Sažetak
Nutrient transport down the soil profile, especially Nitrogen (N) varies considerably depending on soil properties and climate. Insufficient application of N fertilizer can result with the lower yield while excessive application of N could result by losses of it and pollutions. The consequences of N leaching to a deeper soil layers and subsurface water are manifesting as negative influence on human health and harmony of ecosystem. Field experiment was setup on trial fields of Agricultural Institute Osijek as split-split plot method in three repetitions during the period 2006 and 2008. Maize yield and pollution from N fertilizer were tested in irrigated and N fertilized condition with wide spread maize hybrid in Croatia, OSSK 552, created at Agricultural institute Osijek. For collecting the leachate Ebermeier's lysimeters were used. The leachate was analyzed in laboratory – the content of nitrate, nitrite and ammonium forms of nitrogen. Irrigation treatment was significant for both years of experiment with yield increasing for 13%, while the nitrogen fertilizer increased maize yield for 16%. Larger amount and concentration of leachate comes as result of irrigation intervals with the highest amount of water, fertilization with the larger nitrogen doses, and the highest amount of precipitation during vegetation season.
