Abstract The experiment is carried out in the conditions of semi-desert flat agricultural landscapes of light chestnut soils. The object of research is a 4-field crop rotation (factor A), variants of the main tillage (factor B) and crops superimposed on the tillage options with the Don-114 seeder (a seeder for direct sowing). The placement of options (A) is sequential and options (B) are arranged in blocks in three tiers. The main soil tillage was carried out by the following tools: mouldboard tillage to the depth of 25-27 cm by plough PN-4-35; non-mouldboard tillage to the depth of 25-27 cm by the tool OCHO-5-40 with the rack “Rancho”; surface one to the depth of 8-10 cm by the tool BDM-4.2, and 4-field grain-fallow crop It was found that a higher content of nutrients is in fallow preferably at non-mouldboard soil treatment, in some years, which has an optimal moisture supply, and control (mouldboard) one in comparison with lower levels of surface soil treatment in all years of the research. The main comparison in the change in nutrients in fallow fields is observed precisely for different methods of soil cultivation.

Strip Tillage

Abstract The article highlights the results of research in strip farming. The method of minimum soil tillage, a resource-saving working body ROPA and a soil tillage tool for strip ripping OMPO-5.6, which are designed to perform fine soil tillage with strip deepening, are proposed. Adjustment of loosening depth from bit is achieved within the range of 0.25-0.4 m and is selected taking into account the crop grown in the farm. Availability of undercutter tine allows to regulate parameters of continuous ripping zone. Parameters of treated and untreated strips are regulated by location of undercutter paw. The design of the tool provides a smooth adjustment mechanism by which the width of the cultivated strip can be changed within 0.25-0.35 m. This makes it possible to use the implement for different tilled crops. The technological process carried out by this working body helps to reduce the wounding effect on the soil through a simple technical solution. Installation of side undercutting discs allows cultivating the soil within a given strip, and the process of cutting the soil in a blocked environment improves the quality of treatment.

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.

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.

Abstract The paper provides the simulation results of a small-diameter guided training bomb released during atmospheric turbulence. The simulation utilized a guided bombed devised at ITWL. Aerodynamic characteristics of the bomb were obtained from wind tunnel tests and from calculations made by the PRODAS programme. The simulation programme was developed based on a mathematical model describing a spatial motion of an aerial bomb moving in atmospheric turbulence. To describe a turbulence component, the model of stochastic processes proposed by Shinozuki was used. The manuscript includes examples of diagrams of basic parameters showing the bomb flight in a disturbed atmosphere. The analysis of the impact of the standard deviation of the wind on the change in the parameters of bomb flight was performed. The relationships between the parameters of bomb flight and the possibility to hit the target were provided.
