Based on the results of observations, it was specified that when decreasing soil moisture there is a disproportionate decrease in the average daily evapotranspiration (ET). Thus, in the range of soil moisture of 94-80% minimum moisture-holding capacity (MMHC) ET was 9,76 mm a day, and in the range of 70-62% MMHC - its value decreased by 3 times. When the soil moisture reached 58,5% MMHC, the value of ET did not exceed 0,5 mm a day, which is 20 times less than the initial one. It was determined that the decrease in soil moisture by 10% in the range of 90 - 70% MMHC occurs during 3 days, and from 70 to 60% MMHC and from 60 to 58% MMHC - during 8 days. When soil moisture is 70% MMHC and below, the actual evapotranspiration is less than ETo that proves the effect of water stress on soybeans ET. When calculating water stress coefficient (Ks), a mathematical model based on the dependence of Ks on soil moisture as a percentage of MMHC was obtained. The average absolute percentage error (MAPE) is 8,6%, which corresponds to the high accuracy of the obtained dependence. In the range of soil moisture from 58 to 80% MMHC, the water stress coefficient is calculated by the formula Ks =-0.0011·FC²+0.1925·FC-7,4541. When having soil moisture as 80% MMHC and above, Ks = 1. A comprehensive comparative assessment of existing methods for calculating waster stress coefficient Ks was taken and it was found out that the actual values of Ks when having soil moisture as 80-70 and 60-65% MMHC by 8-14 % and 72-32 %, respectively, less than Ks FAO 56, and by 35-40 % larger than those determined by Saxton method. It was proved the need of taking into account the reduction in evapotranspiration when calculating water balance under water stress of plants. The calculation of evapotranspiration (ETs) by the Penman-Monteith method, without taking into account the water stress coefficient, showed that the value of the actual and calculated water balance coincides only when soil moisture does not exceed 62% MMHC. With a further decrease in soil moisture, the estimated soil moisture was 20% less than the actual, which led to the errors in determining soil moisture after irrigation, because its actual value was almost 100% MMHC, and the estimated one was only 60% MMHC. It was proved that the determination of water balance by calculation methods without taking into account the water stress coefficient leads to significant errors.

According to the results of previous studies it was specified that the soils of the research areas in south of Ukraine are not provided with the optimal content of nutrients for normal growth and development of fruit crops. As a result of that, a long-term field experiment was set up, which aimed at increasing soil fertility, yield and fruit quality of intensive plantations of peach and apple trees under drip irrigation as well as at improving soil management principles. The field experiment was set up in 2009 on the perennial plantations in Kherson and Mykolaiv regions on the soils with different properties using the water of different quality when applying traditional cultivation technology in the south of Ukraine. It was observed the positive effect on the yield of perennial plants when applying the following fertilizer systems: organic-mineral ("Rost-concentrate"), mineral (N120P30-90K75-120), and organic ("Gumoplant") when irrigating with water of different quality. Thereat, the soil moisture in the layer of 0-60 cm was in the range of 75–90% of MMHC depending on the soil grading. The highest increase in peach yield (33%), in comparison with the check plot was observed on sod sandy soils in SE "DAF named after Solodukhin" in Kherson region when applying mineral fertilizers. The higher dry matter content in fruits by 2,6% and nitrate content by 29% were also observed when using mineral fertilizers on this farm. The highest yield increase up to 21,16 t/ha on dark chestnut medium loam soils in private joint stock company "Radsad" in Mykolayiv region in apple orchards was obtained when using organic-mineral fertilizers and irrigating with partially suitable water. The yield increase up to 26,81 t/ha was obtained on chornozem southern heavy loam soil in private joint stock company "Kamyanskyi" in Kherson region when irrigating with water suitable for irrigation and up to 32,62 t/ha of yield increase was obtained on dark chestnut medium loam soil in "Bilozerskyi" state farm in Kherson region when irrigating with water suitable for irrigation. Higher dry matter contents were recorded under mineral fertilizers, higher sugar content - under organic-mineral and mineral fertilizers, nitrate content under organic fertilizers. The content of nitrates under different fertilization systems for all fruit trees did not exceed the maximum concentration limit of 60 mg/kg. It was also found out that the highest effect on the yield of perennial plantations had organic-mineral fertilizers with a correlation coefficient of 0,75.The results of mathematical data processing showed that the fertilizers applied along with drip irrigation (fertigation) had a positive effect on the yield of peach and apple trees and the quality of their fruits.

