The purpose of the research was to determine the material, energy and other indicators for the cul-tivation of crops of the crop rotation link using fertilizers, pesticides and effective growth stimu-lators for different-depth basic soil treatment. It was found that the crops of the grain-tillage rota-tion link, which were cultivated by plowing to a depth of 22-24 cm (control), surface treatment to a depth of 6-8 cm and zero (chemical) treatment significantly changed their productivity, and also formed various production, and therefore energy costs. The yield of oilseed flax was 1.70 t / ha, winter wheat-6.23 t / ha, mogar grain of crop sowing-0.49 t / ha, mogar hay-1.74 t / ha, peas-3.86 t/ha. The yield of these crops obtained using the no-till technology was, respectively, at 12- 3- 0 – 4 the percentage is lower than in the control. The largest net income (64090 rubles / ha), the amount of additional energy (220998 Mj) and the energy efficiency coefficient (3.5) were formed during surface tillage for crops of the crop rotation link, including due to the mogar of crop sow-ing, respectively 3370 rubles/ha and 243208 Mj. Cultivation of 4 field crops in 3 agricultural years significantly increases the economic and bioenergetic efficiency of production and can be applied in other regions.

The development of resource-saving tillage and direct seeding technologies (no-till) of field crops end up making a profit when it is based on the results of research and practice but this is not the case in all regions. Taking this into account, in the central zone of the Krasnodar Region in the permanent crop rotation from 2013 through 2018, we studied the integrated effect of plowing (22-24 cm -the control), surface tillage (6-8 cm) and zero tillage (herbicide treatment) and the crop in the rotation on the economic efficiency of production and elements of soil fertility. The average annual air temperature in the area is +12.1°C; the precipitation amount is 614 mm. The soil is represented by ordinary chernozem; humus amount in the arable layer makes 3.8%; P2O5-22-28 mg kg of soil; K2O -350-380 mg kg of soil (according to B.P. Machigin). The accounting area of the plots amounted to 5000 m2; fourfold plot replica-tion; threefold temporal replication. The crops were sown with the Rapid600 seeder with fertilizer application. Pesti-cides and growth promoters were used. The crops were harvested with a Claas Tucano combine harvester. It was found that the tillage variants affected the yields of crown flax, winter wheat,foxtail millet in stubble field, and field pea; and also changed the production costs and the condi-tional net income for crops and the course of the crop rota-tion. Under direct seeding technology, the conditional net income for the course of the crop rotation made 58.6 thou-sand rubles per ha; fuel consumption -127 kg ha and labor costs -16.98 man-hours per ha which was by 5%, 43% and 11%, respectively, less than those in the control. Sur-face tillage also had an advantage in terms of these indica-tors. Moldboard plowing reduced the intensity of organic matter accumulation 1.5-1.2 times as compared to direct seeding (no-till) and surface tillage. The cultivation of 4 crops in a course of the crop rotation for 3 agricultural years stabilizes economic indicators and soil fertility. The developed technologies for crop optimization in a rotation (the crops in constant demand by the market); adaptive methods of basic tillage; preservation of soil fertility may be used by land users with similar soil and climatic conditions.

The effectiveness of long-term use of various basic tillage systems of dark grey forest soil in the conditions of the Northern Trans-Urals was established. Their impact on the efficiency of barley cultivation depending on the grain (spring wheat) or legume forecrop (vetch for grain) was determined. The research was carried out in a stationary experiment covering moldboard, nonmoldboard, combined, differentiated, stubble-mulch and surface systems of basic soil tillage. The experiments took place during the third–sixth rotations (1996–2018) of two grain-fallow crop rotations spread in time and space. The first crop rotation was: bare fallow – winter rye – spring wheat – spring vetch – spring barley, the second crop rotation: bare fallow – winter rye – spring wheat – spring wheat – spring barley. When cultivating barley following the legume forecrop (spring vetch), it was economically feasible to use basic tillage systems with the elements of minimization. It included non-moldboard and combined tillage with subsurface loosening by a plow with SibIME tines to a depth of 20-22 cm differentiated with stubble-mulch at 12-14 cm and disk harrowing at 10- 12 cm. These methods provided conditions for the formation of productivity close to the moldboard system and practically the same yield of barley, net income and energy efficiency coefficient. Without fertilizers, the yield was 2.97-3.03 t/ha, with the use of N40P40P40 it was 3.47-3.65 t/ha. When planting barley following wheat sown twice, the most effective was moldboard tillage system with a net income of 14.67 thousand rubles/ha without fertilizers and 22.75 thousand rubles/ha with fertilizers and energy coefficient of 2.65 and 2.75. The use of resource-saving tillage methods with repeated wheat led to a decrease in the yield of barley grain by 0.09–0.40 t/ha, and a decrease in the net income of barley cultivation compared to the legume forecrop by 31.0–44.1%.

