Soil depletion occurs when the components which contribute to fertility are removed and not replaced, and the conditions which support soil's fertility are not maintained. This leads to poor crop yields. In agriculture, depletion can be due to excessively intense cultivation and inadequate soil management. The loss of fertile soil makes land less productive for agriculture, creates new deserts, pollutes waterways and can alter how water flows through the landscape, potentially making flooding more common. For all the fertility losses there are various causes in the different regions of the country, in totality the major causes to soil fertility decline is a land degradation which is caused through the different agents such as soil erosion, deforestation, overgrazing, sedimentation, continuous farming and pollution.

Soil fertility loss occurs when the quantities of nutrients removed from the soil due to chemical absorption into soil

In this situation, the nutrient requirements of the crop are met from soil reserves until these reserves cannot meet crop demands.
