Answer 1

• to reduce cost of production.
• To control soil erosion e.g through mulching and cover cropping
• to maintain soil structure .continuous cultivation destroys soil structure and should be avoided.
• conserve soil moisture ie.soil is not exposed to strong sun heat there reducing evaporation
• Prevent the distribution of the roots underground structures
• Prevent exposure of humus to adverse conditions eg strong sun heat which can cause volatilization.
