摘要：
The long-term and seasonal dynamics of the potassium status of leached, typical, and ordinary chernozems, depending on hydrothermal conditions and fertilization, were examined in the Republic of Bashkortostan. The character of changes in the potassium regime of cultivated soils was shown; the rate of decrease in the content of exchangeable potassium and the fertilizer expenditures for its sustenance were determined.
