“…The volume of pollutant emissions from natural dumps is about 70 thousand tons per year. 10 tons of carbon oxides, 1.5 tons of sulfur dioxide and a significant amount of gaseous substances are released from the waste heap per day, since all dumps contain FeS 2 [Lisiecki et al, 2007;Sonko et al, 2018].…”

Open pit coal mining is a global problem, because mines occupy large areas that completely change the relief, dramatically affect ecosystems, as a result of which they lose most of their functions, and a significant part of the fertile soil degrades and becomes unsuitable for agricultural activities. In the presented work, the initial stage of soil formation was studied, the parameters of the granulometric composition of uneven-aged rocks of Donbas mine dumps, their nutritional regime, and the species composition of soil algae were studied. Samples were taken from three different-aged rock dumps of the mines: ˮSouth-Donbaska -3ˮ (rock storage for 40 years); ˮSouth-Donbaska -1ˮ (storage of rock for 52 years), ˮTrudovska №5 -bis (storage of rock for more than 100 years). The agrochemical parameters of the rock were determined in the samples: pH water , humus, nitrate nitrogen, mobile phosphorus, exchangeable potassium, particle size distribution. The determination of granulometric fractions of 0-20 cm layer of rock dumps of the mines shows, along with the age, a potential increase of the dump of fine fractions and a decrease in the fraction of stones from 83% in the dump of the South-Donbaska mine, and by 30 to 64.7% in the dump of the Trudovska No. 5-bis. The proportion of the clay fraction is not high in all dumps and it does not exceed 1%, but its appearance indicates the initial stage of a soil structure formation. Soil formation begins with the colonization of mineral rocks with soil algae. The species composition of soil algae, the quantitative accounting were determined by microscopy of a freshly selected soil sample and by cultural methods. Algae species were determined by determinants. In the rock dump, the structure of algal groups becomes more similar to, their structure in the background soils of the territory. The dominance of the representatives of Chlorophyta and Cyanophyta in the rock indicates the steppe process of soil formation. The data obtained contribute to the expansion of the ecological and biological understanding of the initial stages of the formation of soil cenoses.

“…One of the results of human activity is soil contamination with heavy metals (HM) [6,7]. It has been determined that excessive amount of HM in the soil worsens physical, physical-chemical, microbiological and agrochemical properties, increasing the content of HM in plant production [8,9,10].…”

Conservation agriculture is becoming a priority for Ukraine as well as for many countries of the world. It is a known fact that high content of heavy metals in the soil impairs fertility and carries the risk of crops translocation. An agroecological effect of obtaining and applying organic-mineral fertilizers has been insufficiently studied so far. The purpose of the work is to determine possibilities to produce new organic-mineral fertilizers based on sewage sludge with enhanced adsorbing properties, to establish their agroecological efficiency. Methods. Field, laboratory-analytical, statistical-mathematical. Results. From the agroecological point of view, the production process of organic-mineral fertilizers based on the sewage sludge of Kharkiv is justified. It allows us to expand functional capabilities of reagents, enhancing adsorbing properties of heavy metals. It is proved the advantage of organic-mineral fertilizers over the traditional ones on chernozem typical. After fertilization, the content of total carbon in the soil increased, the content of humic acids increased by 1,5 – 2,8 times, fulvic acids – by 1,1 – 1,7 times, the total sum of humic substances – by 1,3 – 2,1 times compared with no fertilizer option. It is established that application of organic-mineral fertilizers promotes blocking of heavy metals in soil and prevents translocation to plant. Maximum yields of corn were obtained after the local application of granular organic-mineral fertilizers – the yield increase was 41% compared to the control, after introduction of bulk fertilizers – 32% compared to the control. Profit was $ 23 -36 per hectare. Conclusions. The process of organic-mineral fertilizers production on the basis of sewage sludge in Kharkiv is substantiated from the agro-ecological point of view. Agroecological and agrochemical efficacy of sewage sludge use as compared to organic and mineral fertilizers applied in equivalent doses separately was established on the typical heavy loam chernozem. After introduction of organic-mineral fertilizers based on sewage sludge a significant increase in the concentration of trace elements and heavy metals was found in the black soil but these indicators did not exceed the established maximum permissible concentrations. The implementation of the proposed technology will reduce bioavailability of heavy metals and their mobility in the soil which, in turn, impedes their accumulation in products. It is expected to increase soil fertility, crop yields and obtain environmentally friendly and safe products due to the stable composition of innovative fertilizers.

Agriculture Specialization as the Driving Force for Evolutional Transformation of Neoecology in Noocology

The specialization of agriculture, which has long been regarded as an economic category, is today gaining a new meaning - environmental content, becoming a link between human nutritional needs and the ability of natural ecosystems to address these problems. Purpose. To substantiate the scientific need to "fit in" the specialization of agriculture in the dynamics of natural ecosystems on the complex path of their transformation into agroecosystems. Results. The process of interaction between nature and society (movement) in planetary space-time is represented as two of its main components - nature and society. One of the main causes of the environmental problem lies in the different speeds of development of nature and society. The result of this difference is necessarily "delayed" in the geographical space. Such "prints" were found in the Kharkiv region, where the dynamics of agroecosystems were studied. Because the boundaries of agro-ecosystems are constructive, that is, they are constantly changing, they form their spatial entities, different from administrative boundaries. But in natural ecosystems, adaptation mechanisms are much more sophisticated, primarily because of the multilevel nature of natural communities as opposed to the monoculture practiced in agroecosystems. Adaptive agroecosystems are widely used to solve the environmental problems of modern agriculture, in which widespread consideration, full steam crop rotation, biodiversity increases, manure is completely utilized, biomethods are applied. Actually, adaptation is the search for such forms of agriculture that would meet the natural capabilities of a certain area. Conclusions. In the course of noospherogenesis, the species "Homo Sapiens" has formed its own, no less natural, ecosystem - an agroecosystem that has undergone a complex evolution. Given that agriculture is the closest in terms of material-energy relations to the natural ecosystems of the industry, the search for such forms of management (specialization) that would meet the natural capabilities of a particular area is probably the main task, the solution of which will promote a balanced use of the agro-sphere. From the point of view of the theory and methodology of environmental science, noospheric ecosystems, among which the closest to the natural ones are agroecosystems, have already been formed and can become the object of research that will bring neo-ecology known to domestic ecologists, but not generally observed.
