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
