Nitrogen balance and mineral nitrogen content in the soil in a long experiment with maize under different systems of N fertilization

Original language description

The effect of different systems of N fertilization on nitrogen balance and N transformation in the soil was studied in long-term stationary experiments (1991-2002) with successive growing of maize. Average nitrogen uptake by the aboveground biomass was 116 kg N.ha-1 for the control, 162 - 170 kg N.ha-1 for fertilization treatments. All experimental treatments had a negative balance of N inputs and outputs, and it was -1 394 kg N/ha for the control (for 12 experimental years). After the application of mineral fertilizers, a lower content of total carbon and nitrogen was measured in the topsoil compared to the control and treatments with organic fertilization. Soil lysimeters were installed in these experiments (depth 60 cm, size 0.2 m2). For an eight-year period (1994/2002) 11.78 kg N-NO3-.ha-1 were determined in lysimetric waters.