The article presents the results of the research, which are the basis of making a hydrodynamic model of the formation of drainage runoff of closed horizontal drainage on drainless and slightly drained irrigated lands in the dry steppe zone of Ukraine. The relevance of the research is in their need when designing the systems of horizontal drainage, determining drain spacing, modes of operation and the evaluation of drainage efficiency during its operation when irrigating with the use of modern sprinklers from a closed farm network. The objective of the research is to develop a generalized hydrodynamic model of formation of closed horizontal drainage runoff when irrigating from a closed farm network on drainless and slightly drained lands, which are typical for the watershed plains and coastal lowlands of the dry steppe zone of Ukraine. The task of the research to determine the basic conditions and factors of formation of horizontal drainage runoff, to specify the structure of groundwater inflow to the drains when having optimal drain spacing in the closed farm network and to define the prospects and areas of further research. Research methods and techniques: long-term (1975-2020) field experiments on drained areas with different drain spacing in typical hydrogeological conditions for watersheds and coastal lowlands; water balance studies; theoretical research methods (analysis and synthesis, comparison, generalization, zoning); to determine the structure of groundwater inflow to the drains, the method of electrohydrodynamic analogies when using the laboratory integrator EGDA 9/60 was applied. As a result of the research it was determined that in the conditions of a closed water farm network it is possible to increase drain spacing from 120-220 m to 240-400 m. When studying all the conditions of drainless and slightly drained watershed plains and coastal lowlands, the main sources forming the regime of groundwater and drainage runoff are the precipitation of 420 mm or 55.0% of water input, irrigation water - 340 mm or 45.0%, including 266 mm or 35,0% from irrigation and 75 mm or 10,0% from filtration from the canals. The analysis of the hydrodynamic model of drainage runoff formation shows that when having drain spacing as 240-400 m, the inflow from the zone located above the bottom of the drain is 2.6-4.8% of the total inflow to the drain. The ascending flow under the bottom of the drain enters it at an average angle of 600 and in all variants of drain spacing is 95.2-97.2% of the total inflow. When drain spacing increases from 240 to 300-400 m, the horizontal inflow from the area located below the bottom of the drain decreases with a corresponding increase in the ascending flow under the bottom of the drain. The average width of the ascending flow to the drain at the edge of the active zone of groundwater (9.0-10.0 m below the drain) is 13.0-20.0 m.

Topicality. In the conditions of modern management the issue of territory protection against the harmful effects of water acquires special urgency. In the southern region of Ukraine alone, more than 2.9 million hectares of land and 2,135 settlements are affected by flooding and underflooding. An illustrative example of the complexity of solving the problem of protection of drainless territory against the harmful effects of water is the village of Nova Mayachka of Oleshkv district in Kherson region, which is located within a large depression morphostructure and is affected by the Kakhovske reservoir, North Crimean Canal, irrigation systems and climate fluctuations. Purpose of the work is to substantiate a set of measures to protect the territory of Nova Mayachka village of Oleshky district in Kherson region against the harmful effects of water. The main task of the research is to specify the factors of flooding and underflooding developing in the village, to determine the mechanism of GWL regime and to develop a set of protective measures. Methods and the objects of the research. The research was carried out at the research and production site, which is located within the village. As part of the research, an analysis of natural and water management conditions, assessment of the hydrogeological and reclamation condition of the territory as well as the efficiency of drainage systems operation were performed. Research results and main conclusions. Based on the research results, the reasons of flooding, patterns of GWL depths and fluctuation dynamics and the efficiency of different types of drainage in the village of Nova Mayachka were specified. It was found out that in the conditions of stable operation of wells vertical drainage ensured the weighted average depth of groundwater level in the village of 2.9-3.1 m against 1.6 m before the start of drainage operation or in conditions of its insufficient functioning. But over time, the existing protection system of the village failed to provide the necessary groundwater lowering due to the deficiency of its work and the increase in water load on the territory due to increasing rainfall and enlarging irrigation areas. Groundwater levels rose to 0-2 m, and in wet periods against the background of drainage the flooding of drainless territory was observed. Recently, groundwater levels in the village have tended to a rise above critical depths. The drainage facilities by its design features fail to eliminate surface water flooding. To protect the village of Nova Mayachka from flooding and underflooding, a set of measures is proposed, which provides for the installation of a combined drainage system with free-flowing water removal or pumping of drainage runoff outside the village into the North Crimean Canal or the Dnieper River.

