The aim of the research was to test of several variantsof basalt-sulphur improver, differing in the ratio of the twocomponents, and to select the most suitable one for oilseed rape.Basalt dust, which is a troublesome by-product of rock processing,and elemental sulphur were used to produce the improver.The study included 3 improver variants with 1, 1.5 and 2% S anda control treatment without an improver. The experiment wasconducted in concreted microplots filled with two soils: sandyloam and loamy sand, in a split-block two-factor design, in4 replicates. The most suitable variant for rapeseed was the variantcontaining 1.5% S, which resulted in a 12% increase in rapeseedyield on sandy loam. Moreover, for this variant, an increasein seed fat content, an increase in the bioavailable form of sulphurin the soil and an increase in the concentration of this nutrient inoilseed rape straw and seed were observed on both soils.
