Özet

As part of its environmental compliance program required for joining the European Union, Turkey must deal with the problem of excess runoff of nutrients from both chemical fertilizers and manure into water. Manure and other fertilizers cause eutrophication and other water quality problems. It had been thought that phosphorus, which is in manure as well as chemical fertilizers, was so strongly bound to soil particles that it did not readily leach into water. However, recent studies show that phosphorus is mobile and so poses a threat to water quality.
