Soil Erosion AND ITS Management SITE

---
Hello;

Welcome to soil Erosion site

This website is to educate you guys about soil ersoion and its conservationits effects on environment. This is website gives a detalied information on soil erosion

lets do our best to stop soil erosion

Climate

The amount and intensity of precipitation is the main climatic factor governing soil erosion by water. The relationship is particularly strong if heavy rainfall occurs at times when, or in locations where, the soil's surface is not well protected by vegetation.

Soil structure and composition

affects the permeability of the soil to water, and hence the amount of water that flows away as runoff. 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

Vegetative cover

Vegetation acts as an interface between the atmosphere and the soil. It increases the permeability of the soil to rainwater, thus decreasing runoff. It shelters the soil from winds, which results in decreased wind erosion, as well as advantageous changes in microclimate

Topography

The topography of the land determines the velocity at which surface runoff will flow, which in turn determines the erosivity of the runoff. Longer, steeper slopes (especially those without adequate vegetative cover) are more susceptible to very high rates of erosion during heavy rains than shorter, less steep slopes.

Factors affecting soil erosion

Physical Factors

Tillage Erosion

Tillage erosion is a form of soil erosion occurring in cultivated fields due to the movement of soil by tillage. Tillage erosion results in soil degradation, which can lead to significant reduction in crop yield and, therefore, economic losses for the farm

Surface RUNOFF

Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four)

Floods

At extremely high flows, kolks, or vortices are formed by large volumes of rapidly rushing water. Kolks cause extreme local erosion, plucking bedrock and creating pothole-type geographical features called Rock-cut basins.

Rivers and Streams

Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from changes on the bed of the watercourse, which is referred to as scour. Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times

Human Activites

HUMANS HAVE ALSO PLAYED A MAJOR ROLE IN SOIL EROSION . HUMAN FOR THEIR DAILY NECESSITY DESTROY THE ECOLOGICAL BALANCE AND SOME FACTORS RESULTED IN SOIL EROSION ARE:-
>Improper Agricultural Practices
>Deforestation
>Climate Change
>Global Warming

MONITORING OF THE SOIL EROSION

the most commonly used model for predicting soil loss from water erosion is the Universal Soil Loss Equation (USLE). This was developed in the 1960s and 1970s. It estimates the average annual soil loss A on a plot-sized area as:[98] A = RKLSCP where R is the rainfall erosivity factor, K is the soil erodibility factor, L and S are topographic factors[102] representing length and slope, C is the cover and management factorand P is the support practices factor.

PREVENTION AND REMEDIATION OF SOIL EROSION

SLOW

a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming. This type of landscaping is therefore called terracing.

Course Two

Mixed cropping can be defined as the practice of growing two or more crops on the same piece of land at the same time.

Mixed Frming

Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the reliance of crops on one set of nutrients, pest and weed pressure, along with the probability of developing resistant pests and weeds.

Crop Rotation

A windbreak (shelterbelt) is a planting usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted in hedgerows around the edges of fields on farms

Wind Break

Carbon sequestration is the process of storing carbon in a carbon pool.Carbon sequestration is a naturally occurring process but it can also be enhanced or achieved with technology, for example within carbon capture and storage projects. There are two main types of carbon sequestration: geologic and biologic

carbon sequestration,

They generally occur in the form of a rigid wall that is built across the base or inclined portion of a slope.

Retaing Walls

role of groins is to control erosion caused by longshore drift along the coast. They are usually built as sturdy barriers obstructing the path of incoming water currents.

Groins and Jetties

temporary structures built from rock material, debris, or compost.Silt fences may absorb runoff and trap eroded soil.

Silt Fences

the use of organic materials like leaves and wood waste to cover the soil .

Organic Mulching

It involves the use of sustainable techniques such as rotational grazing to reduce the point-concentration of cattle within any pastoral land.

Conservative grazing

the cultivation of crops in well-defined rows that are aligned with the topographic levels or contour lines across the surface of a slope.
