ИСТИНА

Paleocryogenic soil complexes were studied on gentle slopes 200 km east of Moscow. Ancient microrelief is now completely buried under agrogenically smoothed soil surface, but the sign of temperature differences between soils with different profiles is the same as it used to be long time ago, when these soils occupied different topographical positions. Lowest temperatures are typical for soils with low bulk density and high carbon content located in the areas of now buried paleomicrodepressions. Mathematical modeling proved that observed variability of soil properties is sufficient to explain lateral heterogeneity of soil temperature.
