dc.description.abstractAs 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. For this study, soil testing for phosphorus was performed in 832 fields within a 133,000 ha area in the Canakkale province of northwest Turkey. The region is dominated by crop fields, and also a large number of livestock. Soils were classified into five categories with respect to phosphorus sensitivity. Satellite imagery was used to calculate the size of each class. Over 70,000 hectares of cropland were classified as phosphorus-sensitive due to overapplication of chemical fertilizers. Chemical fertilizer applications increased not only the phosphorus values, but also the zinc content of the soil.
