Sažetak
There is increasing concern about contamination of groundwater by nitrates in regions of intensive agriculture. The two-year lysimeter trial was set up in the Vrana basin in the Mediterranean region of Croatia with the aim to determine how the application of different mulching materials and drip-fertigation influence the leaching of nitrate in pepper growing. Green pepper cv. Istra F1 was grown for 2 years in a trial with three tretments: control without mulch, mulch of black polyethylene PE film and mulch of biodegradable cellulose film -biopack-, while an additional treatment with mulch of photodegradable transparent film was included in the second year. The rainfall in the growing period amounted to 390 mm in 1995 and 496 mm in 1996. The highest nitrate concentration was recorded in the percolate from the treatment without mulch. Total amounts of 20.45 kg N per ha and 18.77 kg N per ha were leached in the treatment without mulching in 1995 and 1996, respectively. 4.45 kg N per ha and 7.41 kg N per ha were leached under black film and biopack, respectively, in 1995, and 9.29 kg N per ha under black film and 12.96 kg N per ha under biopack in the following season. Large differences in quantities of nitrogen leached per trial treatments result also from the differences in plant lushness during the growing period as well as total crop yields. Mulching generally reduces infiltration of rainfall into the soil and thus leaching, resulting in relatively greater proportion of fertilizer to remain in the root zone.
