The effect of tillage methods on the cellulose-decomposing activity of the soil and on crop yields in crop rotations

In the conditions of Chuvash Republic in a long-term stationary experiment there has been studied effect crop rotations (grain- fallow and green manure) methods primary tilling soil (by plow PLN-3-35 to depth 24-26 cm; by combined unit KOS-3.0 14-16 disc header BDM-4-3.2 10-12 cm without autumn tilling) on cellulose-decomposing activity method setting up flax linen yield. The article provides 2016-2020 data. It established that plowing increased total porosity (55.3…63.5 %) provided maximum decomposing (42.9…51.3 %). Absence led statistically significant decrease (50.8…59.3 (36.1…43.9 Maximum yield crops rotation was obtained cultivation according traditional plowing. When replacing subsoil tillage use stubble cultivator best variant. Primary using instead 0.29 t/ha) spring vetch only. Among other cultures no decrease. Complete rejection 16-25 % loss grain crops. Plowing arable layer (24-26 cm) as fertility indicators dark-gray wooded (its porosity, activity) rotation. But when changing over resource saving technologies for under should be used.
