Soil Acidity Soil pH. Soil acidity is measured in pH units. Soil pH is a measure of the concentration of hydrogen ions in the soil solution. The lower the pH of soil, the greater the acidity. pH is measured on a logarithmic scale from 1 to 14, with 7 being neutral. Soil pH is a measure of the concentration of hydrogen ions in the soil solution. 2  The lower the pH of soil, the greater the acidity. 3  pH should be maintained at above 5.5 in the topsoil and 4.8 in the subsurface.

- A sylviculturist, at work. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.he term is popularly applied to the material on the surface of the Earth's moon and Mars, a usage acceptable within a portion of the scientific community. Accurate to this modern understanding of soil is Nikiforoff's 1959 definition of soil as the excited skin of the sub aerial part of the earth's crust.

- To a soil scientist (the definition we'll use here), a soil is loose material, including mineral matter and organic matter, that supports plants and differs from the original parent material. (Parent material is the stuff that the soil formed from. 'Parent' is probably the wrong term, but is firmly entrenched.

Soil Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. The Earth's body of soil is the pedosphere, which has four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of Earth's atmosphere; it is a habitat for organisms; all of which, in turn, modify the soil. Soil interfaces with the lithosphere, the hydrosphere, the atmosphere, and the biosphere. The term pedolith, used

- Soil Erosion: Types, Agents and Conservation Practices. Soil Erosion: Types, Agents and Conservation Practices! Soil erosion is the process of removal of superficial layer of the soil from one place to another. Soil erosion leads to soil infertility as the top soil layer is lost and also ability of soil to hold water and sediment is reduced.

Soil Genesis and Development, Lesson 6 - Global Soil Resources and Distribution An important function of soil is to store and supply nutrients to plants. The ability to perform this function is referred to as soil fertility. The clay and organic matter (OM) content of a soil directly influence its fertility. Greater clay and OM content will generally lead to greater soil fertility.

- Soil degradation. Understand how the quality of soil declines and what causes this decline. Soil degradation is the decline in soil quality caused by its improper use, usually for agricultural, pastural, industrial or urban purposes. Soil degradation is a serious global environmental problem and may be exacerbated by climate change. It encompasses physical, chemical and biological deterioration. Examples of soil degradation include loss of organic matter, decline in soil fertility, decline in structural condition, erosion, adverse changes in salinity, acidity or alkalinity, and the effects of toxic chemicals, pollutants or excessive flooding.

How Does Lime Affect Soil? Soil pH. Soil pH is the measurement of how acidic or alkaline your soil is. pH stands for potential of H+ ions in a solution and is a way to measure the available hydrogen ions; the more hydrogen ions, the more acidic. The more hydroxyl (OH-) ions, the more alkaline.

What is soil moisture tension? Soil moisture is the amount of water contained in the soil after precipitation seeps into the ground. 1.The degree to which water clings to the soil is the most important soil water characteristic to a growing plant. This concept is often expressed as soil moisture tensi … on.

Soil Erosion Lab Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

Solving the soil erosion problem Soil erosion is a process in which soil quality and fertility diminishes, and the nutrient levels vital for food crop production are gradually depleted. Such degradation will eventually result in declining crop yield.

Tilth Soil tilth is its physical condition, especially in relation to its suitability for planting or growing a crop. Factors that determine tilth include the formation and stability of aggregated soil particles, moisture content, degree of aeration, rate of water infiltration and drainage. Tilth can change rapidly, depending on environmental factors such as changes in moisture, tillage and soil amendments.
