Farmers often unknowingly cause harm to the environmental system. They should be taught that the excessive use of fertilizer and pesticides has a huge adverse impact on the whole ecosystem. Thus, by increasing the farmers’ knowledge and awareness, agricultural pollution can be mitigated to a certain degree. They must know: 1 Applying the right quantity of pesticides and fertilizers that are necessary to get a reasonable crop yield. 2 Using cover crops to prevent bare ground when the actual harvest is over, thus preventing soil erosion and loss of waterways. 3 Planting grasses, trees and fences along the edges of a field that lies on the borders of water bodies. They could act as buffers, and nutrient losses can be avoided by filtering out nutrients before reaching the groundwater. 4 Reduction in tillage of the fields in order to reduce runoffs, soil compaction and erosion. 5 Animal or cattle waste is a big cause of agricultural pollution. The management of these pollutants is crucial. 6 Several manure treatment processes need to follow, which aim to reduce the adverse impact of manure on the environmental system.
