THE DYNAMICS OF BUFFERING OF LEACHED CHERNOZEM IN NORTHERN FOREST STEPPE ZONE OF THE CHELYABINSK REGION WITH LONG-TERM IRRIGATION [№ 12 ' 2017]
Buffering acid is one of the most important integral characteristics, which allows to evaluate the resistance of soils to acidification. Issues associated with its assessment have become increasingly important due to progressive acidification of soils in some regions of the planet under the influence of natural and anthropogenic factors. Currently, soils of the Chelyabinsk region is subject to high anthropogenic load, especially on black earth soil in long-term agricultural use. Scientists found that soils in long-term agricultural use subject to degradation processes, resulting in change of water-physical, physical-chemical and agrochemical parameters of soils. The paper studied the dynamics of the size of buffering in the acidic pH range of leached Chernozem in Northern forest steppe zone of the Chelyabinsk region in terms of long-term irrigation. The amount of buffering substances of acidic character were determined by the method of Arrhenius. As a quantitative measure of the buffer.
