What is rill erosion?
उत्तर
In rill erosion small finger-like rills begin to appear on the landscape. These rills are usually smoothened out by working of the farm implements. But, slowly the rills increase not only in number but also in their shape and size. They get wider and deeper. This reduces the actual area under crop and results in declining crop yields.
