How does organic farming help in pollution control?
Chemical fertilizers, pesticides, and weedicides used in modern agriculture cause soil pollution. Further, chemical runoff contaminates surface waters and percolate into the groundwater creating water pollution. In organic farming, organic fertilizers, bio-pesticides are used and the emphasis is given on techniques like crop rotation, companion planting. Thus, in organic farming, no chemical fertilizers, pesticides, and weedicides are used which help in pollution control.
