This program will discuss the erosion process, its effects on crops and the environment, and the Best Essay on soil erosion Practices that can be implemented to limit or contain soil movement from the land. Soil erosion can be divided into two very general categories: · Geological erosion: Geological erosion occurs where soil is in its natural environment surrounded by its natural vegetation.

A classical example of the results of geological erosion is the Grand Canyon.
Accelerated erosion is the type that will be covered in most depth. It includes such problems as The essay on soil erosion of wind on exposed sediments and friable rock formations causes erosion abrasion and entrainment of sediment and soil.

It includes such problems as The action of wind on exposed sediments and friable rock formations causes erosion abrasion and entrainment of sediment and soil. This can be done by resorting to cover cropping by growing groundnut or berseem a fodder crop or through grasslands development by growing grasses like dub, kudzu, pans and dinanath. This practice consists of growing erosion-permitting crops jowar, bajra, maize in alternate strips with erosion checking close- growing crops grasses, pulses.
The erosion checking strips check and hold the flowing water and soil. This refers to growing of two or more different crops in sequence in a field for maintaining the soil fertility. Continuous growing of clean-cultivated crops e. A good rotation should include densely planted small grains, spreading legume which may check soil erosion. This means leaving crop residue or vegetative litter on the land as a surface protection against erosion and for conserving moisture by favouring infiltration and reducing evaporation. Organic manures like cowdung, green manure, farmyard manure etc. Granular and crumby structures increase infiltration and permeability in the soil and conserve soil moisture. Other measures include checking overgrazing, reducing surplus cattle, stopping shifting cultivation and taking preventive measures against forest fires.
On sloping lands, all tillage operations should be done at right angles to the slope of the land. This way, each furrow intercepts the flowing water and allows it to soak into the soil. The idea is to break the slope of the land into smaller, more level compartments by constructing mechanical structures of suitable size along contours. Each bund, thus, holds the rainwater within each compartment. On steeper slopes, terraces or flat platforms are constructed in steps in a series along the slope. This way water is retained on each terrace which can be used to raise crops. This refers to scooping out small basins at regular intervals on slopes which help in checking the run-off and in conservation of water.
This refers to trapping or channeling of water into low-lying areas. This helps in checking the run-off and also acts as a flood control measure. The cropping activity on slopes should be taken up as per the nature of slope. If the slope is between and , proper farming can be done; if more, pastures should be developed; if still more, forestry operations can be undertaken; if it is still greater, then terracing is required before any cropping activity can be done.
