Assessment of agro-ecological composition of gray forest soils under the different agricultural use

The article presents the results of the agroecological composition of soils for different agricultural uses. Under modern conditions of increasing intensification of agricultural production, the agroecological condition of soils is deteriorating, which increases the risk of obtaining low–quality products. Along with this, there are various problems, such as loss of soil fertility, increased erosion, groundwater pollution and environmental pollution in general. Therefore, there is a need for constant monitoring of agroecological indicators of the soil in the conditions of intensive agriculture and horticulture. The great importance is the problem of finding reserves to increase soil fertility and improve their agroecological condition. Therefore, regular testing of soil nutrients and factors that have a major impact on their availability are extremely important to achieve sustainable levels of crop and fruit production. The main purpose of the research was to study and analyze agricultural lands: arable land and perennial plantations and the main agrochemical indicators of the soil of the central part of Vinnytsia region during intensive agriculture and horticulture. The object of research is the soils of agricultural lands used under intensive horticulture and crop production. The subject of research is the agroecological indicators of soil. The research was carried out in the farm of Agro–Etalon LLC in the village of Vasylivka, Tyvriv district. The soils of agricultural lands used under orchards (apple orchard) and agricultural crops (wheat after sunflower predecessor) were studied for comparison. According to the results of soil analysis, it was found that the highest difference in the studied indicators was found in the exchangeable potassium (К2О), mobile phosphorus (Р2О5), which was observed more in the soils involved in horticulture compared to the soils of field crop rotations. Farm soils with different agricultural uses were characterized by lower humus content. The highest difference in the concentration of chemical metals was found for molybdenum (Mo) and cadmium (Cd), which were more in the soils used in horticulture.

Raspberry plant mycobiom under the influence of complex organic-mineral fertilizer viteri in the Central Forest Steppe of Ukraine

The results of research on the influence of foliar treatment of raspberry plants with organic fertilizer VITERI on the population size and species composition of micromycetes in the mycobiome of the rhizosphere and vegetative organs of raspberry plants of Joan J in the Central Forest-Steppe of Ukraine are presented. Microbiological, phytopathological, mycological methods and methods of sampling of raspberry plants during the growing season were used for the study. To determine the effect of VITERI fertilizer on the mycobiota of the rhizosphere and vegetative organs of raspberry plants during plant ontogeny, additional foliar treatment was performed with 1% aqueous solution of VITERI fertilizer. It was found that the population is dominated by fungi of following species: Septoria rubi, West, Aspergillus niger, V. Tiegh, Alternaria alternata, (Fr.) Keissl, Fusarium spp. These micromycetes are producers of mycotoxins and can cause disease in animals and humans, as well as contribute to biological contamination of agroecosystems. During foliar treatment of raspberry plants with VITERI fertilizer, a significant decrease in phytopathogenic load was observed in the phase of intensive fruiting compared to other phases of ontogenesis of raspberry plants.

Features of coarse woody debris volume formation in fresh sudibrova conditions in Zmiini islands tract of Kaniv Nature Reserve

