Non Point Source Pollution

Most lakes in the eastern part of China are eutrophic and non-point pollution accounts for more than half of the nutrient load to the lakes and reservoirs. Some efforts have been made to reduce the non-point source pollution in the catchments of sensitive water bodies. Technologies for the control of non-point pollution in Chinese rural areas are multipond systems, biogas fermentation, hilly area ecological agriculture, constructed wetlands, ecotone engineering and others. They are effective in the removal of nutrients from the runoff water or reduction of waste, and they are used with multi-purposes. To control non-point pollution, the cooperation with farmers and other residents in the countryside is the key to success, and the program has to consider their benefits. There are still many difficulties with its control, and more efforts are needed to develop suitable technologies and environmental education.

Non Point Source Pollution

Using manure as a substitute for commercial fertilizer could potentially reduce fertilizer costs and also reduce non-point source pollution. Livestock farmers in Missouri and Iowa were surveyed regarding their manure management practices. Eighty-one percent of turkey farmers versus 5% of beef farmers transferred manure to other farmers. Fifty-one percent of farmers who transferred manure indicated it had been tested. Factors decreasing adoption included higher off-farm incomes, solid versus liquid manure, and more animal units per acre. Factors increasing adoption included distance transferred, a contract for the manure, payment, and thinking that manure testing was profitable.
