Short summary
This study set out to determine the quantity of organic carbon (OC) which is protected from microbial decomposition in macro-aggregates of Siberian steppe soils under different land use. Our results imply that the quantity of macro-aggregate protected OC is smaller than in similar steppe ecosystems like the North American prairies. We conclude that the tillage-induced breakdown of macro-aggregates after grassland to arable land conversion has not reduced the OC contents in the studied soils.