In recent years, there has been an increasing interest around agricultural science and practice in conservation tillage systems that are compatible with sustainable agriculture. The aim of this study was to assess the qualitative and quantitative changes in weed flora and soil seed bank under reduced tillage and no-till (direct sowing) in comparison with traditional ploughing. In the crop rotation: pea/rape—winter wheat—winter wheat the number and dry weight of weeds increased with the simplification of tillage. The seed bank was the largest under direct sowing and about three times smaller in traditional ploughing. Under direct sowing, most weed seeds were accumulated in the top soil layer 0–5 cm, while in the ploughing system most weed seeds occurred in deeper layers: 5–10 and 10–20 cm. In the reduced and no-till systems, a greater percentage of perennial and invasive species, such as Conyza canadensis L., was observed. The results show that it is possible to maintain weed infestation in the no-till system at a level that does not significantly affect winter wheat yield and does not pose a threat of perennial and invasive weeds when effective herbicide protection is applied.

Постановка задачи. Подаваемый в помещения воздух в жаркое время года должен быть охлажден до комфортных температур. В связи с тем, что дополнительного расхода энергии на это охлаждение не предусмотрено, возможно применить воздухоохладитель испарительного типа. Однако известные в настоящее время результаты экспериментальных и теоретических исследований таких аппаратов не позволяют их проектировать, что препятствует их распространению. Рассмотрено строение такого аппарата и выполнены его теоретические и экспериментальные исследования, результаты которых могут быть использованы для инженерного расчета и конструирования подобных аппаратов. Результаты. Описан сконструированный авторами воздухоохладитель испарительного типа для систем вентиляции. Проведено теоретическое и экспериментальное исследование воздухоохладителя. Получены аналитические соотношения для определения времени движения насадки в «мокрой» камере аппарата, температуры охлажденного воздуха и температуры насадки в любом сечении контура циркуляции. Получены эмпирические соотношения для коэффициента эффективности охладителя и его гидравлического сопротивления. Выводы. Полученные зависимости послужат основой для разработки методики проектного расчета воздухоохладителей косвенно-испарительного типа с перемещающимся псевдоожиженным слоем в поле центробежных сил. Statement of the problem. The air supplied to the premises during the hot season must be cooled to comfortable temperatures. Due to the fact that additional energy consumption for this cooling is not provided, it is possible to use an evaporative-type air cooler. However, the currently known results of experimental and theoretical studies of such devices do not allow for their design, which prevents their spread. The structure of such an apparatus is considered and its theoretical and experimental studies are carried out, the results of which can be used for engineering calculation and design of such apparatus. Results. An evaporative-type air cooler designed by the authors for ventilation systems is described. A theoretical and experimental study of the air cooler has been carried out. Analytical relationships were obtained for determining the time of movement of the material checker in the «wet» chamber of the apparatus, the temperature of the cooled air and the temperature of the checker in any section of the circulation loop. Empirical relationships have been obtained for the efficiency coefficient of the cooler and its hydraulic resistance. Сonclusions. The obtained dependencies will serve as the basis for the development of a methodology for the design calculation of indirect-evaporative air coolers with a moving fluidized bed in the field of centrifugal forces.

Complex Influence

The aim of the research was to study the complex influence of methods and techniques of the main processing of ordinary chernozem, its agrophysical indicators on the yield of oilseed flax. It was found that surface (6-8 cm) and zero tillage did not significantly affect the dynamics of soil moisture in comparison with plowing at 22-24 cm (control). In the spring of productive moisture in the layer of 0-100 cm accumulated 151,5-150-152, mm, respectively. During the growing sea-son of the crop, its number decreased to 60 mm. The density of soil addition on plots without me-chanical treatment before sowing oilseed flax in a layer of 0-10 cm was 1.03 g / cm3, which was 0.01 g/cm3 higher than the variant with surface treatment and 0.04 g/cm3 higher than the control. In the horizon of 20-30 cm, the indicators increased to 1.15 g / cm3 for plowing and 1.23 g/cm3 for zero processing. Before harvesting flax in this horizon, the density of the soil composition cor-responded to the values of 1.27-1.30 g / cm3 and did not significantly exceed the optimal values. Optimal agrophysical values of the soil, as well as the use of fertilizers, pesticides and growth stimulators, provided an average yield of oilseed flax in 2014-2016: 1.75 t/ha at surface and 1.70 t/ha at zero tillage. In relation to the control, this was less by 3% and 6%, respectively. For ener-gy-saving treatments, the conditional net income was 18.3 thousand rubles/ha, and the profitabil-ity was 70%.

