Subsurface drainage water; Nitrate-nitrogen losses

Sažetak
In a field trial with different mineral nitrogen doses (0, 100, 150, 200, 250 and 300 kg Nha-1) nitrate nitrogen losses in drainage water are quantified for the period from October 1997 to December 2007. The trail was set up so that the area of each fertilizing treatment embedded two drainpipes, in their full length. Water samples were collected on a daily basis during the periods of outflow. NO3-N concentration in drainage water varied in dependence on the crop type and development stage, on the fertilization, on the quantity and intensity of precipitation and on the drainage volume. Crop sequence at test field included corn, winter wheat, oilseed rape and soybean. Obtained results can be used for prediction of nitrogen losses with drainpipe water in regions with similar agro-ecological conditions.
