Authors: Yu Ismailov L , Safin R R , Safina A V 
Published: April 2022

Abstract
In this work, experimental studies of water extraction of the barren part of sea buckthorn, namely bark, wood, leaves and shoots, have been carried out. Analyzed the yield of water-soluble substances relative to the feedstock, depending on the temperature and duration of the process. It was found that to obtain the maximum possible amount of water-soluble substances during the extraction of leaves, bark and woody parts of sea buckthorn, a temperature of 40°C is sufficient. To extract the maximum possible amount of biologically useful substances from sea buckthorn shoots, a higher temperature and a longer extraction time are required. The diffusion coefficients were calculated for different parts of the sea buckthorn on the basis of the body shape coefficient and the value of the rate of the regular mode of the extraction process. The greatest value of the diffusion coefficient is observed in the sea buckthorn bark, which is characterized by high porosity. The diffusion coefficient in the leaves has the lowest value, which is explained by the closure of the pores due to the fine size of the raw material and its rapid drying during transportation and storage.

Published: April 2022

Abstract
Small forms of management of the Republic of Angola are in great need of support and development, since according to the World Bank, 80% of Angola’s agricultural production, which involves 46% of the population, are small subsidiary farms with an area of 2 hectares without mechanization, infrastructure, high-quality seed and other means of production. The mass introduction of motorcycle cultivators with a capacity of 3-5 to 12 hp with a set of machines and tools for them will significantly accelerate the transition from manual labor to mechanized. It is obvious that the modernization and optimization of these tools is a continuous process, where each user, to one degree or another, individually adjusts the tools acquired from the factory manufacturer to their soil conditions, seed material and power of the tractor. One of the components of the agricultural production process is sowing. In this paper, a precision seeding drill of a motor-block format and its working bodies a coulter group fo r s oil conditions of the Republic of Angola, are considered. A review of the theoretical prerequisites for substantiating the design parameters of a tillerblock seed drill for sowin g sorghum seeds was carried out, and the optimal parameters of the coulter operation process were determined depending on the speed of the unit (V km/h), the angle of attack of the coulter stand (α, deg), the angle of soil crumbling (β, deg). Scientific research was carried out according to the strategy of modernization of agriculture in Angola.

Authors: Kuklina A G , Ozerova N A 
Published: April 2022

Abstract
The facts of the appearance and distribution of invasive species Impatiens glandulifera Royle and I. parviflora DC were studied. (Balsaminaceae) in the Moscow region (Central Russia). Field route methods, analysis of herbarium collections (MHA, MW) for the period 1880-2021 and numerous observations of invasive Impatiens L. species available in Open Access (online) were used. Maps were compiled showing the formation of modern invasive populations of Impatiens in the study region. The historical features of the dynamics of the development of the invasive process in each species are noted. It was revealed that the first finds of I. parviflora in the Moscow region were made several decades earlier than I. glandulifera. In the invasive process, I. parviflora has a lag-phase period lasting more than 70 years; in I. glandulifera, this period is about 50 years. The exponential phase falls on 1960-1970, when the rate of appearance of invasive populations increases significantly and active naturalization of both species begins. It should be noted that I. parviflora prevails over I. glandulifera in terms of the rate of development of biocenoses in the region, which is characterized by a narrower ecological optimum. Currently, I. parviflora covers the entire territory of the Moscow region, with the exception of one remote area. Invasive populations of this species are concentrated in coniferous-broad-leaved and small-leaved forests, on wastelands and glades, including areas with dry soil. The invasive range of I. glandulifera in 2021 is almost as extensive, but unlike the previous species, it is characterized by ecological specificity, since the species prefers humid habitats, grows along the banks of reservoirs, rivers and streams, and along damp ditches.

Abstract
The problem of solid waste management is acute for modern society. The article studied the existing landfill for municipal solid waste in the city of Uralsk. The city is growing every year, and the amount of solid household waste is increasing accordingly. Municipal solid waste is usually generated from various sources associated with various human activities. As a rule, in the main, they come from households, markets or commercial organizations. Another of the problems of household waste is the heterogeneity of garbage in nature, which creates a certain difficulty in sorting and using it as a material. Local authorities are trying to solve the problem with a number of measures. For this, a waste sorting shop has been launched on the territory of the landfill, which unloads the landfill a little. It is also planned to create a new landfill, but this is only under consideration. Therefore, the problem of disposal of municipal solid waste remains relevant today. Thus, in our studies, alternative solutions for the disposal of municipal solid waste using recycling were proposed.

