Mulching means different things to different people. Covering seems to be a key word in most definitions.
Soil erosion is a major environmental problem throughout the developing world.
The problem is increasing rapidly, not only because more land is being cleared, but because farmers are being forced onto steeper, more fragile lands as arable land on gentle slopes becomes unavailable. Soil losses of hundreds of tons per hectare per year are common on steep slopes with some annual crops. The use of various soil covers, especially mulches, to reduce erosion is becoming recognized as one of the most effective strategies for reducing soil erosion on steep hillsides.
