Abstract
Description
The aim of the research was to test of several vari-
ants of basalt-sulphur improver, differing in the ratio of the two
components, and to select the most suitable one for oilseed rape.
Basalt dust, which is a troublesome by-product of rock process-
ing, and elemental sulphur were used to produce the improver.
The study included 3 improver variants with 1, 1.5 and 2% S and
a control treatment without an improver. The experiment was
conducted in concreted microplots filled with two soils: sandy
loam and loamy sand, in a split-block two-factor design, in
4 replicates. The most suitable variant for rapeseed was the vari-
ant containing 1.5% S, which resulted in a 12% increase in rape-
seed yield on sandy loam. Moreover, for this variant, an increase
in seed fat content, an increase in the bioavailable form of sulphur
in the soil and an increase in the concentration of this nutrient in
oilseed rape straw and seed were observed on both soils.
