Multicomponent mineral fertilizers vs. soil abundance after sugar beet cultivation

The aim of the research was to analyze the impact on changes in the content of macronutrients in the soil after the cultivation of sugar beet, resulting from the application of mineral multicomponent fertilizers manufactured by Polish and foreign producers. The effect related to fertilizers of Belarusian, Russian and Polish production applied in different doses was also analyzed. The experiment was carried out in 2014–2017 in Lipnik. The experimental plant was sugar beet of NATURA KWS cv. Thestudies compared two factors: 1st factor – 3 multicomponent mineral fertilizers: Belarusian (A), Russian (B) and Polish, i.e. Polifoska (C); 2nd factor – 3 doses of fertilization (minimum, optimum, maximum, amounting to 2.0 4.0 and 6.0 dt per hectare, respectively). Fertilization with multicomponent fertilizers produced by Belarusian, Russian and Polish manufacturers did not change the pH of soil from experiment. In the experiment carried out, there was no diversified effect of multicomponent fertilizers of Belarusian, Russian and Polish origin regarding changes in the content of available phosphorus and available potassium in the soil, as well as exchangeable magnesium. The use of different doses of multicomponent fertilizers resulted in a significant increase in the content of available phosphorus and potassium in the soil.
