“…The content of humus in the arable layer of the soil of the experimental plot in the northern forest-steppe of the Kuznetsk basin was 8.2%, phosphorus (according to Chirikov) was 14.3 mg/100 g of soil, exchangeable potassium (according to Chirikov) was 13.4 mg/100 g of soil, Salt pH was 6.0, granulometric composition was heavy loamy. The studies were carried out in grain-row crop rotation (barley with oversowing of clover (minimum tillage) -cloverwheat (zero tillage) -potato), as well as in grain-fallow (pure fallow (green manure fallow)wheat -peas -pure barley and barley with overseeding of sweet clover) using various tillage systems for crops: moldboard deep (moldboard plowing in autumn), combined deep (nonmoldboard deep in autumn), combined minimum (non-moldboard shallow in autumn), mulching minimum (direct sowing without tillage) [20,21].…”

The materials of long-term field experiments carried out in the forest-steppe of the Ob region of the Novosibirsk region and in the northern forest-steppe of the Kuznetsk basin of the Kemerovo region in various types of crop rotations on leached chernozems were analyzed to assess the possibility of developing organic farming. The most stable crop rotation in relation to weeds is a grain-fallow crop rotation with winter rye, where the coefficient of crop rotation productivity decrease with an increase in infestation by 1 unit of specific weed biomass was 0.205.The number of interstim pests per plant was less on wheat crops placed on vetch-oats, winter rye and rapeseed than on fallow and spring grain predecessors. The most productive crop rotations without the use of fertilizers and pesticides were grain fallow crop rotations with winter rye (2.46 t/ha) and legumes (2.44 t/ha). It has been established that organic farming can only be carried out under conditions of crop diversification (increase in biodiversity within crops of winter rye, cabbage, leguminous grasses and grain legumes), a decrease in the intensity of mechanical impact on the soil, the introduction of organic fertilizers and plant residues of crops, sideration.

The authors showed that a rotary plow deepened the arable layer and destroyed the plow bottom, simultaneously crushed plant residues, green manure crops and embedded them in the soil upper layer that was active for the cultivated plants roots and microorganisms, which allowed providing them with available nutrients, maintained fertility and increased soybeans yield.(Research purpose) To determine the soil deepener and the plow rotor agrotechnical parameters when working after different predecessors, to establish the dynamics of nutrients, soybean yield and to compare the technical indicators of various tillage implements.(Materials and methods) The authors studied rotary plow indicators when cultivating the soil after green manure, wheat and soybeans: the tillage depth and the tooth linear speed, the rotor rotational speed and depth, crumbling, hardness and ridging of the soil surface, the presence of plant residues, specific fuel consumption, productivity. They conducted a comparative field experiment, meadow-chernozem-like soil was treated with tools: discs BDT-3.0 – control; plowshare PLN-3-35 and rotary plow PRN-2.5 M.(Results and discussion) The authors determined that the tillage depth with the rotor was 0.143-0.149 meters, with the soil deepener – 0.25 meters, 25-27 percent of crop residues remained on the soil surface. It was found that the rotary plow details provided good soil cultivation, as a result of the incorporation of stubble and green manure, they contributed to a content increase of phosphorus in it by 11.8-13.3 percent, potassium – by 18-21.8, nitrogen – by 48.1-48.9 percent, which had a positive impact on the soybeans yield.(Conclusions) The authors found a regular increase in soybean yields when processing the soil with a rotary plow by 0.32 tons per hectare compared to discs and by 0.06 tons per hectare compared to a share plow. It was suggested to use a rotary plow PRN-2.5 M. for soil cultivating for soybeans in the Amur region. They calculated the economic and energy feasibility of soil cultivating with a rotary plow in organic crop production.

Evaluation of agroeconomic efficiency of different tillage systems for mustard, cultivated in a grain fallow rotation with the following alternation of crops: complete fallow - winter wheat – spring wheat - mustard is presented. The experiments were made in a field experiment in the forest-steppe zone of the Middle Volga region in 2019-2021. The soil of the experimental plot is slightly leached medium-powered heavy loamy chernozem. Tillage horizon is characterized by the following agrochemical parameters: humus content of 5.8 to 6.1%, the provision of mobile phosphorus is high (226 mg/kg), the potassium is medium (92 mg/kg), the reaction of the soil solution is close to neutral (pH 6.6). The object of the study is the mustard variety Rhapsody, the subject of the study is soil tillage systems. The expediency of replacing the annual classic plowing with a differentiated treatment in the rotation, based on the alternation of deep plowing and surface disc cultivation is established. It positively affects the process of formation of agrophysical, biological and agrochemical properties of soil, contributes to the conservation of productive moisture reserves, and helps to reduce weed infestation of crops. This treatment leads to a significant increase in the yield by 0.11 t/ha, allows for the highest yields of 199% (on average for the backgrounds) and the highest energy factor of 1.33, which is 71 and 22% higher than on the option with the annual mouldboard plowing. It was noted that the used mineral fertilizers at a dose of N30P30K30 did not produce the desired effect. Lack of yield growth led to the formation of negative economic indicators when making mineral fertilizers in all the variants studied, with the exception of differentiated treatment in the rotation. In this variant, the maximum increase in the yield by 0.25 t/ha and the cost of gross output by 7500 rubles/ha, which is 1521 rubles/ha higher than the increased production costs is noted. In the option with annual mouldboard plowing fertilization was accompanied by a decrease in the net income and profitability levels by 965 rubles/ha and 75% relative to the non-fertilized background, indicating that the unprofitable use of fertilizers.
