“…Согласно исследованиям Е. Х. Нечаевой с соавт. [7], интенсивность разложения волокон целлюлозы снижается при поверхностной обработке почвы по сравнению с глубокой основной. Объясняется это тем, что основная часть микроорганизмов, способных переработать целлюлозу, является аэробами, а при поверхностной обработке степень аэробности почвы снижается.…”

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

Soil fertility is largely determined by the intensity and direction of enzymatic reactions. All biological processes associated with the transformation of substances and energy in the soil are carried out with the help of enzymes that play an important role in the mobilization of plant nutrients, and also determine the intensity and direction of the most important biochemical processes associated with the synthesis and decomposition of humus, hydrolysis of organic compounds and oxidative - the restorative regime of the soil, therefore, the enzymatic activity of the soil can be used as a diagnostic indicator of soil fertility under various types of anthropogenic load. The influence of the methods of basic soil cultivation on the enzymatic activity of ordinary chernozem in winter wheat crops during its cultivation on a pure and green manure fallow in the conditions of the Middle Volga region has been studied. According to the results of the studies, the highest catalytic activity of ordinary chernozem in winter wheat crops for the studied enzymes (urease, invertase, catalase, peroxidase and polyphenol oxidase) is confined to the 0-20 cm layer and is explained by the abundant location in it of the “living” root mass enriching the upper soil layer biologically active exudates that stimulate the development of microflora and activate enzymatic activity. Favorable conditions for the humification of plant residues and the accumulation of humus-like substances are formed when green manure fallow is included in the crop rotation and used as the main soil cultivation without loosening by 10-12 cm.
