from poultry manure slurry was the highest. Poultry manure and cowdung slurry recorded very closer amount of available P. Both cowdung slurry and poultry manure slurry released higher amount of P compared to their original state (cowdung and poultry manure). P mineralization reaches in peak within 4-6 weeks of incubation. Under anaerobic condition the P mineralization was found higher compared to aerobic condition. The P mineralization data fitted strongly to the first order kinetic model. The bioslurries had lower rate of mineralization but had higher potentiality to release P in the soil compared to their original state.

Abstract— Soil where shooting practices are conducted is extremely contaminated with heavy metals, exclusively by Pb, due to the bullets and bullet fragments. These extreme concentrations of Pb, generate an unfavourable surroundings for agriculture and human health through phytoaccumulation. This study was conducted to assess the possibility of particular bio-amendment, phytostabilization on the reduction of bioavailable Pb in such contaminated soil. Biomass (BM) produced from Gliricidiasepium was used to see its ability to be used in soil remediation together with Maize (Zea mays) as phytostabilizer. A pot experiment was conducted with Maizeby adding BM at three different percentages, 1, 2.5 and 5% (w/w). Soil without amendments served as the control and arranged in a complete randomized design. By maize, translocation rate of heavy metals into crop were determined. After sixth week, grown maize were harvested and analyzed followed by digestion with con.HNO3. The most significant immobilization (p<0.05)>TF in maize. For the treatment 5% BM, PF and TF for Pb are 1.22 and 0.15 respectively. Thereby maize can be considered as a potential phytostabilizer. At the same time efficiency of phytostabilizing nature of maizecan increase together with the application of soil amendment – BM.

Enhancing Productivity and Livelihoods among Smallholders Irrigations through...Jenkins Macedo
This field research was presented at the 2015 3rd Global Conference on Climate-Smart Agriculture in Montpelier, France on March 18, 2015.
Climate change and climate variability pose significant risks to smallholders in the rainfed lowlands of Lao PDR. Increased surface temperatures, declining rainfall, persistent drought and depletion of soil nutrients all serve to impact agricultural productivity and livelihoods. This study investigates the impact of five treatments on soil nutrients, moisture, plant growth, and yield of water spinach (Ipomoea aquatica). The treatments tested were rice husk biochar only, biochar inoculated with manure, manure tea, inorganic fertilizer and the control. The costs and benefits of the treatments were also assessed. The randomized complete block design was used to assign five treatments and eight replications to the experimental units. Biochar was produced through slow pyrolysis. Soil physical properties were assessed with the visual soil assessment method and 15-randomized soil samples were collected for chemical analyses. Sprinklers were used for irrigation and a weather station installed to monitor the climate. Descriptive statistics and analysis of variance were used to analyze the data. Costs-benefits evaluation of the treatments was conducted to determine the net benefits relative to the initial costs ratio. The analysis of variance of mean yield indicates that the difference in yield among the treatments was highly significant. The computed F value (8.28) was higher than the F critical (2.64) at the 5% level of significance. The calculated coefficient of variance of mean yield was 17.33%. The net benefits to initial costs ratio of treatments suggest that the control (4.11), biochar inoculated with manure plus NPK (1.64), and biochar plus manure tea (1.01) are preferred. The net benefits and initial costs evaluation of treatments is important to assess whether utilizing these treatments would impact smallholders’ livelihoods. The results of this study contribute to the evidence that biochar could play an essential role to mitigate climate change risks by enhancing soil quality and increase agricultural productivity.
An efficient incentive of Nitrate and Fluoride on Organic highland cropping s...IOSR Journals
Abstract: Exerting necessitated concentrations of Nitrate and fluoride to the organic highland cropping
systems is a vital management technique. All the chemical elements of the earth’s crust occur in widely differing
omnipresent concentrations, due to their different nuclear chemical formation and geochemical history. The use
of biological nitrogen and fluoride inputs complicates its balancing act due to dandier uncertainty in inorganic
Nitrogen and Fluoride availability. The growers to strike maintain Nitrogen provisioning to support crop
growth and retention of limit pollution followed by fluoride associated soils. Due to various activities of the man
in domestic field, agriculture area and industrial establishment the environment around us consisting soil, water
and air gets polluted. Fluoride inexhaustible concentrations forbid the growth of crop even though nitrates
reposit in the cultivated soils. The purpose of this project was to establish kinetics when nitro fluorides
associated in the highland soils to different crop systems towards environmental pollutions. Cordia Africana
and alfalfa are the plants which make soil to get enrichment of Nitrates and deescalate of concentrations of
fluorides from cultivated soils through its decomposition. This entire study went on its conventionally tilled
crops followed by Cordia Africana and alfalfa stems and leaf particles. Surface soil nitrate concentrations were
measured weekly, biweekly by volumetric analysis and nitrate leaching was estimated from tension Lysimeters
which were buried at the soil bedrock interface. Subsequently by using Orion 720A fluoride ion meter, deescalated
concentrations of fluorides have been measured. The demonstrated concentrations of Soil in NO3
variables, coefficients of variations from the mean concentrations across all samplings have been recorded
sporadically. The total area of the soil bed was maintained the same PH values until project was completed by
weigh Lysimeters. The timing of elevated Nitrate concentrations (10-15PPM) and the concentrations of fluoride
in deeper soil water corresponds with fallow periods. These dynamics will assist growers in adapting the timing
management operations and reduces nitrate departures.
Variability of some physicochemical properties on Lithosequence in Funtua, Northwestern, Nigeria were studied to determine the extent of variation in physical and chemical properties within and between soils developed on basement complexes, loess over basement complexes and loess parent materials. Variability was more pronounced in chemical than in physical properties. Particle density (CV = 0.23%) and exchangeable sodium percentage (CV = 2.23) were the least variable physicochemical properties. Physicochemical properties with highest variability are Si/C ratio (CV =88.29%) and AP (CV = 149%). Less variability (CV ≤ 15%) irrespective of soils were recorded in particle density, bulk density and pH, and therefore required similar management for all the soils. Silt, AWHC, CEC, CEC clay and base saturation were consistently moderately variable (CV: >15 ≤ 35%). Silt/clay ratio, K, OC, TN, AP and AS were consistently highly variable CV > 35%). Large proportion of properties of the soils were highly variable in all the soils with 10 (42%) of physicochemical properties of soils on BC, 9 (38%) on LBC and 13 (54%) on LS. The highly variable status was attributed to difference in land use types, management and cultural practices occurring within the study area. Properties significantly influenced by Lithosequence include available water holding capacity, magnesium, potassium, CEC and TEA. They were significantly highest in soils on loess and contributed to variation in pattern of nutrient and exchangeable bases retention.

