1.1 The Impact of Agricultural Practices on Soil:
The intensive use of agricultural practices has a negative influence on soil quality and soil productivity (Lal, 2001). Moreover, Lal (2001) stated that the enhanced soil erosion by agriculture has many undesirable environmental impacts and will subsequently reduce crop production.
In addition, degraded soil and accelerated erosion in particular will affect water quality and the release radiatively active gases to the atmosphere (type of gases with the ability of absorbing arriving solar…
