Soil physical properties sixth Presentation by Allah Dad Khan Mr.Allah Dad Khan
The document discusses various physical properties of soil, including mass or weight, volume, pores, surface area, texture, structure, color, and bulk density. It defines key terms like texture, pores, surface area, and provides classifications for soil structure and texture. Texture is defined as the relative proportion of sand, silt and clay in a soil. Structure refers to the arrangement of primary soil particles into aggregates. The document also examines factors that influence these physical properties.
This document provides an overview of soil, including its 6 major components, importance, formation processes, properties, and conservation. Soil is formed through the weathering of rock and decay of organic matter. It consists of minerals, water, air, and living organisms. Soil is important as it provides nutrients for plants, recycles water, and stores water and carbon. Soil type is determined by texture, permeability, porosity, and other factors. Proper soil management through practices like contour plowing and crop rotation can reduce erosion and maintain soil quality.
Sandy soil consists of large particles that allow for good drainage but can dry out plants. Clay soil is made of very fine particles that make it difficult to work with due to poor drainage and risk of waterlogging. Loamy soil balances sand, silt and clay for good texture, water retention and drainage. Chalky soil is alkaline with many stones and prone to dryness. Peaty soil is rich in organic matter but low in nutrients unless well fertilized and drained. The subsoil below the topsoil may not contain nutrients for plants.
The document discusses soil profiles and their components. A soil profile is a cross-sectional view of soil and consists of different horizons. The topmost horizon, O horizon, contains mostly organic matter. The A horizon below it is topsoil with good amounts of organic matter and minerals. The B horizon, or subsoil, has less organic matter. The lowest C horizon is mostly parent material and does little for plant growth.
Soil is the thin layer of material on Earth's surface that supports plant growth and provides nutrients. It is formed over thousands of years from weathered rock and organic materials. There are many different soil types worldwide based on factors like climate, topography, and biology. Soil is a non-renewable resource that is important for food production, water regulation, and carbon storage, yet a third of soils are degraded. Maintaining soil health through sustainable management practices is crucial for food security and the environment.
This document discusses the components and layers of soil. It explains that soil is made up of five main components: rock, sand, silt, clay, and humus.

Aggregate stability refers to the ability of soil aggregates to resist disruption when exposed to outside forces like water. It is an indicator of soil quality, with greater stability suggesting better soil quality. Stable aggregates provide pore space for air, water, and biological activity in soil. Factors that influence aggregate stability include soil texture, clay type, organic matter, iron and calcium levels, and microbial populations. Management practices like tillage can degrade stability while conservation practices like cover crops and reduced tillage can improve it.
This document discusses irrigation water management. It notes that declining groundwater levels and restrictions on new irrigated acres mean irrigators need to schedule irrigation applications carefully. Proper irrigation scheduling involves routinely measuring soil water status, rainfall, irrigation applied, and estimating crop water use. The goal is to irrigate with appropriate amounts and frequencies to match crop needs. Over-irrigation can reduce yields, increase costs, and contribute to groundwater contamination. Key factors for proper irrigation management include having an irrigation system designed for efficient water delivery, flow meters, rain gauges, soil moisture sensors, and reliable crop water use information.
This document discusses the importance of soil organic matter. It states that soil organic matter affects chemical and physical soil properties and overall health. It is made up of living and dead biomass and humus. Soil organic matter content typically ranges from 1-6% and provides benefits like improved structure, water retention, and nutrient availability. Maintaining or increasing soil organic matter through practices like reduced tillage, cover crops, and reducing erosion can improve soil quality and sustainability.
This document discusses the physical properties of soils, including soil separates, texture, structure, density, porosity, permeability, and color. The key points are:
- Soils are composed of particles of different sizes called soil separates - sand, silt, and clay. The relative percentages determine the soil texture (e.g. sandy loam).
- Soil structure refers to how the particles are arranged and can impact properties like drainage. Common structures include granular, blocky, and platy.
- Other important physical properties include density, porosity (amount of pore space), permeability (how quickly water/air can move through the soil), and color which provides information about the soil composition.
The document discusses the components and properties of soil. It describes the origins of soil parent material as being residual, transported, or cumulose. Soil develops layers over time from weathering of parent materials. Soil consists of solids, liquids, and gases, with mineral matter, organic matter, water, and air making up its volume. Key properties of soil discussed include color, texture, structure, consistence, and fertility/productivity. Texture refers to particle size and affects water holding and workability. Structure and consistence influence aeration and drainage.
This document provides an overview of sustainable soil management. Part I discusses the characteristics of living soil, including the importance of soil texture, structure, organisms, and organic matter. Soil is a living ecosystem containing billions of organisms per acre that cycle nutrients. Practices like no-till and cover crops help build soil quality by supporting earthworms and other beneficial soil life. Part II will cover specific management steps to improve soil, and Part III profiles farmers successfully building soil.

Background
Soil Horizons and Chemical Composition
The type of dirt that makes up the dry
surfaces of the earth has numerous effects on
humans and the environment, and vice versa.
