PECULIARITIES OF SOIL FORMATION IN FOREST-STEPPE ZONE DEPENDING ON THE AGE AND MOTHER ROCK
217 KB
Soils in ditferent conditions of the substrates and coenoses of a forest-steppe zone on three settlements of various archaeological cultures have been studied that has allowed to generate a chronological number of soils age: n 1000 years, where n=1, 2, 4. Using duration of time which is necessary for physical and chemical properties of soils for approach to zone values, ranked a number of indicators (from most quickly reproduced to more conservative) has been defined: C:N> рН> P2O5> the sum of the absorbed bases> the humus content > total nitrogen. Such indicators of soil properties come nearer to zone conditions already at age of soils of 1000-1500, as the humus content, nitrogen and phosphorus, the sum of the absorbed bases, parity C:N. Dependence of the content of organic carbon, a share of its labile part on time is characterized by natural increase in values of these indicators up to 2300. In forest-steppe conditions the vegetation type under which the soil develops, has not smaller value, than its age.
