Abstract
The long-term dynamics of the anthropogenic soil solonetzicity under the impact of applied deicing salts were studied in the Eastern administrative okrug (EAO) of Moscow. The composition and amount of the applied agents and distribution patterns of sodium in snowmelt water and in soils of different land-use zones were analyzed. The maps of soil solonetzization in the EAO in 1989, 2005, and 2010 were compiled, and the degree of degradation of the soil cover was evaluated. It was shown that the contrast of the technogenic anomalies in the content of exchangeable sodium and the size of these anomalies in soils of the okrug increase with time. In 21 years, the mean content of exchangeable sodium in the surface soil layer increased from 0.38 to 0.80 cmol(equiv.)/kg, and the degree of solonetzicity (as judged from the exchangeable sodium percentage) increased from 3.1 to 7.2%. In 2005–2010, the rates of sodium accumulation in the soil adsorption complex were twice as high as those in 1989–2005.