Humans can modify the suitability of some
areas for agriculture based on prior land use.
The properties of soil also determine water
availability in a given area. Areas that contain the
most suitable soil for farming are often limited.
Certain properties of soil determine whether
an area is suitable for human activity. When
considering the properties of soil, its texture,
shape, particle aggregation, and suitability for
growth come to mind. These properties all play
a major role in determining the capability of an
area to retain water and air, which are necessary

To minimize the impact of drought, a soil needs to capture rainfall, store water for plant use, and allow for deep plant root growth. These conditions can be achieved by managing organic matter, aggregation, and ground cover. Organic matter increases water storage capacity by 16,000 gallons per acre-foot for each 1% increase in organic matter. It also improves aggregation and water infiltration. Maintaining ground cover increases infiltration while lowering evaporation. Together, these factors can greatly reduce the need for irrigation during drought by enhancing the soil's ability to store water and make it available to plants.
Chapter 3 soil water and irrigation practice1Mulugeta Abera
This document summarizes key concepts about soil water and irrigation practices. It discusses how soil serves as a storehouse for water and nutrients that are essential for plant growth. The document then describes the three-phase system of soil consisting of solids, liquids, and gases. It explains how soil texture, structure, and physical properties influence the soil's water holding capacity and retention. Different types of soils like sandy soil, loamy soil, and clay soil are characterized. The concept of bulk density, porosity, and soil moisture content on a mass and volume basis are introduced to quantify the water in soil. Maintaining proper soil water levels through irrigation is important for optimal plant growth and yield.
Ground Improvement of Dune Sand Fields For The Purpose of Moisture RetentionIJERA Editor
Plant growth depends on the use of two important natural resources, soil and water. Soil provides the mechanical and nutrient support necessary for plant growth. Water is the major input for the growth and development of all types of plants. The availability of water, its movement and its retention are governed by the properties of soil. The properties like bulk density, mechanical composition, hydraulic conductivity etc depends on the nature and formation of soil and land use characteristics in addition to the weathering processes and the geological formations. Effective management of the resources for crop production requires the need to understand relationship between soil, water and plants. Study of soil and its water holding capacity is essential for the efficient utilization of irrigation water. Hence identification of geotechnical parameters which influences the water retention capacity and the method of adding admixtures to improve the retention capacity play an important role in Irrigation Engineering. This Paper aims to focuses on improving moisture retention of soil by addition of bentonite clay and experimental analysis for monitoring the variation of moisture retention.

Ruth Jones, a Christian teacher without a master's degree or administrative experience, was unexpectedly named principal of a struggling inner city elementary school in Grand Rapids, Michigan that was on the verge of closure due to poor academic performance. Through prayer, addressing students' practical needs, and recruiting volunteers, Jones led a dramatic turnaround of the school over 20 years. Test scores and graduation rates increased sharply, and the school now has a waiting list despite originally facing closure. Jones attributes the school's success to aligning herself with God.
- Coconut oil may help slow or prevent Alzheimer's disease in some people by providing an alternative fuel for brain cells in the form of ketones. Dr. Mary Newport put her husband Steve, who had Alzheimer's, on a diet supplemented with coconut oil, which led to improvements in his symptoms and cognitive abilities.
- Researchers have developed a ketone ester that is more potent than coconut oil, but it is very expensive to produce. Coconut oil remains a viable alternative source of ketones. Taking coconut oil may also help with other neurological diseases due to its ability to increase ketone levels and good cholesterol while reducing bad bacteria.
A teacher in Baltimore transformed the lives of students from the slums. In the 1920s, college students evaluated 200 boys from the slums and said they had no chance of success. Twenty-five years later, it was found that 176 of the 180 boys who could be located had achieved success as lawyers, doctors, and businessmen. The professor interviewed each man and they all credited their success to a teacher who had loved and believed in them. When interviewed, the elderly teacher said her simple method was that she loved those boys.
Robert Raikes witnessed the poor conditions of children in Gloucester, England in the late 18th century due to the Industrial Revolution. This inspired him to create the first Sunday school to educate and reform street children. The Sunday school used the Bible as its textbook and proved hugely successful in improving behavior and civic responsibility. Raikes' idea then spread across Britain and to other parts of Europe and America, revolutionizing religious education of children and community outreach efforts of churches. Late in life, Raikes had a profound spiritual experience witnessing a young girl reading the Bible that gave him a new understanding of faith.
The document discusses using Groasis Waterboxx devices to help plant and grow trees in dry environments like the Sahara Desert. It describes how the author and a colleague tried using 10 Waterboxx devices to plant trees in M'hamid, Morocco but their luggage containing the devices was initially lost. They were eventually found and the devices were used to plant tamarisk trees to compare growth with traditional planting methods. The document provides details on how the Waterboxx works, collecting condensation and directing water to tree roots, and hopes the experiment will help increase tree survival rates in the dry climate.
