Effect of basalt dust application with sulfur addition on soil pH and nutritional value of wheat and pea

The microplot experiment was carried out on two soils (clay and sandy) with spring wheat and fodder pea. In the experiment, the effect of a granular product made of basalt dust and elemental sulphur with a sulphur content of 1.5% was tested. Fertilization of wheat with sulphur in the dose of 30 kg/ha S and pea in the dose of 20 kg/ha S in the form of basalt-sulphur granulate resulted in a significant increase in the content of methionine, cystine and protein in wheat grain on sandy soil. However, no increase in the content of these amino acids and protein in pea seeds was observed. Moreover, an increase in the content of sulphur in wheat grain and straw as well as in pea straw was noted. The use of sulphur in combination with basalt dust did not lower the pH of any of the experimental soils.
