Soil containing high levels of organic materials are often more resistant to erosion, because the organic materials coagulate soil colloids and create a stronger, more stable soil structure.

Soil erosion rates are expected to change in response to changes in climate for a variety of reasons.

Soil erosion ( especially from agricultural activity ) is considered to be the leading global cause of diffuse water pollution, due to the effects of the excess sediments flowing into the world's waterways.

Soil particles picked up during wind erosion are a major source of air pollution, in the form of airborne particulates —" dust ".

The most commonly used model for predicting soil loss from water erosion is the Universal Soil Loss Equation ( USLE ), which estimates the average annual soil loss as:

simple: Soil erosion

Soil erosion forced them, however, to abandon their land and move deeper into the rainforest.

Soil erosion and dust storms were also a problem in Nicaragua at the time due to deforestation.

Soil erosion due to improper land and plough utilization is possible.

* Soil erosion

Soil is composed of particles of broken rock ( parent materials ) which have been altered by chemical and mechanical processes that include weathering ( disintegration ) with associated erosion ( movement ).

** Soil erosion – process by which soil is removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations.

Soil nutrients diminish and erosion increases.

# Soil surface: cover crops to retain soil and lessen erosion, along with green manures to add nutrients and organic matter to the soil, especially nitrogen

Soil erosion due to weather and human activities and clearing of wood and brush for such uses as charcoal and fuel are issues leading to a degradation of the environment.

Soil erosion is fast becoming one of the worlds greatest problems.

" Soil erosion is not unique to Africa but is occurring worldwide.

In the United States, federal programs administered through local Soil and Water Conservation Districts provide technical assistance and partial funding to farmers who wish to implement management practices to conserve soil and limit erosion.

* Soil erosion

Soil erosion, due to extensive logging and intensive farm practices is a major issue.

Soil Conservation-The nature of dryland farming makes it particularly susceptible to erosion, especially wind erosion.

* Soil erosion is minimized.

Soil redeposition is evaluated by washing clean swatches with the dirty ones.

Soil with a pH value higher than 7. 3 is normally referred to as alkaline.

Clay identification is determined by a process of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation.

Soil is contaminated through particulate accumulation from lead in pipes, lead paint and residual emissions from leaded gasoline that was used before the Environment Protection Agency issue the regulation around 1980.

Environment-current issues: Soil salinity is rising.

According to the Soil Association, the total copper that can be applied to organic land is 6 kg / ha / year.

Its label states it is approved by the Soil Association and the Vegetarian Society.

Soil is a natural body consisting of layers ( soil horizons ) that are primarily composed of minerals which differ from their parent materials in their texture, structure, consistency, colour, chemical, biological and other characteristics.

Soil is the end product of the influence of the climate ( temperature, precipitation ), relief ( slope ), organisms ( flora and fauna ), parent materials ( original minerals ), temperature, and time.

Soil is altered from its parent material by the interactions between the lithosphere, hydrosphere, atmosphere, and biosphere.

Soil is commonly referred to as " earth " or " dirt "; technically, the term " dirt " should be restricted to displaced soil.

Soil pH, a measure of the hydrogen ion ( acid-forming ) soil reactivity, is a function of the soil materials, precipitation level, and plant root behavior.

Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological, and anthropogenic processes on soil parent material.

Soil is said to be formed when organic matter has accumulated, and colloids washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum.

Soil is said to be formed when detectable layers of clays, organic colloids, carbonates, or soluble salts have been moved downward.

Soil is always changing.

Soil texture is determined by the relative proportion of the three kinds of soil particles, called soil " separates ": sand, silt, and clay.

Soil density, particularly bulk density, is a measure of soil compaction.

Soil is not only a support for vegetation, but it is also the zone beneath our feet ( the pedosphere ) of numerous interactions between climate ( water, air, temperature ), soil life ( micro-organisms, plants, animals ) and its residues, the mineral material of the original and added rock, and its position in the landscape.