Abstract— The aim of the studies was to determine suitability of effluent from methane digestion of organic wastes generated during processing of sugar beets for soil application at sugar beet plantations. In the paper parameters of technological value of sugar beet roots harvested from plots with standard values (i.e. optimal values for processing) which were defined by the Institute are discussed. It was shown that effluent from digestion of sugar beet pulp can be utilized as soil amendment on sugar beet plantations without any restrictions bearing in mind content of heavy metals and harmful microorganisms. Nutrients contained in studied effluent from gasifier are available for sugar beet plants at the same level as nutrients from mineral fertilizers. Determination of heavy metals in soil samples taken before and after effluent application did not reveal accumulation of harmful elements in the soil in the result of waste utilization.

Four types of compost (prepared with 0, 5, 10 and 15% of wood ash prior composting) were used to amend an Oxisol from the centre region of Cameroon. The different composts were mixed with the soil in 1/4 proportions (w/w); the experimental design was a completely randomized block with three replicates per treatment. The different treatments were planted with soybean (Glycine max L.) for three month growing period. Compost amendment increased the soil pH, organic carbon, total nitrogen and total phosphorus. Bacterial and fungal biomass together with cellulase and protease activities also increased in amended soil. Following soil chemical, physical and chemical parameters, plant growth and yield also improved in compost treated sols. However, compost prepared with 15% wood ash additive showed trends of inhibition of the soil microbiota. It can be concluded that green waste wood ash compost could be used as a suitable soil fertilizer for tropical acid soils, although precautions are to be taken when using these composts prepared with addition of wood ash ≥ 15%.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Agricultural Depletion of Soil Nutrient in Arable Land
DR. RASHMI AHUJA
Prof. Department Of Chemistry,Govt. M.L.B. GIRLS P.G. COLLEGE, BHOPAL.
ABSTRACT
Land degradation is a concept in which the value of the biophysical environment is affected by one more
combination of human induced processes acting upon the land. Soil is the essence of life. Agriculturally soil is a
region supporting plant life and from which plants obtain their mechanical support and many of their nutrients. As
Indian economy is agricultural based, so to ascertain the role of nutrient in soil fertility and plant growth, this base
line survey was undertaken. In our country crop production is far below than population density, resulting in large
shortage of food stuff. It is estimated that up to 40% of world’s agricultural land is seriously degraded. Integrated
plan nutrient management (IIPNM) adopted scientifically to ensure greater sustainability in agricultural
development which combines economic and efficient traditional and frontier technologies to gain from the
symbiosis and synergy of crop soil environment biointeractions.
Key words - : arable, nutrients, solvent extraction, depletion.
INTRODUCTION
Soil is a marvelous substance, a living resource of terrestrial animals, plants and microorganisms. Soils are the
fundamental resources supporting agriculture and forestry as well as contributing to the aesthetics of a green planet.
Agricultural depletion of soil nutrients through poor farming practice the major cause of land degradation which is
global problem related to arable land nutrients. There 17 elements identified as essential for plants growth. Out of
these 14 elements are classified into two groups based on their on their amounts needed by the plants.
Soil chemists in the field of agronomy started serious investigation since the beginning of the last
century to ascertain the role trace level elements in soil fertility and plant growth. The presence of trace levels of N,
Zn, B, Ca, P, C, Cl, Fe, Co, K, Cu, Mg, Cr, Mn, S, Se and V in soil have direct relevance to soil fertility and plant
growth. It was reported that the importance of the controlled amount of manganese in the soil and the quality of
crop production. Few scientists confirmed the indispensible role of Zn and B in the growth of higher green plants.
In the present article the comparative study of diploid nutrient in arable lands from different areas of
Bhopal within one year of period shall be reported. The main objective of the current investigation is twofold
firstly, to establish simple but reliable method for trace level analysis, secondly, to ascertain the chemical
composition of soil as well as depletion of nutrients. These essential elements are classified into two groups based
on their amounts needed by the plant. Micronutrients used by the plants in very small amounts and macronutrients
in a very large amounts. Lack of anyone of them in soil can limit plant growth, even when all other nutrients are
present in adequate amounts.
EXPERIMENTAL:-
For the collection of soil, variation in slope, color, size, crop growth and management has been taken into account.
The soil samples must perfectly represent the area. Five separate sets of composite samples from distant arable
areas of different sizes, texture and color were collected twice after an interval of a year.
LABORATORY WORK DONE :-
• Pre treatment, processing and storage of samples.
• Mechanical analysis of soil (texture, size, etc.).
• Water holding capacity of soil (moisture content).
• Determination of E.C. (electrical conductivity).
• Determination of pH.
• Determination of organic carbon.
• Determination of calcium carbonate.
• Determination of nutrient availability.
• Comparison of soil fertility.
Common A/R grade reagents and doubly distilled water were used for solution preparation. Finely ground
soil samples were sieved through a 0.2 mm mechanical sieve and dried in an oven at 150o
C for 24 hours. 1 gm of
dried soil was transferred into a crucible and 10 cc of HNO3 was carefully added to it. The mixture was slowly

