ABSTRACT, NaCO 3 -, NaSO 4 -, CaOH + , MgOH + . Calculation method is proposed for quantitative assessment of real ion forms in the soil solution of chestnut solonetz soil complex. Were proposed equations to calculate free and associated forms of ions. To solve the equations were used an iteration, a linear interpolation of equilibrium constants, a Method of Ionic Pairs including a law of initial concentration preservation, a law of the operating masses of equilibrium system, the concentration constants of ion pair dissociation on the law of operating masses. Was determined the quantity of ion free form and a coefficient of ion association as ratio of ions free form to analytical content γ e = C ass /C an . The association of ions varies in individual soils and soil layer. Increasing soil solution salinity amplifies the ions association. In form of ionic pairs in soil solution are: 11.8-53.8% of Ca 2+ ; 9.4-57.3% of Mg 2+ ; 0.7-11.9% of Na + ; 2.2-22.3% of HCO 3 -, 11.8-62.7% of SO 4 2-. The ion CO 3 2-is high associated, the share of ions in associated form is up to 92.7%. The degree of soil solution saturation was obtained for three level of approximation accounting on analytical concentration, calculated association coefficient, calculated coefficient of association. Relating to thermodynamic solubility product S 0 , the mathematical product of analytical ionic pairs indicated super saturation of soil solutions up to K 1 = 100, taking into account calculated coefficient of association ion activity super saturation of soil solutions is absent, K 3 ≈1. Only for solonetz chestnut meadow K 3 ≈2-5. The soil solution saturation degree in soil profile and laterally in landscape varies. The quantitative assessment of real ion forms in the soil solution allows explain evolution of landscape of salted soils, structure of soil cover. Calculations fulfilled show that a possibility of soil degradation scenario taking into account the laws of association of ions in soil solution is much more probable and dangerous than it was assessed before. New understanding of water-salt transfer, geochemical barriers and ecological functions of soil will help to improve rainfed and irrigational agriculture.

“…However, the saturation of the region with industrial objects significantly affected the microelement composition of the soil and plant cover and created ecological and toxicological risks (Heryati et al, 2011;Minkina et al, 2012). There are a large number of sites worldwide polluted with trace elements as a result of human activities.…”

Ordinary chernozems in the Azov Plain have a low background content of mobile zinc compounds, a sufficient supply with copper and an increased content of lead compounds. This specificity of the regional microelement composition is due to the high carbonate content in the soil profiles, the natural enrichment of littoral geochemical landscapes and the effect of the significant sources of microelement emission (Mariupol metallurgical enterprises, Novocherkassk regional power station, etc.). The high buffer capacity of soils in the Azov region significantly mitigates the negative effects of pollution.