Seed peas were sown in 2016-2018 after plowing to a depth of 22-24 cm, as well as with surface (6-8 cm) and zero tillage with the introduction of mineral fertilizers at a dose of N6P26 for the predecessor of mogar (crop sowing). The productive moisture in the 0-100 cm layer before sowing was 167.2 mm when plowing to a depth of 22-24 cm and 158.4 mm-without mechanical tillage. Its content was determined by 18% of the precipitation for November-February and by 2% - the depth of the main tillage. Before harvesting, 64.1 mm of available moisture was preserved on the plowed plots. The density of addition of ordinary chernozem in a layer of 0-30 cm with zero treatment before sowing was 1.15 g / cm3, before harvesting-1.18 g/cm3. This exceeded the con-trol version by 0.07 g/cm3 and 0.03 g/cm3, respectively. The average yield of peas in 2016-2017 was 3.79 t / ha for plowing, 3.71 t / ha for surface treatment (by 6-8 cm), 3.61 t / ha with direct sowing technology, providing a conditional net income 12,9-13,7-14,0 thousand rubles / ha, re-spectively.

Soil compaction can be minimized either mechanically or biologically, using plant species with vigorous root systems. An experiment was carried out with soybean (Glycine max) in rotation with triticale (X Triticosecale) and sunflower (Helianthus annuus) in fall-winter associated with pearl millet (Pennisetum glaucum), grain sorghum (Sorghum bicolor) or sunn hemp (Crotalaria juncea) in spring. Crop rotation under no-till was compared with mechanical chiseling. The experiment was carried out in Botucatu, São Paulo State, Brazil. Soil quality was estimated using the S index and soil water retention curves (in the layers of 0-0.05, 0.075-0.125, 0.15-0.20, 0.275-0.325, and 0.475-0.525 m deep). Crop rotation and chiseling improved soil quality, increasing the S index to over 0.035 to a depth of 20 cm in the soil profile. The improved soil quality, as shown by the S index, makes the use of mechanical chiseling unnecessary, since after 3 years the soil physical quality under no-tilled crop rotation and chiseling was similar.

Horseweed is an increasingly common and problematic weed in no-till soybean production in the eastern cornbelt due to the frequent occurrence of biotypes resistant to glyphosate. The objective of this study was to determine the influence of crop rotation, winter wheat cover crops (WWCC), residual non-glyphosate herbicides, and preplant application timing on the population dynamics of glyphosate-resistant (GR) horseweed and crop yield. A field study was conducted from 2003 to 2007 in a no-till field located at a site that contained a moderate infestation of GR horseweed (approximately 1 plant m−2). The experiment was a split-plot design with crop rotation (soybean–corn or soybean–soybean) as main plots and management systems as subplots. Management systems were evaluated by quantifying in-field horseweed plant density, seedbank density, and crop yield. Horseweed densities were collected at the time of postemergence applications, 1 mo after postemergence (MAP) applications, and at the time of crop harvest or 4 MAP. Viable seedbank densities were also evaluated from soil samples collected in the fall following seed rain. Soybean–corn crop rotation reduced in-field and seedbank horseweed densities vs. continuous soybean in the third and fourth yr of this experiment. Preplant herbicides applied in the spring were more effective at reducing horseweed plant densities than when applied in the previous fall. Spring-applied, residual herbicide systems were the most effective at reducing season-long in-field horseweed densities and protecting crop yields since the growth habit of horseweed in this region is primarily as a summer annual. Management systems also influenced the GR and glyphosate-susceptible (GS) biotype population structure after 4 yr of management. The most dramatic shift was from the initial GR : GS ratio of 3 : 1 to a ratio of 1 : 6 after 4 yr of residual preplant herbicide use followed by non-glyphosate postemergence herbicides.