digested on a hot plate inside a fume hood up to a few hours near to dryness. The residue was cooled and then
digested for 10-15 min. with a mixture of conc. acids HNO3, HCl and HF in 1:2:1 ratio. The mixture was heated
slowly until dense white fumes stated coming off and volume was reduced to approximately to 5 cc. The crucible
was removed from the hot plate and cooled to room temperature before making up the volume of the solution to
50 cc with distilled water. Without soil a solution blank was also prepared in the same way.
Elements in the digested soil sample were separated by solvent extraction involving the selective use of pH,
masking agent and the solvent. Atomic absorption spectrometer was used for the determination of few nutrients.

RESULTS AND DISCUSSION : -
Comparison between the concentration of various nutrients present in soil sample after interval is given in the table.
The presence of nearly twenty elements at micro level in soil is necessary as essential nutrient for the growth of
plants.
Physicochemical condition of the soil is one of the important parameter that determines if it is able to
supply the necessary nutrients to plant. From the result it is evident that with the exception of Mg, Mo and Se,
concentration of the remaining nutrients included in this study are much higher in the initial stage. However with
the exception of very low levels of N and P in the later, nutrient contents in both the sets are comparable but shows
gradual depletion. It is therefore logical to conclude that the lack of plant growth necessarily arises from the
deficiency of nutrients in the soil, rather the way these are distributed.
Failure of nutrient uptake by plants may result from a no. of important factors such as :-
1. pH of the soil, if too high, the essential nutrients may remain in the solid form which prevent the
available nutrients from being passed on to the plants.
2. Loss of nutrient through soil erosion due to high rainfall.
3. Extremely high drop of temperature during winter and as high as 48o
C in summer

Combined effect of these factors may result in the land being arid (unproductive).
CONCLUSION :-
In our country crop production is far below than population density, resulting in shortage of food stuff. It is
suggested that the failure of land to supply the available nutrients for sustainable growth of plants results from
infiltration of soil nutrients in soil as soluble matter which are not readily available to the plant. Reports also claim
that significant loss of N in the form of NH3 and P in the form of PO4 occur unless the soil organic carbon
management is done on a routine basis. The analytical data obtained in this investigation should provide an
incentive for a depth investigation with the special emphasis on how best the soil pH and Mg content be adjusted
for sustainable and increased productivity. Integrated plant nutrient management adopted scientifically to ensure
greater sustainability in agricultural development.
Major components of integrated nutrient supply and management system which need attention are: -
• Popularizing biofertilizsers to augment N and P supply.
• Promoting balanced use of chemical fertilizers (NPK) based on soil testing and correction of
micronutrients deficiencies in soil. Integration of green manures.
• Promoting agronomic practices that maximize nutrient use.
• Using sewage and sludge and effluents for agriculture.
