Abstrakt:

Simultaneous application of nitrification inhibitors and nitrogen fertilizers (containing reduced forms of nitrogen (ammonium and urea) can increase soil acidification caused by these fertilizers. As a result, it can lower soil reaction (pH) and influence the content of available forms of heavy metals and trace elements. The aim of the study was to evaluate the  effect  of  the  application  of: ENTEC-26  (containing  3.4-dimethylpyrazol  phosphate /DMPP/ – nitrification inhibitor) and ammonium nitrate on the mineral composition of carrot  storage  roots. A two-year  research was conducted  with  field  cultivation  of  the  carrot cultivar Kazan F1. The experiment was arranged in a split-plot design with four replicates. The  following  combinations  with  different  N  fertilization were  distinguished: 1 – control (without N fertilization), 2 –  ENTEC-26  35+35,3 –  ENTEC-26  70+70,  4  –  ENTEC-26 105+105, 5 – ammonium nitrate 35+35, 6 – ammonium nitrate 70+70,7 – ammonium nitrate 105+105, where: 35+35, 70+70 and 105+105 denote nitrogen doses (kg N ha–1)  used for preplant fertilization and top-dressing, respectively. In carrot storage roots as well as in soil after carrot cultivation, concentrations of Ag, Al, B, Ba, Ca, Ce, Co, Cr, Dy, Fe, Ga, In, K, La, Li, Lu, Mg, Mn, Na, Ni, P, Pb, S, Sc, Sn, Sr, Ti, Tm, Y, Yb and V were determined using the ICP-OES technique. Nutrition with nitrogen had significantly influenced the content of Co, Fe, In, Li, Mn, Ni, S, Sc, Sr, Y, Yb and V in carrot roots and this effect varied depending on the type of fertilization regime used in the experiment. No significant impact of N fertilization was found in reference to the accumulation of Ag, Al, B, Ba, Ca, Ce, Cr, Dy, Ga, K, La, Lu, Mg, Na, P, Pb, Sn and Ti in carrot roots. In relation to the control, application of all doses of both ENTEC-26 and ammonium nitrate resulted in decreased concentration of Mg, Al, B, Ba, Ce, Fe, Ga, La, Ni, Pb, Ti, Y, V, Cr, Dy, In, Li, Lu, Sc and Yb as well as enhanced accumulation of Ca, Sr and Ag in soil after carrot cultivation. Nonetheless, the above changes in the concentration of elements in soil due to N fertilization were not reflected in their levels detected in carrot storage roots.