Dead wood (woody debris) is an important component of forest ecosystems. It performs a number of ecological and environmental functions. The article studies the peculiarities of the formation of coarse wood detritus volume and its qualitative structure in forests in the conditions of fresh sudibrova of the Zmiiini Islands tract of Kaniv Nature Reserve. The study of dead wood was carried out in 140-year-old pine-oak forests of natural origin on a permanent sample plot (0.24 ha) by identifying and measuring of standing and lying deadwood components. It was found that dead wood in the forest ecosystem was formed due to the dying of trees of five species: common oak (Quercus robur L.), Scots pine (Pinus sylvestris L.), Norway maple (Acer platanoides L.), small-leaved lime (Tilia cordata Mill.) and common hornbeam (Carpinus betulus L.), and has a volume 56.3 m3·ha–1. Dead wood volume is dominated by standing dead trees — 82.1%, and the share of lying dead wood, respectively, is 17.9%. The main part of dead wood volume is formed by two tree species — common oak and Scots pine, the share of which together is 94.3%. Common oak and Scots pine is characterized by a predominance of standing dead wood, while for other tree species — lying dead wood. In general, dead wood is formed by detritus of I–IV classes of destruction, at the same time detritus of class II decomposition has a significant advantage (70.5%), recently dead wood has a much smaller share (I class, 24.8%), and other classes of destruction have insignificant shares, which together do not exceed 5.0%. No woody detritus of the last (V) class of destruction was detected. Volume of standing dead wood is 46.2 m3·ha–1, and is formed by whole and broken dead trees. In terms of species composition, common oak has a significant advantage (74.5%), Scots pine has a much smaller share (25.1%), and the share of Norway maple is insignificant (0.4%). The total standing dead wood volume is dominated by wood of class II destruction (33.0 m3·ha–1, 71.4%) compared with class I (13.2 m3·ha–1, 28.6%). Lying dead wood is represented by four classes of destruction (I–IV), however, no woody debris was found at the late (last) stage of decomposition (class V). In terms of volume, the second class of destruction has an absolute advantage (6.7 m3·ha–1, 66.3%), much less class III detritus (2.3 m3·ha–1, 22.8%). Lying dead wood of common oak is represented by all four classes of destruction, among which III (40.5%) and I (33.3%) classes predominate. Lying dead wood of other tree species is characterized by the predominance of II or III classes of destruction. The main factors in the formation of woody detritus in the pine-oak forest in the Zmiiini Islands tract could be the impact of adverse climatic conditions (long periods without precipitation in summer), which led to the weakening of individual trees and their death, gusts of wind that broke individual tree trunks, low-intensity snow breaks, and the influence of biotic factors (insects, pathogens).

Settlement characteristics of The Emerald Network "Khukhra" and "Riabyna" objects in Sumy region

The current state of biotope’s vegetation cover by natural and spontaneous origin of the Khukhra and Riabyna river valleys was researched, which are left-bank tributaries of the Vorskla river, as fragments of the preserved landscape within one of the western spurs of the Central Russian Upland. They are listed as perspective objects of the Emerald Network — Riabyna river valley in Sumy region (UA0000427) and Khukhra river valley in Sumy region (UA0000429). The obtained new data on environmental significance are data for the primary database formation in the monitoring organization of these territorial objects. The researched areas are mainly floodplains, small segments of pine terraces and slope’s fragments of these rivers native banks. The presence numbers of biotopes from Resolution 4 of the Berne Convention (C1.222; C1.223; C1.224, C1.32; C1.33; C1.4; C2.33; C2.34; C3.51; D5.2; E2.2; E5.4; F9.1; G1.11; G1.21; G1.22; G1.A4; G1.A1) are given for both explored objects, in addition, for the valley of the Riabyna river are indicated E1.3; E3.4, and for the Khukhra river — C3.4; E1.2. We have not confirmed the existence of such biotopes as C3.4, E1.3, C1.4 for these objects. Also, the presence of Sarmatian-type pine forests (G3.4232) was noted, which are timed to the elevations of pine terraces. Biotopes with constant excessive moisture are ubiquitous in the waters of low-flow artificial ponds. Eutrophic and mesotrophic vegetation of slow-flowing waters often occurs in shallow water along riverbeds. Biotopes groups of dwarf annual amphibious plants were observed only in fragments. Lowland swamps with sedge thickets without stagnant water are widespread in the floodplain, although they occupy small areas. Biotopes flooded pasture and hay meadows are a variety of options coenotic (herbaceous and cereal, wet and moist high-grass meadows). Biotopes of riparian shrubs, willow and willow-poplar floodplain forests are distributed in small fragments in the riverbed of floodplains. Mixed riparian floodplain and gallery forests occur in low-lying areas at the transition from the floodplain to the pine terrace. In general, shrub and forest vegetation on the terraces of these rivers are currently quite limited and fragmentary. Due to the reduction in the use of hayfields, in the floodplain the presence of indigenous forest remnants is quite relevant, which should be a source for their restoration in large areas. Important environmental object in these areas, as part of the Emerald Network is the local population of Ostericum palustre, and in the valley of the Khukhra river discovered a large population.

