Answer 1

Physical factors, e.g. loss of fertile top soil due to water or wind erosion.

Chemical factors e.g. depletion of nutrients or the toxicity due to acidity or alkalinity (salinization) or water logging. ADVERTISEMENTS:

Biological factors which affect the micro-flora and reduce the microbial activity of the soil. These factors reduce the yield.
