The article shows the agreed dynamic variation of physical properties and phytoindication assessments of the ecological regimes of the Nikopol manganese ore basin technosols by means of principal components analysis. The study was conducted at Dnipro State Agricultural University Research Center in city Pokrov during 2012-2014. Data on the aggregate structure was processed by composite analysis. The application of the log transformation of aggregate soil particle distribution data allowed to obtain new non-correlated variables that are able to reproduce the matrix of distances between sampling points that are most correlated with other environmental properties of technosols. Results of principal components analysis allowed to reproduce initial variables by seven principal component with eigenvalues dominated one. These components describe 72.4% variation feature space. The principal components are the integral variables that are sensitive to the dynamics of agreed environmental properties of technosols and have a differential ability. Each of the principal component indicates features of technosols types or a particular group. By their nature, certain selected features directly characterize the soil in the context of its importance as a habitat of living organisms. Also important group of signs are phytoindication assessment of the ecological regimes. Variation of edaphic characteristics as well as environmental assessments are based on the properties of vegetation, synchronized with each other. Such synchronization enables a more profound interpretation of environmental indicators that have independent significance. [ABSTRACT FROM AUTHOR]

The article examines the hypothesis that the structure of the soil-like body in zero-point of its existence directs the dynamics and trajectory of soil formation. To test the hypothesis at the Dnepropetrovsk State Agricultural and Environmental University science satiation the field experiment was laid out lizymetres, each contain a constructive combination of rock or chornozemlike mass. It is shown that the design of the soil-like body in zero-point of its existence controls the dynamics and trajectory of soil formation. Philip equation was modified to more suitable simulate the infiltration process in tehnozems which allows to accurately describe the water absorption process at the infiltration and filtration stages. The nature of the underlying rocks located at a certain depth impacts significantly on the process of soil formation within the whole soil profile. Underlying rock layer regulates the processes of the tehnozems contact with the environment, as well as determining the intensity profile migration of moisture and dissolved salts. The presence of water resistant biogenic origin aggregates smoothes the varying density clay soils resulting from swelling and shrinkage processes that can maintain stable structure of the pore space. As a result, the soil after reclamation phase gets such features as reduced infiltration rate, but increased level of filtration. Optimal values of sorptivity and filtering corresponds closely with relevant properties of soil that can be investigated using indicators of the soil mechanical impedance. Uniformity preparation and impermeable aggregate structure determines the optimal functional modes of the tehnozemes. [ABSTRACT FROM AUTHOR]

The article considers modern directions of expansion of the raw material base in the production of mixed fodder for egg chickens. One of the most important conditions for the modern production of high quality fodder, protein concentrates and premixes is the search and use of new raw materials of plant and animal origin. At the same time, the share of grain in these products is not more than 50%, and in the recipes of the feed industry of the leading countries 20-30%. Modern technologies provide the use of any feed, as an important raw material for the feed industry, derived from waste and by-products of food industries, which are characterized by high fodder quality at a low cost. Domestic producers of feed are now forced to solve the problem of optimizing the use of cereals, in particular, to reduce the content of cereals in the formulation of feed and the content of fillers in the formulation of premixes. The problem of expanding the assortment of feed resources in the production of mixed fodder, premixes, and the use of cheaper fodder raw materials to reduce the cost of finished products is acute. For the cost-effective growth of egg chickens, high-quality feed is required, selected for each species, taking into account the age and physiological state of the bird [1]. In recent years, the production of eggs in Ukraine remained at 19 billion units. a year, but starting from 2015, we see a significant decline. A similar decline in production is associated with a decrease in the number of egg chickens. If we consider the production of eggs in terms of the categories of enterprises, it can be noted that in the households the volume of production in recent years is also decreasing, but overall, the rate of decline in production is much slower and smaller than that of agricultural enterprises [2]. In order to expand the raw material base of feed production and provide the necessary level of productivity of egg chickens, the introduction of corn-phosphate feed (KKFK) concentrate in feed was proposed. The features of the compounding formulations were studied on the control and experimental recipes. The formulation of mixed fodders with the use of KKFK for balanced diet of chickens has been developed, an increase in the level of exchange energy, nutritional value of feed and its profitability has been established.
