Grassland stress effect on the macroelements dynamics in soil-plant system

[摘要] High rate of litter mineralization in steppe and forest-steppe zones facilitates litter macroelements release and their involvement in open cycles with further migration through the soil profile. Grassland stress initiates mineralization processes that enable macroelements to get rapidly involved in the process of organic matters re-synthesis. Grassland transferring into reserve state leads to litter accumulation in upper soil layer and degradation processes to slow down.
