Basic soil cultivation and the humus status of dark-grey forest soils of the Northern Trans-Urals

, : Basic soil cultivation and the humus status of dark-grey forest soils of the Northern Trans-Urals. Zemledelie ( 5): 8-9

Long-term cultivation of the dark-grey forest soils of the Tyumen region has reduced their average humus content. The properties of these soils are optimum at a humus content of 6-8%. Four different methods of basic tillage were compared on a heavy clay-loam dark-grey forest soil, viz. mouldboard ploughing, non-mouldboard ploughing, combined tillage, and minimal cultivation. The soil was used for a fallow-winter rye-wheat-peas-barley crop rotation.
