| Abstract | In 2003–2005 in carrot cultivation the following combinations were applied (kg N ha): 1 – Control (without N fertilization), 2 – calcium nitrate 70, 3 – calcium nitrate 70 + 70, 4 – ammonium sulphate 70 and 5 – ammonium sulphate 70 + 70; where 70 means 70 kg N ha was used preplant, whereas 70 + 70 that 70 + 70 kg N ha was applied preplant and as a top dressing, respectively. In the individual years of the research a diversified effect of nitrogen fertilization on the content of NH4-N, NO3-N, Cd, Cu, Pb and Zn and soil reaction (pH) after carrot cultivation, as well the size of changes in these chemical characteristics in 0–30 cm and 30–60 cm soil layers were noted when compared with the values measured prior to the start of carrot cultivation. Variable climatic conditions as well as rainfall amount and its distribution significantly influenced the content of mineral nitrogen in 0–30 and 30–60 cm layers of soil after carrot cultivation. In 2003, characterized by the lowest rainfall in the period of carrot cultivation and drought in the summer months, were noted the highest content of NH4-N in 30–60 cm layer of soil fertilized with presowing and topdressing treatment of ammonium sulfate, and NO3-N in 0–30 cm layer of soil fertilized with presowing and top dressing treatment of calcium nitrate. |