The Groasis Waterboxx is a low-tech device that helps seeds and saplings grow into strong trees in dry environments. It collects and stores rainwater and condensation to slowly water the roots daily. In tests, 88% of trees grown with the Waterboxx survived compared to only 10.5% without it. The inventor believes using this technology could reforest billions of acres and offset humanity's carbon emissions by capturing CO2 in new tree growth.
The document discusses the Groasis Technology, a planting method that uses a Waterboxx and other techniques to plant trees in dry areas with 90% less water. It summarizes that the technology (1) improves soil, maps planting areas, harvests rainfall, and uses the right planting techniques to help trees grow deep roots in the first year to survive independently. It also describes how the technology terraces slopes to harvest and direct rainfall to trees, uses 3D imaging to map ideal planting lines, and a capillary drill to quickly plant thousands of trees per day.
The document describes the Agua, Vida y Naturaleza Project (AVNP) that started in Ecuador in 2012. It is funded by the Dutch COmON Foundation to help small farmers in dry areas by introducing the Groasis Technology, which allows planting in deserts and eroded lands. The technology mimics nature by improving soil, maintaining capillary structures, and using a waterboxx device. The project aims to address issues small farmers face like lack of water, capital, and farming knowledge, in order to help alleviate world hunger and prevent farmers from migrating to cities due to lack of income from farming dry areas.
The document provides planting instructions for using a Waterboxx planting device. It outlines 6 main steps:
1. Preparing the soil by digging holes and adding compost/fertilizer or just watering.
2. Assembling the Waterboxx by placing the wick, mid-plate, lid, and siphons.
3. Preparing plants by pruning roots to encourage deep growth.
4. Planting in holes aligned east-west within the Waterboxx hole.
5. Placing the assembled Waterboxx over the planted area.
6. Watering the plants and filling the Waterboxx for the first time.
This document provides instructions for growing vegetables using the Groasis Waterboxx system. It details recommendations for greenhouse design, soil preparation, planting methods, plant spacing, watering schedules, and pest and disease management. Proper installation and maintenance of the Waterboxx system is emphasized to ensure healthy plant growth and high crop yields. Close monitoring of climate conditions and plant needs is also advised.
The document is a report on the Groasis waterboxx, a device that aims to allow farming without irrigation. It provides an overview of the waterboxx's history and development, describes its components and how it works, reviews testing that has been done, and evaluates its suitability for organic farming. In the conclusion, the report recommends that the cooperative discussed in the document not use the waterboxx yet, as more data is still needed, but could consider conducting their own tests with support from their technical services.
The document summarizes an invention called the Groasis that helps plants survive in arid climates by collecting and storing rainfall to provide steady watering to seedlings. It notes that most rainfall in deserts occurs within one week but is then unavailable, and that the Groasis uses evaporation-proof containers and wicking to deliver water to young plants over longer periods, allowing their roots to develop and access deeper groundwater reserves. Large-scale projects have used the Groasis in countries like Kenya to aid reforestation efforts and combat desertification.
The document summarizes the work of the Sahara Roots Foundation in Morocco and their use of the Groasis Waterboxx to help plant trees and reduce desertification. The Sahara Roots Foundation was established to implement development projects to conserve the Moroccan Sahara through activities like tree planting, irrigation, education, and desert cleaning. They have started using the Groasis Waterboxx, an "intelligent water battery" developed by AquaPro, to improve the survival rate of newly planted trees. The Waterboxx produces and captures water through condensation and rain, allowing trees to be planted in dry areas like rocks and deserts with a 100% success rate.
The document describes the Agua, Vida y Naturaleza Project (AVNP) that started in Ecuador in 2012. It is funded by the Dutch COmON Foundation to help small farmers in dry areas by introducing the Groasis Technology, which allows planting in deserts and eroded lands. The technology mimics nature by improving soil, maintaining capillary structures, and using a waterboxx device. The project aims to address issues small farmers face like lack of water, capital, and farming knowledge, in order to help alleviate world hunger and prevent farmers from migrating to cities.
Groasis Technology is compared to drip irrigation over a 50-year project for a 500-hectare tree plantation. Key financial indicators show that using Groasis Waterboxes results in a higher net present value (NPV) of €26.62 million compared to €21.15 million for drip irrigation, and a slightly higher internal rate of return (IRR) of 22.1% versus 23.4% for drip irrigation. Waterboxx also has a longer payback period of 7 years compared to 5 years for drip irrigation. The document provides assumptions and calculations for costs and revenues for both systems over the 50-year period.
A new technology called the Groasis Waterboxx shows promise for reclaiming desert landscapes and increasing plant survival rates. The simple device regulates temperature and moisture levels around young plants, allowing trees and crops to grow with little watering even in dry conditions. Initial trials in Africa found tree survival rates increased to 88% with the Waterboxx compared to only 10% without it. Researchers in Kenya are optimistic this technology could significantly reduce desertification and help transform the country's deserts into productive, economic areas through increased vegetation.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
