Opis:: Fertilizers have a significant influence on the forming of the circulation of substances and energy in soils, agroecological state of lands, as well as the quality of agricultural products. Fertilizers and ameliorants, as some of the most effective means of restoring soil fertility, have a considerable influence on the agroecological condition and agrochemical indicators of arable soils in the process of their agricultural usage. The article researched such ecological aspects of using mineral fertilizers as changing the chlorine content in soil solution, potassium, calcium and magnesium content in soil intake complex as well as gross sodium content in soil after continuous usage of fertilizers in field crop rotation. The experimental part of the work was done in continuous stationary experiment in the field rotation of grain and beet crops with a set of crops traditional for the region defined in 1964. It was defined that the chlorine of fertilizers does not produce stable compounds in soil and migrates a lot in its profile. Using fertilizers in field crop rotation in a dose of 45–135 kg of K2O/ha does not contribute to chlorine increase in physiologically active 1.5 m deep soil layer. At continuous fertilizer usage, there have been essential changes in the ashed fertile soil in the composition of its intake complex – the number of calcium and magnesium exchangeables has decreased, which entails worsening of the physical and chemical qualities and as a result leads to decreasing fertility level. The research results have evinced that the ratio between magnesium and potassium in a soil intake complex drops to 2.6–3.6 as a result of continuous potassium with fertilizer usage, according to the checking data without fertilizer application it makes up – 4.2, which corresponds to optimal ratio of Mg : K = 2–5.

Opis:: Forests perform essential ecological functions - water protection, sanitation, health, recreation, and aesthetics. The research aimed to substantiate the ecological and economic importance of forest resources in the Kyiv region and analyse their rational use and protection. The article shows that the Kyiv region belongs to the regions with an average level of forest cover – 592.8 thousand hectares or 22.2%. The level of forest cover is uneven in the area of the Kyiv Forest zone. It is 44%, and in the area of the Forest-Steppe, it is much lower and decreases from north to south. The use of forest resources in the Kyiv region in 2019 amounted to harvesting liquid wood of 999.5 thousand m2, and deforestation was carried out on 75.5 thousand hectares. The region’s volume of forestry works and services amounted to 8,9 million dollars, and the wood stock makes 90805,9 thousand m2. Emphasis is placed on the importance of protecting the Red Book species of plants and fungi that grow in the forests of the Kyiv region. Examples of harmful economic activity in the areas belonging to the nature reserve fund and large-scale fires in April 2020, which covered more than 3.5 thousand hectares of forests in the region and caused damage to forest fauna and flora. The studied region’s positive environmental and economic factors have been admitted by planting trees on an area of 2151 hectares and sowing seeds of forest species on an area of 67 hectares in 2020.

Opis:: At present, the problem of the availability of high-quality fresh water is urgent. The reservoirs from which water is extracted are running low. The amount of fresh water on the planet has decreased significantly in recent years. A big problem for the use of fresh water is its pollution. Groundwater remained relatively clean, but even when used, it needs to be controlled. Goal of research was the quality control of water from ponds and water sources in the National Dendrological Park (NDP) "Sofiyivka" of the National Academy of Sciences (NAS) of Ukraine in terms of physicochemical and bacteriological indicators and a study of the park's hydrosystem. When conducting research, potentiometric, gravimetric, titrimetric, colorimetric and spectrophotometric methods were used. The hydrosystem of the NDP "Sofiyivka" of the NAS of Ukraine, created during the period of its foundation, has basically retained its planning forms and all its artificial structures. The water system is an important environmental factor that contributes to the quality development of plants, and also has an aesthetic value. The analysis of the results of a study of the physicochemical and bacteriological composition of drinking water from the studied water catchments showed that the water is safe for consumption in terms of such indicators as the content of sulfates, nitrites, chlorides, but contains a significant amount of nitrates and has a high hardness, which can contribute to the development of a number of diseases. Long-term consumption of such water will have a negative impact on the human body. In all water samples from the capture, the growth of common coliforms in 100 cm3 and the presence of Escherichia coli were found, which is dangerous when drinking unboiled water and can bring to intestinal infectious diseases. According to the obtained experimental results of the quality of the studied water samples from the Krasnostavsky, Upper and Lower ponds of the NDP "Sofiyivka" NAS of Ukraine, the general physical and chemical indicators fully comply with the established standards, but the results of studies of the ponds in terms of bacteriological indicators, namely the index of lactose-positive E. coli indicate their significant excess and non-compliance with the standards in the Krasnostavsky and Verkhny ponds by 48 and 12 times, respectively.

Opis:: The purpose of the researches was to determine how the potassium balance depended on fertilizing system and how it influenced crop productivity. The experimental part of the work was carried out under the conditions of continuous (since 1964) stationary experiment of the Chair of Agrochemistry and Soil Science the basis of which is a 10-field crop rotation deployed in time and space. The soil of the experimental plots is ashed heavy loamy black soil on loess. For simplifying balance calculations, the number of comparable and equal articles in the coming part and in the extracted one was reduced. It was considered that the total potassium amount which came from the atmosphere and with seeds was responsible for erosion losses and those from washing off. The results obtained show that potassium balance and its intensity in every rotation was formed unevenly and depended considerably on the level of its coming together with fertilizers and removing when harvesting. It has been proved that when increasing the used fertilizer dose, the balance volume rises which characterizes potassium circulation size in agrocenosis. The potassium balance data analysis when leaving unmarketable part in the field has displayed that its intensity increases significantly. Leaving the unmarketable part of the harvest in the field balances potassium in the soil significantly without using high mineral fertilizer doses which entails a number of ecological problems. It has been defined that the majority of crop productivity can be observed at a potassium balance of -30 kg (kg per year). Only clover productivity at a more negative potassium balance has decreased which testifies to its wider tolerance zone as to the given nutrient content in the soil compared to other crop rotations.
