Opis:
The subject of the study was an analysis of the influence of two-component mineral fertilizers of Polish, Lithuanian and Russian production on the changes in the soil pH and the contents of available phosphorus and potassium as well as exchangeable magnesium after winter rape cultivation and the content of macroelements in winter rape seeds. The study also focused on the effect of using varying doses of fertilizers. A two-year field experiment was carried out on soil belonging 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. The applied two-component 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 the two-component fertilizers and potassium salt doses was reflected in a significant, but not proportional to the dose, increase in the amount of available phosphorus and potassium in the soil. While using fertilizers of Russian, Lithuanian and Polish production (POLIDAP®) during rape cultivation, there was no difference in the nitrogen, phosphorus, magnesium and sulfur contents in the seeds of cultivated winter rape of hybrid DK EXPLICIT cv.

Opis:
The subject of the study was an analysis of the impact of multicomponent mineral fertilizers manufactured in Poland and abroad, on changes in the content of available phosphorus and potassium as well as exchangeable magnesium in the soil. The study also looked at the effect of varying doses of multi-component fertilizers produced in Belarus, Russia and Poland. The experiments were carried out in 2015–2017 in Poland. The experimental plant was winter oilseed rape. The use of compound fertilizers of Belarusian, Russian, and Polish production did not have a significant impact on changes in soil pH during rapeseed cultivation. No differences in the effect of multicomponent fertil-izers on changes in the content of available potassium and ex-changeable magnesium were found. In the soils of both experi-ments, increasing the doses of tested multicomponent fertilizers had significant influence on the increase in the amount of avail-able potassium and did not cause any changes in the abundance of exchangeable magnesium in the soil. Generally similar effects of multicomponent fertilizers Belarusian, Russian and Polish origin on investigated soil properties were noticed.
