Sažetak
Nowadays, when the negative impact of nitrogen fertilization is recognized, requisites are arising to determine the actual contribution of specific agricultural practices on environment degradation. Isotope analyses are imposing as key techniques for confirmation of nitrogen origin in soil and agricultural impact on ecological footprint of nitrogen on environment. Main objectives of this research were: (a) to determine soil δ15N isotope content regarding the variable doses of nitrogen fertilization and soil depth ; (b) to determine δ15N isotopic signature in applied commercial nitrogen fertilizers. Research was based on 12 soil samples and 9 fertilizers [urea, granular and piled LAN (limestone ammonium nitrate) and six NPK fertilizer formulations]. Soil samples were collected from a stationary field experiment in 2018 located in central part of Croatia after 22 years of application variable nitrogen doses (0, 100, 200 and 300 kg N/ha) on three depths (0-30, 30-50 and 50-80 cm). Analyses were performed in 2021 in two replications and δ15N isotopes in soil and fertilizers were determined by the EA-IRMS method. The results reveal that variability of the δ15N isotope content in soil (+5.1 ‰ to +7.7 ‰) indicates the organic origin of nitrogen in the soil despite the long-term application of mineral nitrogen fertilizers. As a confirmation of this allegation the range of δ15N values in the applied nitrogen fertilizers was from -0.96 ‰ in piled LAN up to +3.26 ‰ in NPK 7-20-30, implying that observed fertilizers were produced by processes of "industrial" fixation of atmospheric nitrogen and they did not leave a mark on the total nitrogen in the soil.
