Quantifying nitrogen leaching from diffuse agricultural and forest sources in a large heterogeneous catchment
Result description
Using mass budget and hydrological models, we quantified the contribution of major diffuse nitrogen (N) sources to surface water loading in a large heterogeneous catchment (upper Vltava river, Czech Republic, about 1,300,000 ha) over the last 52 years. The catchment reflects the typical development in central and eastern European countries, which witnessed socio-economic shifts from a market to a planned economy in the 1950s and back to a market economy in the 1990s. The former shift was accompanied byincreasing N inputs to agricultural and forest areas with ranges for the 1950s?1980s of 60?160 and 14?30 kg/ha/yr, respectively, and with intensive draining of waterlogged farmland. The shift in the 1990s resulted in 40% and 50% reduction of N inputs toagricultural areas and forests, respectively, and farmland draining ceased. The N exports from agricultural land (EAL) and from forests (EFO) varied within 3?45 and 1.6?7.1 kg/ha/yr, respectively (with maxima in the 1980s). The EAL and EF
