NEET BIOLOGY

Detailed explanation-1: -Soil is a non-renewable resource; its preservation is essential for food security and our sustainable future.

Detailed explanation-2: -Soil is considered a renewable resource because it can be restored on a human timescale. When soil is lost by erosion it can be recovered fairly rapidly (a few decades) if better soil management practices are carried out. The fertility of soil can also be restored in a few years and thus soil is a renewable resource.

Detailed explanation-3: -When the rate of soil formation exceeds the rate of degradation, soils are renewable. In areas where degradation exceeds formation, soils are non-renewable (at least until the next climate shift). Some types of degradation can be managed to maintain productivity.

Detailed explanation-4: -Although renewable, soil takes a very long time to form-up to hundreds of millions of years. So, for human purposes, soil is a nonrenewable resource. It is also constantly depleted of nutrients through careless use, and eroded by wind and water.