Abstract
The polluted wastewater treatment is one of the main issues in agro-industrial complex. This article is devoted to the primary water purification research for its further treatment with ferrate technology. The technology implies the wastewater treatment from household and industrial waste resulting from agricultural enterprises. The ferrate technology provides a high efficiency of pretreated water purification, in comparison with other existing methods. The article substantiates such an advantage accordingly. The waste generated as a result of wastewater treatment is non-toxic and disposal. The article proposes a new method of preliminary water purification based on its treatment between a galvanic couple in the presence of the calcium hydroxide. This method can be used at water treatment plants and at enterprises carrying out industrial activities in agriculture. The method is applicable only after mechanical filtration at the stage of primary water treatment. The proposed method provides water treatment from a wide range of various origins contaminants. The article also describes an experimental equipment specially designed for the proposed method’s implementation and further research. The equipment provides continuous water treatment consuming electricity, quicklime and compressed air. To maintain the lime particles in suspension condition the airflow is supplied through an aerator. The article applies the turbidimetric analysis method to conduct an in-depth analysis of the water treatment processes and determine the relative reagent concentration in the working area. The article also proves the absence of interface formation between water and milk of lime when subjected to air flow.

Published: April 2022

Abstract
Agricultural lands occupy 90% of the Southern Urals. The influence of agricultural activity on the catchment area and changes in it on the runoff of melt water from the catchment areas of its steppe zone in 1936-2020 years is considered. on the example of the unregulated upper reaches of the Samara River. In the pre-war 1936-1941 years in the grass-field system of agriculture, with an increased density of soils under perennial grasses, half of the melt water entered the rivers. During the war years, with the deterioration of the culture of agriculture, the runoff coefficient increased to 0.7. After the war, with an increase in the area of arable land and the transition to autumn plowing, the retention of melt water in the fields increased with a corresponding decrease in the runoff coefficient to 0.35. Slightly changing farming system 1966-1990 years the runoff coefficient has been stabilized at an average of 0.29. Frequent land-use changes 1990-2020 years led to an unstable flow regime of melt water. The total runoff of melt water from the catchment area is determined by the ratio of its lands with different filtration coefficients of frozen soils. A method is proposed for determining in the laboratory the rate of absorption into frozen monoliths, depending on the temperature and moisture content of the soil, and its definitions are presented for the main lands of the steppe zone.

Abstract
Varietal agricultural technology developed for new varieties is a must for successful promotion of the variety on the market. It should be implemented after successful tests in various soil and climatic conditions. Studies on the study of morphophysiological features of the response of a new variety of spring triticale Timiryazevskaya 42 to nitrogen fertilizers were carried out in two contrasting meteorological conditions of the year. In a dry year, in which the HTC for the growing season was 0.9, it was obtained from 3.17 t/ha of grain in the variant without fertilizers to 3.93 t/ha in the variant with the application of 150 kg/ha of a.i. nitrogen. In a more favorable year, in which the HTC was 2.0, from 30 to 50% more grain was obtained in different variants of the experiment than in the dry one. The yield ranged from 5.49 t/ha (control) to 8.05 t/ha in the variant with the application of 150 kg/ha of a.i. nitrogen. Productivity is made up of productivity elements that, under favorable conditions and good agricultural technology, develop better. In this case, the economic yield tends to the potential value. For spring cereals, the structure that ensures productivity consists of high productive bushiness - 2.0-2.5 pcs/plant, a large number of spikelets per spike and full-fledged grains per spike (3-5 grains), grain weight per ear exceeding 1.8-2 g.

Abstract
The degradation of oak forests is an acute problem throughout the territory of the Russian Federation. Pedunculate oak is a valuable and durable tree species. The stability of oak forests is largely determined by biotypic characteristics. However, in recent years, anthropogenic impact is the main reason for the drying out of oak forests, which leads to the death of resistant pedunculate oak climatypes. The article presents the results of a study of pure stands of low-stemmed pedunculate oak on the territory of the Orenburg region. The silvicultural characteristics of plantings are given, their phytocenotic structure is described. It was found that in dry oak forests and oak undergrowth the stand was characterized by a low growth class, in fresh oak forests the highest growth class was noted. The plant density varied significantly from 0.3 to 0.7. In dry oak forests, the density index tended to decrease with age. The maximum plant density was observed at the junction of ripe and overmature ages, at the age of 60 years. The state of pure pedunculate oak stands on the territory of the Orenburg region can be assessed at the moment as satisfactory, but requires significant measures to promote seed reforestation.
