Evolution of chernozems in the southern forest-steppe of the Central Russian upland under long-term cultivation examined in the agro-chronosequences

Chernozems are the major component of soil cover in the forest-steppe of the Central Russian Upland. From our point of view, the best way to observe the effect of ploughing on Chernozems is the examination of soils with different durations of cultivation based on an agrochronosequence approach which was used in this stud