The article provides a comprehensive analysis of the current state, reasonably promising directions for the development of microirrigation methods in Ukraine through the prism of climatic transformations. The dynamics of the areas of agricultural crops irrigated using microirrigation methods in the world and in Ukraine, as well as the structure of the areas of micro-irrigation in the context of regions of Ukraine and types of crops are shown. The largest agricultural enterprises, which are domestic leaders in the introduction of microirrigation methods, equipment manufacturers and suppliers of technical means of microirrigation, have been identified. The current stage of development of microirrigation in Ukraine is defined as a level of high understanding of technologies of its application and constantly growing use of opportunities and expansion of spheres of application of these methods of irrigation. The essential importance of domestic research institutions in the development and popularization of microirrigation methods is emphasized. With the use of theoretical methods of scientific research (analysis and synthesis, comparison, classification and generalization), the most significant scientific results of IWPaLM NAAS are systematized and a list of prepared regulatory and methodological documents in the direction of microirrigation is given. The need of Ukraine in microirrigation systems for agricultural crops for the period up to 2030 is given, trends and promising directions for the development of microirrigation methods that correspond to both the global trend of environmentally friendly irrigation and the principles of resource and energy conservation are given.

The most effective use of highly-productive crop species in fodder production and obtaining of sustainable yields of agricultural products is only possible when following scientifically sound technological processes of land reclamation in combination with a set of agronomic measures for their cultivation. The aim of the research is to develop the main technological parameters of growing highly productive fodder crops (Japanese millet, amaranth and fodder beans) on the drained lands in the humid zone of Ukraine. The results of research on determining the main technological parameters of growing highly-productive fodder crops (Japanese millet, amaranth and fodder beans) on drained lands are highlighted. It was specified that when cultivating these crops it is necessary to adhere to the optimal sowing dates taking into account the purpose of their use (green mass, grain). When they are sown too early there is a decrease in field seed germination and increase of germination period, thinning of crop plantings, intensive spread of weeds and also the probability of crops damage by spring frosts increases. When they are sown too late, especially in case of small-seeded crops (amaranth), drying of the top layer of soil is possible, which is unacceptable in the period of germination and emergence of seedlings. The most favorable conditions for the formation of herbage when cultivating on drained peat soils are formed when the crops are sown on May 15 (by 8.1–16.7% more of herbage and by 2.1–9.6% of dry matter is formed). The main technological parameters of cultivating Japanese millet, amaranth and fodder beans are determined, incl. by phases of development and taking into account the critical periods of their optimal moisture supply, agronomic measures and optimal fertilizer rates. The admissible terms in which the reclamation system should provide drainage of excess waters and the recommended levels of ground waters and the humidity rates in a soil root layer in the vegetative period at the crop cultivation were determined. It was specified that during the growing season the needs of Japanese millet, amaranth and fodder beans in moisture in the soil root layer change depending on their biological needs and current meteorological conditions. Soil moisture rates were specified as following: on peat soils the optimal one is 65–75%, the lowest permissible one in the summer period is 55–60%; on mineral soils, respectively - 65-80% and 55-60% of FMHC. It was established that modern climate change in the Western Polissya of Ukraine (uneven distribution of precipitation during the growing season, abnormal average daily air temperature fluctuations and low night air temperatures (˂10oС in summer months) have a negative impact on the cultivation of heat-loving crops (Japanese millet). In the context of climate change, it is necessary to provide for the accumulation of sufficient water volumes in storage tanks or reservoirs to supply them for irrigation of

In terms of water consumption from decentralized water supply systems there are a number of problematic aspects that negatively affect water quality, especially drinking water supply, namely: lack of modern control methods and integrated water treatment systems, qualified service personnel, long logistics of components and reagents, long distances to the final water consumer, inability to respond timely to the need of control laboratory equipment calibration and the failure of units and others. Unpredictable natural or man-made factors further complicate these problematic aspects. All this and the constant changes in the requirements to water quality and technological processes, leads to the search of new, modern approaches to solving such problems and issues of uncentralized drinking water supply. Therefore, this paper analyzes the current experience of developing small autonomous water purification systems for drinking water supply, which do not require constant presence of the operator and laboratory quality control of water and can work automatically in difficult conditions. Also a rationale for technological and structural design as well as the description of adaptive water purification systems using an adaptive approach to the structure as a whole, individual units, assemblies and to the power supply of electrolytic processes, giving it adaptive properties for the use in modern drinking water treatment is provided in the paper. The adaptive function of neutralizing the manifestation of dangerous biological agents and the efficiency of the system is designed for man-made and natural emergencies and water disinfection from bacteria and viruses. The pH was chosen as the main control parameter of water quality. The system uses an effective process of synthesis by electrolytic methods of coagulant, disinfectant and destructive effects on hazardous biological agents - pulsed current with changing parameters and shape. In case a working solution changes the pH, the parameters of the pulsed load current are changed by the adaptive power supply to the most efficient one. The proposed approach and model of the system are effective and preventive and is offered as an option to improve existing water treatment systems for drinking water supply.

