METHOD OF DETERMINING EFFICIENCY OF TYPES OF POTASH FERTILIZER ONTO SOD-ASH SOIL

摘要

FIELD: agrochemistry; soil science. SUBSTANCE: different types of potash fertilizers are introduced into soil. Two weeks later soil samples are selected, and specific surface of the samples is determined. The most efficient type of potash fertilizer may be considered such a type, which has the most high specific surface factor. EFFECT: improved efficiency. 2 tbl
