ABSTRACT
The subject of the study was an analysis of the influence of two-component mineral fertilizers of Polish, Lithuanian and Russian production on changes in the soil reaction and contents of available phosphorus and potassium as well as exchangeable magnesium after winter rape cultivation and content of macroelements in winter rape seeds. The study also focused on the effect of varying doses of fertilizers used. A two – year field experiment was carried out on soil belongs to loamy sand, the IVa bonitation class. The experimental plant was winter rape, DK EXPLICIT hybrid. The experiment was established using random blocks design in 4 replicates. Two factors were compared in the studies: I. factor - 3 two-component mineral fertilizers of Russian, Lithuanian and Polish production (POLIDAP®). II. factor - 3 doses of fertilization (minimum, optimum, maximum, which were respectively: 1.0, 2.0, 3.0 dt per hectare). Introducing the two-component fertilizers and diversification of their doses was a factor that did not change the soil acidification. Applied two-components fertilizers (Russian, Lithuanian and Polish POLIDAP®) caused an increase in the amount of available phosphorus in the soil, with no differences depending on the fertilizer type. Diversification of doses of two-component fertilizers and potassium salt was reflected in a significant, but not proportional to the dose, increase in the amount of available phosphorus and potassium in the soil. Using fertilizers of Russian, Lithuanian and Polish production (POLIDAP®) during rape cultivation, there was no difference in nitrogen, phosphorus, magnesium and sulfur contents in the seeds of cultivated winter rape of hybrid DK EXPLICIT cv.
