CHEMICAL METHODS FOR IMPROVING INFILTRATION PROPERTIES OF EXCESSIVELY MOISTENED ACID SOILS

Abstract

There are given results of model researches (in soil columns) into the effect of dolomitic meal, gypsum, and a combination of these ameliorants on changing infiltration and physical-chemical properties of excessively moistened gray forest heavy-loam soils in the Vladimir Opolye (Vladimir Region). In comparison with the control, when 300 mm of moisture (500 ml of water) passed through a column, the infiltration volume through gray forest soil was shown to increase from 151.6 to 193.0-224.9 ml, when applied both dolomitic meal, gypsum, and a combination of these ameliorants. A positive role of dolomitic meal is caused by decreased hydrolytic acidity of soil that reduces the peptization of soil colloids. The efficiency of dolomitic meal dose on full hydrolytic acidity made up about 50% that corresponded to the hydrolysis of ameliorant carbonate ions only on the first step. The equivalent gypsum dose to 1/3 of the hydrolytic acidity, as compared with dolomitic meal applied on the full hydrolytic acidity, increases the concentration of bivalent cations of calcium and magnesium in a liquid phase 3 times and more that provides coagulation of soil colloids as to the concentration mechanism. When 600 mm of moisture passed through a column with a full dose of dolomitic meal, its efficiency increased to 55%, and in case of its combination with gypsum (on 1/3 Ha) to 63%. The more reliable effect of infiltration speed increase is reached in the last variant. The variant with applying dolomitic meal in a dose of 1.5 Ha in combination with gypsum in a dose of 0.5 Ha has the longest action on preserving the increased infiltration speed.
