俄语. В результате снижения объемов известкования за период 2009-2012 гг. наблюдаются нарастающие признаки подкисления пахотных почв в большинстве районов Беларуси. Обсуждается динамика содержания обменных форм кальция и магния в почвах, а также необходимость применения требуемых объемов известкования для поддержания оптимальных диапазонов реакции почв.

In course of the research there was realized a systematic analysis of the results of liming, distribution of arable and grassland soils in the regions of Belarus by groups of acidity in the period between the last two rounds of agrochemical inspection. The dynamics of the content of exchangeable forms of calcium and magnesium in the soil throughout the monitoring period was investigated. As a result of realized research there were revealed that as result of reduced application of lime during the period of 2009-2012 soil tests an increasing acidification of arable land in majority of districts of Belarus was indicated. Dynamics of calcium and magnesium supply in soils as well as the necessity for application of required volume of liming for maintenance of optimal reaction of agricultural soils were discussed.
