Multicomponent mineral fertilizers vs. soil abundance after sugar beet cultivation

Abstract

When choosing a multicomponent fertilizer, apart from chemical composition and mutual proportions between components, agrotechnical factors should be taken into account. When using multicomponent fertilizers, the fertilizer best suited to the nutritional needs of plants and existing soil conditions should be selected from the entire range of available products. Analysis of economic effectiveness of fertilization is also important. The aim of the research was to analyze the impact on changes in the content of macronutrients in the soil after cultivation of sugar beet, resulting from applying the mineral multicomponent fertilizers of Polish and foreign producers. The effect of different doses of applied fertilizers of Belarusian, Russian and Polish production was also analyzed. The experiment was carried out in 2014-2017 in Lipnik. The experimental plant was sugar beet of NATURA KWS cv. Studies compared two factors: 1st factor - 3 multicomponent mineral fertilizers: Belarusian (A), Russian (B) and Polish, this is Polifoska (C); 2nd factor - 3 doses of fertilization (minimum, optimum, maximum, amounting respectively to 2.0 4.0 and 6.0 dt per hectare). 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.