The article analyzes the ways to improve the water supply system at agro-industrial enterprises. It is stated that the Institute of Water Problems and Land Reclamation of NAAS proposed to improve closed water supply systems at these enterprises to spend water and energy rationally and economically by developing highly efficient wastewater treatment technology to reuse wastewater and its sediments for technological needs. During the work, the main tasks to be solved were the analysis of the reasons of unsatisfactory operation of traditional wastewater treatment plants and their current quality indicators and improvement of the rational technological scheme of closed water supply at the agro-industrial enterprises. Scientific and practical results were obtained by analyzing the operation of wastewater treatment plants of industrial enterprises dealing with agricultural products processing, their quality indicators and known methods of improving technological schemes of biological wastewater treatment. It was specified that traditional technology of biological wastewater treatment do not ensure the proper treatment quality, as the quality of wastewater from enterprises has significantly deteriorated due to the inflow of harmful impurities (xenobiotics, heavy metal ions, etc.) and high concentrations of organic matter, the content of which amount to: suspended solids> 1000 mg/dm3, COC> 10000 mgO2/dm3, BOC5> 6000 mgO2/dm3, BOCcomplete> 2000 mgO2/dm3, nitrogen and phosphorus ≤50 mg/dm3, which prevents the effective operation of aeration tanks. The practicability of improving the "bioconveyor" technology by downward filtration through fibrous loading in bioreactors and upward filtration through floating filter loading in contact and clarifying filters to increase the efficiency of wastewater treatment was scientifically substantiated. It was proved that this method provides high efficiency of biological wastewater treatment by reducing the amount of sediment and the absence of reverse activated sludge, and thus reducing capital and operating costs. Natural mechanisms of household sewage treatment with reuse of water and sediments when cultivating agricultural crops are used as much as possible are used in the specified system of water supply at agro-industrial enterprises. The optimal design and technological parameters of these structures are determined using the recommendations developed on the basis of our experimental research. The proposed technology of closed water supply at agro-industrial enterprises provides for the separation of water supplied to consumers into technical and drinking one, as well as supplements of sewage treatment plants with bioreactors and contact-clarifying filters. Such systems ensure a minimum intake of water from natural water sources having its preliminary treatment directly in water reservoir, maximum use of treated wastewater and protection of the environment against wastewater pollution.

Relevance of the research. A scientific and theoretical analysis of the legislation in the field of monitoring of land use and protection was carried out. The problem of information imperfection on the quantitative and qualitative state of land resources, which is the basis of land monitoring, was identified. The problem of land monitoring is the imperfection of the monitoring system itself, namely the collection of information on the land state, the spread of degradation processes by various entities of monitoring. The current Regulations on land monitoring were considered and it is proposed to provide for the expansion of the types of analytical work, to adapt the European standards in the selection, transportation and storage of soil samples, to impose mandatory quality control on all works. According to the current legislation of Ukraine, the main task of monitoring is to monitor the dynamics of the processes taking place in the field of land management. Monitoring data are used in making decisions on construction, establishing permitted types of land use, which help prevent land degradation. The updated monitoring data enable public administration bodies to make appropriate demands to land users to eliminate the violations in the field of land use and protection, as well as to bring to justice those responsible for these violations. To ensure the effective functioning of the unified monitoring system, it is necessary to solve a number of organizational, technical and other problems. The main disadvantages of this system are the obsolescence of technical, methodological and information equipment of the monitoring system centers used during observations; lack of a single observation network; inconsistency of separate information technologies used by different entities of monitoring; inconsistency of normative-technical and normative-legal provision with modern requirements. These problems can be solved by creating a new network of observations, but it requires a large amount of funding. The Concepts of the State Target Program for the development of land relations in Ukraine and the Concepts of the State Program for Environmental Monitoring were considered, which provide for the improvement of the land monitoring by maximizing the existing potential and gradual improvement of organizational, legal, methodological and technical support of the monitoring system, taking into account current information needs and the recommendations of the UN Economic Commission for Europe. A necessary requirement for the effective counteraction to violations of land legislation and non-compliance with the norms of rational land use is the improvement of the regulatory framework for land monitoring.
