Kharitonov G.V., Manucharov A.S., Pochatkova T.N., Tyugay Z. EFFECT OF SOLUBLE SALTS ON THE SURFACE PROPERTIES OF CLAY MINERALS [№ 4 ' 2011] Shown that the effect of soluble salts on the surface properties of clay minerals depends on the nature of the mineral properties of salt used and its state (in solution or adsorbed). Processing of clay minerals with solutions NaCl, MgCl2, Ca(CH3COO) 2 and ZnCl2 leads to an increase in their water-holding capacity according to the following series: NaCl > MgCl2 > Ca(CH3COO) 2 ≈ ZnCl2.
Nikolaeva I.V., Pochatkova T.N., Manucharov A.S. INFLUENCE OF LONG TIME USAGE OF FERTILIZERS ON RHEOLOGICAL PROPERTIES OF TYPICAL CHERNOZEM [№ 12 ' 2007] The analysis of rheological curves of typical chernozem at humidity of maximal swelling allowed revealing that manure application caused dilatant properties at the expense of soil aggregates water-stability increase. Specific capacity increase of maximum destruction of structure in variant with manure improves technological properties of soil at the expense of viscosity decrease and durability limits increase. Under influence of mineral fertilizers sharp decrease of specific capacity of maximum destruction of structure in comparison with control is happened which causes unfavorable structural-mechanical properties.