The assessment of the environmental impact of the waste sludge and hazardous chemicals in the arroyo of Yasynov city of Kamyanske

The main structures of tailings and sludge facilities are tailings and sludge storage facilities, tailings and sludge hydraulic transportation facilities and circulating water supply facilities. Therefore, the assessment of the environmental impact of the sludge storage of waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske is an urgent task for scientists and workers of the ore-processing industrial enterprises. The aim of the work is to assess the impact on the environment of the sludge storage of waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske. The object of the study is the process of environmental pollution due to the activity of sludge from waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske. The research subject is the reduction of the level of environmental pollution during the activity of the sludge storage’s waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske. The initial data of the laboratory analysis of water samples were provided by the laboratory of OJSC Dniproazot. Regulatory and technical documentation is provided by the Department of Environmental Protection of the Department of Ecology and Natural Resources of the city of Kamyanske. The ecological situation in Kamyanske has long been characterized as a crisis. A significant excess of geochemical parameters of some elements in soils was recorded. Particular attention should be paid to the content of Ce and REE in the polymineral substance of tailings. Exceedances of the maximum concentration limits of Ni and Cu in the Konoplyanka River, which flows in the immediate vicinity of the tailings; which suggests an assumption that there is a migration of these elements from the tailings with groundwater and their accumulation near the river.

Ecological sustainability of trees of protective forests against air pollution

The aim is to analyze the resistance of tree and shrub vegetation used to create protective forest belts to air pollution on the basis of experimental studies conducted by other scientists. The research was carried out on the basis of the development of experimental materials on the resistance of tree and shrub vegetation to atmospheric pollution by dust and gases, presented in the works of famous scientists. The obtained results were generalized, the probability of growing gas- and dust-resistant trees in the conditions of climate change in relation to their drought resistance was estimated and the most resistant species of trees and shrubs were recommended. Also identified species of plants that can act as bioindicators of air pollution. Studied by Prysedsky Yu.G. (2014) plant species in terms of resistance to atmospheric pollutants with sulfur, nitrogen and fluorine compounds were divided into four groups: tolerant (resistant), moderately damaged, unstable and with variable resistance. The group of resistant species includes prickly pear, common oak, Tatar honeysuckle and caragana arborescens. These species can be used to create protective forest belts. At the same time, reliable plant indicators of sulfur, nitrogen and fluoride oxides in the air will be unstable plant species — mountain ash and poplar Bolle. Classification of trees and shrubs in terms of their resistance to atmospheric smoke divides plants into three groups: stable, relatively stable, unstable, with the allocation of primary and secondary wood species for forest belts, as well as shrubs. The most resistant to atmospheric smoke are white acacia, elm, white willow, forest pear, poplar, hazel, juniper, forest apple. They can be the main components of protective forest belts in the area of atmospheric smoke. Unstable species — red oak, Scots pine, horse chestnut, viburnum — are bioindicators of atmospheric smoke. There is also a classification of tree species by dust retention M.I. Kalinin (1991). Behind it the most dust of 1 m2 of leaves is retained by white mulberry — 8.1 g, weeping willow — 8.1 g, three-pricked gladiolus — 5.1 g, elm — 4.1 g and field maple — 3.6 g. One tree absorbs the most dust during the growing season in weeping willow — 37.9 kg, Canadian poplar — 34.1 kg, white mulberry — 31.3 kg, ash — 27.1–29.6 kg, maple — 29,2 kg and high island — 24.2 kg. According to Vergeles (2000), poplars have the highest average relative dust resistance — 180 points, common ash — 170, bitter horse chestnut and linden leaf heart — 100 points each.

