Název v původním jazyce

Simulation of nitrogen leaching and nitrate concentration in a long-term field experiment

Popis výsledku v původním jazyce

The effects of organic and mineral nitrogen fertilization on nitrogen leaching and nitrate concentration in percolated water were simulated using the CANDY model in a long-term IOSDV field experiment carried out from 1983 to the present in Lukavec. Increasing N rates from 0 kg to 200 kg N.ha-1 in mineral fertilizers were combined with the application of farmyard manure or straw, the control treatment was without organic fertilization. In the treatments, the average simulated nitrogen leaching ranged from 2 kg to 71 kg N.ha-1 y-1, the average nitrate concentrations were between 5 mg and 191 mg.l-1. Nitrogen leaching and nitrate concentrations were non-linearly related to the total nitrogen inputs (R2= 0.98), the organic fertilizer treatments had only negligible effect.
