of land degradation PREPARED BYMD. SARWAR JAHAN TALUKDARROLL : 16 AG ENVS JD 11 M

Land Degradation Land degradation: It can be defined as the less of productivity

(temporary & permanent) due to detrition of lands quality.

Physical Soil structure Water holding

capacity Soil erodibility Soil porosity

We can say a land is degraded when we will see changes on this components listed below:

ChemicalpH Nutrient

status

Biological o Bacteria o Fungio Nematode
