The work sums up and briefly discusses solutions of soil tillage minimisation technologies and machinery, their agronomic, energetic, mechanic, economical and ecological aspects. Tillage minimisation is performed in directions: reducing number of passes, as well as tillage depth and intensity, joining operations, improving machine design and aggregation, using advanced more suitable technologies and machines, conducting tillage in optimal terms. Minimization of soil tillage is agronomically acceptable, energy, labour and cost saving action. Improvements in the machine design and use for the traditional soil tillage technologies allow to save 24- 36 % of energy (46-110 kWh/ha, which corresponds 12-27 kg/ha of fuel), to reduce labour consumption by 16- 22 %, as well as to cat tillage costs by 14-26 % (10-20 USD/ha). Soil tillage minimisation with ploughing reduces these indices up to two times, without ploughing – up to six times. Besides these actions there is preservation of soil and environment.

Analyzing a number of scientists’ research on development of disk tillers, working units of which make a complex spatial motion, we proposed the construction of rotary implement, which contains the elliptical wheels, fixed to the battery shaft is strictly at a certain angle. The article presents the structural scheme of this tool and theoretical dependences for the determination and justification of its basic parameters. The technical solution allows to mutually balance the axial loads, provides uniformity of soil tillage depth, improves the technological stability of instruments and the effectiveness of its work.

Tillage Depth

The influence of agricultural methods and soil and climatic conditions on soybean cultivation in the southern regions of the Amur Region was researched. Schemes of two-factor experiments to study the effectiveness of deepening the arable layer of soil during crop cultivation in 2014–2016 included the following options. Factor A – tillage: autumn – disk plowing or cultivation; spring disk plowing or cultivation; summer – inter-row cultivation with or without para-plowing. The options were combined in different ways, whereby the option of soil tillage with a disc harrow in autumn and spring was taken as control. Factor B: sowing with seeders SZ-5.4 and SP-3.6 L with row spacing (options – 15, 45 and 60 cm) with various tillage systems. In 2017–2018 experiments were carried out according to the following schemes. Factor A – tillage: in autumn tillage depth at 0.12 m with a disc harrower PM-8; in spring, before sowing – at 0.10 m (cultivator Case Tiger Mate 225 – control); autumn – tillage depth at 0.28 m (cultivator Lemken Karat 9/400); spring, before sowing – at 0.10 m (Case Tiger Mate 225). Factor B – seeding units included Amazon DMC 9000 (control); Amazon DMC 1200, Case Pro Disk 500 AFS, John Deer 1890, Lemken Solitair 12, Horsch Pronto 9 DC, Tom’ 12, SP-3.6 L. Deep autumn cultivation, in contrast with disk plowing, ensures a more favorable waterair regime for plants and an increase in soybean yield. Seeding units Case Pro Disk 500 AFS, John Deer 1890, Amazon DMC 9000 and SP-3.6 L used in combination with Lemken Karat 9/400 + Case Tiger Mate 255 machines for deepening the arable layer provided an increase in soybean yield by 25.0–38.3% compared to soil tillage with discs. It is recommended to use wide-span seeding units for soybean cultivation in large and medium-sized farms in fields with subdued relief in accordance with high-intensity technology. It is advisable to use SP-3.6 L seeder with a seed shoe for organic crop production in small-scale agricultural enterprises.

The authors have described the required conditions for uniform soil tillage at a given depth. It has been shown that depth wheels of tillage machines should be constantly pressed to the soil surface. The study has confi rmed the need to determine the optimal value of the vertical pressure force exerted by the depth wheels on the soil. (Research purpose) To determine ways to ensure the given depth of tillage and the required uniformity using a mounted plow with a depth wheel. (Materials and methods) The authors conducted theoretical studies using methods of theoretical and agricultural mechanics, as well as analytical geometry. They made a diagram of forces acting on the plow in the process of plowing. (Results and discussion) The authors obtained an analytical relationship to determine the vertical pressure force exerted on the soil by a depth wheel of a mounted plow taking into account dimensions and parameters of a tractor mounting system as well as a plow mounting linkage. The optimal values of vertical distance from the plow supporting plane to its lower connecting points were graphically determined. The authors calculated the optimal numerical values of the parameters taken into account: the vertical distance from the tractor's supporting plane to the attachment point of the lower links of its attachment mechanism is 0.6 meters; the number of bodies installed on a plow – 4; the weight of one plow body is 250 kilograms; the plow effi ciency – 0.7; plowing (tillage) depth – 0.3 meters; horizontal distance from the lower connecting points of the plow to the share point of the fi rst body – 0.45 meter; longitudinal distance between the plow bodies – 1.0 meter; plow landside width – 0.2 meters; coeffi cient of rolling resistance to the depth wheel of the plow – 0.2; the diameter of the depth wheel – 0.5 meters etc. (Conclusions) It has been established that in order to ensure a required plowing depth and uniformity, vertical distance from the supporting plane of four-body plows coupled with 3-4 class wheeled tractors to the lower connecting points should be within 0.703-0.771 meters.

Soil tillage, like making raised beds, is time-consuming and labour-intensive if it is done without the help of mechanization. Therefore, this study aims to develop and test a bed former powered by a hand-tractor for upland. It was carried out in the experimental field (sandy clay loam texture) at a furrower depth of 15 cm and 20 cm with a tractor forward speed of 0.5 m/s. The bed's former design results have dimensions of length, width, and height of 1200x1000x 820 mm. The performance test results showed an increase in tillage depth resulted in increased bed height, bed width, bed width, and slip. However, field capacity decreases with increasing tillage depth. The bed former's performance was found to be satisfactory in general.
