MODIFICATION OF BIOCHEMICAL PROPERTIES BY SOIL USE

Human activity is one of the main causes of the physical, chemical and biological degradation of soils. This degradation implies a change in soil quality as it involves both a decrease in productivity and changes in the ecological functions of the soil. The objective of the present study was to inve...
