“…Cotton and other crops are well developed on the levelled lands. When machine-tractor units work on uneven fields, the traction resistance of the tool changes, resulting in reduced speed, increased vertical vibrations, which negatively affects the operation of the machine-tractor unit and increase the moisture content of the soil surface [20][21][22][23][24][25][26]. Therefore, high-quality levelling of the ploughed soil is required before the implementation of technological processes and surface irrigation in the cultivation of crops [1,2].…”

It has been proved in the world and our country’s agriculture that the levelling of arable lands helps the land to improve the reclamation of lands and reduce the amount of water for irrigation. According to agro-technical requirements, the height of irregularities on the surface of the fields should not exceed ± 5 cm. Experiments and research show that crop yields decreased by 1.5-1.7 times and irrigation water consumption increased by 1.7-3.4 times when the surface roughness of the fields was ± 10-13 cm. According to the research carried out by E. B. Velichko and B. B. Shumakova, in areas where the height of irregularities reached ± 3 cm, the yield increased by 1.5 times compared to ± 5 cm, and irrigation water decreased by 1.6 times. In areas with such unevenness of ± 2 cm, the yield increased by an additional 19.9 c / ha (47%), the consumption of irrigation water for the production of 1 ton of rice decreased by 36% or 1621 m3 of the economy was achieved.

A method for cleaning tanks from oil product residues based on biotechnology

et al. 2021

The known methods of cleaning tanks from the remnants of petroleum products using existing means are quite time-consuming, energy-intensive, and insufficiently advanced. In addition, waste cleaning solutions are poorly regenerated and slowly oxidized in the biosphere, and their removal to landfills (or discharge into reservoirs) causes great harm to the environment. Therefore, the search for new methods of cleaning is a very urgent task. This work aims to develop a method for cleaning tanks from the residues of petroleum products based on biotechnology. This article proposes a technological scheme of an experimental installation that simulates a tank for storing petroleum products in agricultural conditions. Studies on the oxidation of petroleum product residues by selected active cultures of microbial strains have been carried out. The modes of biological cleaning of the internal surfaces of tanks for the storage of petroleum products, from their residues, are determined. Strains of oil-oxidizing microorganisms were used as biologics). The biomass of the studied microorganisms was obtained under laboratory conditions by deep cultivation in flasks on a mineral medium. The proposed method of tank cleaning is an environmentally friendly process, during which microorganisms decompose oil pollution at relatively low temperatures (20-40°C) and use hydrocarbons as a source for their growth. As a result of this process, many tons of oil deposits are converted into microbial cells, which in turn become a source of food for other organisms and the plant world.

“…As a result, the number and type of equipment performing technological processes are increasing, and their entry and exit into the field correspondingly increase. This leads to compaction and deterioration of the structure of the soil, in addition to not meeting the requirements of resource conservation [16][17][18][19][20][21].…”

As the object of the research, the cotton stalk and its physical and mechanical properties, the elastic of the combined aggregate and the spherical disk were accepted. Like many other European countries, our country has also developed minimal, resource-saving and zero technologies for the cultivation of agricultural products, and their technical solutions are being supported and implemented by farmers and clusters. In particular, in the preparation of cotton fields for sowing for the next year in one pass of machinery in cotton growing, the research was conducted on the development of a minimum technology and a combined unit that implements it. In the implementation of this technology, the cotton stalks are tilted to the side furrow in the direction of movement of the aggregate, and the root is laid on the bottom of the furrow with the soil. The bottom layer of the existing pile is then divided into two parts, each of which is rolled over the cotton stalks on the side edges on both sides, where a new pile is formed. Once the aggregate has passed, the existing ridges are replaced by ridges with cotton stalks buried under them, and ridges are formed in place of the existing ridges. In the study, the angle of the axis of symmetry was determined by the angle of the stalks, and in the laboratory, the amount of force required to bend the stalks was determined using a specially prepared stand. In the study, the width of the flexible cover is 45 cm, the mounting angle of the straight part of the flexible relative to the direction of movement is 35-450, the radius of curvature should be 100 mm, the mounting height relative to the ridge should be 15 cm, and the shape was determined. Bending of cotton stalks standing on the ridge in the direction of aggregate movement to the side ridge, digging them with root soil, longitudinal laying at the bottom of this ridge can be done using a spherical disk.
