Abstract

Agriculture, unlike industrial activity which has always resulted in pollution, has been environmentally benign for most of its history until after the Second World War when the system disintegrated. Then, crop residues were incorporated into the soil or fed to livestock, the manure returned to the land in amounts that could be absolved and utilized. Mechanized farming, however, is reliant on synthetic fertilizers and pesticides. Hence, crop residues and livestock excreta, which were once recycled have become wastes and their disposal a continuing problem for the farmer. With the present national policy on agriculture, there is the need for private sector participation especially in the area of environmental health and safety for economic and environmental sustainability.
