    A wide range of multicomponent fertilizers, often with similar chemical composition, differs in the quality and digestibility of nutrients and price. The paper compared the effect of mineral multicomponent fertilizers from Polish and foreign producers on changes in the content of macronutrients in soil during sugar beet cultivation. The study also analyzed the effect of varying doses of fertilizers used. Fertilizers used were characterized by the following composition of NPK(S): two Belarusian 8–20–30, Russian 7–8, 19–20, 29–30 and Polish 6–20– 30(7) – Polifoska 6. The experimental plant was sugar beet of NATURA KWS cv., normal-sugar type. The soil on which the experiment was carried out was characterized by low abundance of available potassium and medium available phosphorus and exchangeable magnesium. The experiment was carried out in 2014–2017 in Lipnik. The study compared two factors: 1st factor – 4 multicomponent mineral fertilizers (two Belarusian, one Russian and Polifoska). 2nd factor – 3 doses of fertilization (minimum, optimum, maximum, which amounted to 2.5, 5.0 and 7.5 dt per hectare, respectively. Fertilization with multicomponent fertilizers did not have a significant impact on changes in the pH of experimental soil. In the experiment carried out, there was no difference in the performance of tested multicomponent fertilizers: Belarusian, Russian and Polish, regarding changes in the content of available phosphorus as well as available and exchangeable magnesium in the soil. The use of different doses of multicomponent fertilizers resulted in a significant increase in the content of available potassium and exchangeable magnesium in the soil, and the available phosphorus after using the highest dose of fertilizer.
