Разработаны параметры почвенной и растительной диагностики магниевого питания кукурузы, ярового рапса и ячменя. Полученная информация позволяет подобрать поля и участки для дифференцированного размещения культур и выявить необходимость проведения некорневых подкормок растений 4%-ным раствором MgSO4 x 7H2О в зависимости от анализов почв и растений на ранних стадиях их развития.

The article deals with the analysis of experimental studies concerned the development of the parameters of soil and plant diagnostic of magnesium nutrition of agricultural crop for the lasr 10 years. 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 x 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 x 7H2О according to the analyses of soils and plants at early stages of their development.