Assessment of the impact wastewater of dairy farms on soil microbiota

In the production of milk on cattle-breeding farms and complexes large amount of wastewater is formed containing significant numbers of chemicals and is ecologically hazardous source of pollution of water and soil resources. Wastewater of dairy farms contain natural animal excretions, exhaust solutions of cleaning and disinfecting agents, milk residue which is washed off from internal surfaces of milking equipment, residues of feed, litter, dirt, which is washed off during washing of walls and floor of dairy cow house. Since such wastewater contain valuable organic substances they are used to fertilize plants. There are technologies of safe use of wastewater from cattle-breeding farms to fertilize pastures. Also wastewater used as fertilizer in cultivation of sugar beets, tomatoes, cucumbers, spinach, cabbage and the like. It is expedient determination of the influence of wastewater used for the fertilizer of agricultural cultures, on the soil microbiota. After all, soil fertility is inextricably linked with microorganisms that inhabit her. The aim of the work was carrying out of an assessment of influence of wastewater from dairy farms on the soil microbiota. Samples of soil for microbiological studies were selected in 20 centimetre thickness of top layer after application of wastewater of dairy farms. The total microorganism number was determined the method of sowing of soil suspension of corresponding dilutions on nutrient medium of meat-and-peptone agar (MPA). Micromycetes on Chapek medium. The state of soil microorganisms after application in her different doses of wastewater of dairy farms was investigated. It is established, that the total number of microorganisms in soil when accounting 12 days later after application of wastewater in quantities of 500 l/ha exceeded control by 7.4%. At doses of 600 l/ha and 700 l/ha by 9.8% and 12.4% accordingly. 30 days later after application of waste-water the number of microorganisms almost did not differ from control. It was observed that after application of wastewater increase the total number of micromycetes. 12 days later after application of dose 500 l/ha, of number of micromycetes was increased on average by 14,6%; in dose of 600 l/ha by 18.0%; in dose of 700 l/ha — by 19.6%. 30 days later after application of wastewater the total number of micromycetes exceeded control by 1.5%. It is defined, that wastewater of dairy farms in doses of 500–700 l/ha do not exert negative effect on soil microbiota.

Optimization of hydrochemical composition of water in plant growing by structurization method

The aim is to study the change of the main hydrochemical indicators of river water quality during its structuring, regarding the optimization of its composition when used in crop production. Water samples were taken from the Southern Bug River within the Vinnytsia Region. Water structuring was performed before analysis using an Ojas structurizer. Laboratory experiments were performed in the chemical-bacteriological laboratory of KP Vinnytsiaoblvodokanal. Indicators were determined: total rigidity; hydrogen pH; content of chlorides, nitrates, ammonium; electrolytic conductivity, taste and aftertaste. It is established that the hydrochemical composition of water used for irrigation and spraying in crop production and agriculture plays an important role in their efficiency and impact on soils and plants. Among such characteristics of water, the value of water reaction pH, total hardness, concentration of chlorides, nitrates, ammonium and electrical conductivity are paramount. The hydrogen pH of unstructured water was 7.49 pH. Water structuring reduced this figure to 7.17 pH. The total hardness of unstructured water was 4.8 mg/dm3. The structuring reduced the value of its total stiffness to the level of 4.7 mg/dm3. The structuring did not change the concentration of chlorides in water — 45.0 mg/dm3 in both cases. The content of nitrates in unstructured water was 0.50 mg/dm3, and its structuring reduces this figure below the sensitivity of the measuring instrument (less than 0.50 mg/dm3), which is more than 2.0% or more, but this value could not be established reliably due to the technical sensitivity of the device. The ammonium content in unstructured water was 0.07 mg/dm3. During water structuring, the ammonium concentration decreased to 0.05 mg/dm3. The electrolytic conductivity of unstructured water was 563.0 µm cm/cm. During its structuring, it increased to 568.0 µm cm/cm. The taste of unstructured and structured water did not differ and was 1 point. The structuring of river water used in crop production and agriculture causes a decrease in the concentration of ammonium in it by 28.57%; nitrates — by 2.0% or more; reduction of hydrogen pH by 4.27% and total hardness — by 2.08%; increase in water conductivity by 0.88%, which optimizes their characteristics. At the same time, the taste and concentration of chlorides in water do not change during its structuring.
