DIAGNOSTIC OF THE CROP MAGNESIUM NUTRITION ON PODZOLUVISOL LOAMY SOILS

Abstract

The results of long-term field experiments on specially prepared 4 levels of exchangeable magnesium content in Podzoluvisol loamy soils in a wide range of Mg 46–263 mg · kg–1 are presented. The parameters of soil and plant diagnostics of magnesium supply of corn, spring rapeseed and barley have been developed. The obtained data enable to choose the appropriate fields for particular crops and to identify the necessity for foliar spray of plants with 4 % solution of MgSO4 · 7H2О according to the analyses of soils and plants at early stages of their development.
