Sažetak
Effect of nitrogen fertilization upon the concentration of nitrate nitrogen in subsurface drainage water was studied in field experiment with different mineral nitrogen rates. The trail was set up so that the area of each fertilizing treatment embedded two drainpipes, in their full length. One pipe was installed with and the other without gravel backfill. Trial treatments were: 1.Check&#8211 ; unfertilized, 2. N0 PK, 3. N100 PK, 4. N150 PK, 5. N200 PK, N250 PK, N250 PK + Phosphogypsum, N250 PK + Zeolite tuff + CaCO3, 9. N300 PK and 10. Black fallow. The first discharge used to take water samples from drainpipes occurred in mid November 1997 and the last one at the end of Decembar 2000. Average nitrogen leaching of 8.3 kgha-1 NO3- N was recorded in the check treatment, and 8.7 kgha-1 in treatment No. 2 with phosphorus and potassium. This was followed by treatment No. 3, in which 8.9 kgha-1 N was leached by drainpipes. In the treatment No. 4 with 150 kg N ha-1, 18.4 kgha-1 was leached through drainpipes. Out of 200 kg nitrogen added in treatment No. 5, 24.3 kg was leached, while the leaching in treatments 6, 7 and 8 amounted to 32.9, 23.4 and 28.4 kg, respectively. Out of the maximum 300 kg nitrogen applied for grown crops in treatment No. 9, an average amount of 33.6 kg nitrogen was leached through drainpipes. With its 11.2 kgha-1 of leached nitrogen, the last treatment &#8211 ; black fallow &#8211 ; ranks rather high, between treatment 3, in which 100 kg nitrogen was applied, and treatment 4, with 150 kg nitrogen.
