Nitrogen leaching from grassland ecosystems managed with organic fertilizers at different stocking rates

Popis výsledku v původním jazyce

This study shows the effect of organic fertilizers at different stocking rates, on nitrogen (N) leaching, measured using zero-tension lysimeters under undisturbed grassland soil. The experiment included two organic fertilizer types – cow dung with dung water (D) and slurry (S), both at a range of stocking rates: 0.9 LU (livestock unit) ha−1, 1.4 LU ha−1, 2.0 LU ha−1 (corresponding to 54, 84 and 120 kg N ha−1, respectively) and a control (C) treatment. In percolated water, the contents of ammonia nitrogen (NH4+–N) and nitrate nitrogen (NO3−–N) were studied. The average concentration of NH4+–N ranged from 0.91 to 1.44 mg l−1 on fertilized plots compared to 0.55 mg l−1 on the control plot. The average concentration of NO3−–N ranged from 5.2 to 9.5 mg l−1 on fertilized plots compared to 3.2 mg l−1 on the control plot. The results of this study showed that the use of organic fertilizers at chosen stocking rates influenced N leaching, but the concentration of N did not exceed the limits for drinking water permitted by Czech legislation. Stocking rates at 2.0 LU ha−1 and below do not result in elevated N concentrations in percolated water that pose environmental threat.
