what is soil erosion

Let us learn about what is soil erosion?

Erosion is refers to a natural process, but Soil erosion has been increased dramatically by human land use, especially industrial agriculture, deforestation, & urban sprawl

Soil erosion occurs when the soil is blown away by the wind or washed away by the rain. Soil erosion is common in region with steep slopes, where trees & plants have been cut down, in droughts when crops & other vegetation grow poorly & in rural areas which are overpopulated.

Soil erosion can be stopped by building terraces on hillsides, irrigation schemes to overcome droughts, planting more & more trees to bind the soil together & make wind breaks, & using fertilizers in overpopulated areas to make the soil more fertile. It is important that the farming techniques applied do not damage the structure of the soil, as this makes it easily eroded. A good farming technique consists of contour ploughing, crop rotation and keeping the soil rich in humus.


In our next blog we shall learn about elements compounds and mixtures I hope the above explanation was useful.Keep reading and leave your comments.
