Sažetak
Excess application of nitrogen fertilizers in agricultural systems leads to nitrate accumulation in deeper soil layers which can result with groundwater contamination. These environmental issues impose the need for better understanding of the role and the fate of nitrogen in soils. Temporal and spatial nitrate distribution was determined at different nitrogen fertilization levels during maize and winter wheat vegetation period. Nitrates in soil extract were separated by Doinex ICS-1000 system. Results indicated that maize and winter wheat influenced soil vertical nitrate distribution differently. Ion chromatography method is a recommended method for nitrate detection in soil extracts because of many advantages that it offers, particularly high rapidity and simultaneous detection.
