dcterms:description
Changes in nitrate pollution in surface waters brought by the construction of tile drainage systems and by conversion of cultivated land to grassland (followed by decrease in fertilizer use) in two districts were examined. The goal was to find out how nitrate concentrations have responded to changes in agricultural management. There were no major changes in land use in the Pelhrimov district after 1990, apart from decrease in mineral fertilizer use. In the Cesky Krumlov district, permanent grassland area increased by 55% (from 228.9 km(2) to 353.3 km(2)) and by 241% (from 5.4 km(2) to 13 km(2)) in the catchments investigated between 1990 and 2000 followed by reduction in use of fertilizers. In these two districts, 31 small catchments where long-term, or repeated, nitrate concentration monitoring was carried out between 1986 and 2005, were analyzed. Trend, regression and factor analyses were conducted on changes in nitrate concentrations, and to assess the impact of several factors on nitrate concentra Changes in nitrate pollution in surface waters brought by the construction of tile drainage systems and by conversion of cultivated land to grassland (followed by decrease in fertilizer use) in two districts were examined.
