Influence of traditional and perspective fertilizers on the activity of сs137 in drained sod-podzolic soils

М. Tаrariko, G. Lychak

Keywords: dried sod-podzolic soil, grain-potato crop rotation, fertility, humus, phosphorus, potassium, radiocaesium СS137, polymineral fertilizer

Goal. To evaluate the long-term effects of the traditional organo-mineral system of fertilizer of grain and potato crop rotation on the fertility of drained sod-podzolic soils. Determine the influence of fertilizers on the activity of Сs137, in particular, to establish the effectiveness of the application of promising polymineral liquid fertilizer «MacroMic» by its foliar application during vegetation from the point of view of increasing yields and decreasing of Сs137 in the yield of plants.

Yields of haricot beans depending on soil tillage, mineral fertilizers and row spacing under irrigation

V. Ushkarenko, S. Lavrenko, D. Maksymov

 Keywords: haricot bean, grain yield, soil cultivation, fertilizers, row spacing, irrigation

 Actuality. Nowadays there is a tendency to change agricultural producers attitude to leguminous crops. First of all it concerns winter pea, chickpea, lentil and haricot. At the moment sown areas under haricot are being expanded mainly at the expense of the private sector. The industrial cultivation is insignificant and does not extend, mainly, because of too little knowledge in haricot cultivation technology elements in different agro-climatic zones.

Justification of the resource-saving system of arable farming when providing inter-sectoral optimization of reclamated agro-ecosystems of Polissya

Y.Tarariko

Keywords: Reclaimed agroecosystems of Polissya, simulation modeling, sectoral structure, enterprise, farming system, economic efficiency

Goal. To highlight the peculiarities of the formation of the cycle of organic carbon, nitrogen, phosphorus and potassium in different branch structures of agrarian production and to substantiate of the resource-saving organic farming system, which will ensure reproduction of the fertility of drained sod-podzolic soils. Formation of multisectoral agrarian production allows to achieve a high level of recirculation of biogenic elements, significantly reduce compensatory doses of mineral fertilizers and ensure of no-deficit organic carbon balance. In order to carry an accurate quantitative assessment of these opportunities concerning of diverse agroecosystems in the conditions of the Right Bank Polissya, the research task was to evaluate the cycle of nutrients in different scenarios of the development of a typical agricultural production.

Water quality patterns over the length of the Dnieper river

V.Vyshnevskyi, S.Shevchuk, O.Kravtsova

 Keywords: the Dnieper River, water quality, reservoirs, Bortnitska water treatment station

 Introduction. The Dnieper River is the most important river of Ukraine, the water of which is used for many purposes, in particular, for drinking water supply.  Human activity has an important impact on the Dnieper River, the main factors of which are the regulation of runoff and sewage water. In addition to that, the quality of water depends on some natural factors, among which the water runoff is the most significant one.

Patterns of profile variability of drained peat soil properties

S.Kolomiyets, S.Kika

Keywords: physical and water-physical properties, profile variability, structure of peat pore space

Actuality. The problems of efficient use of drained peat soils are increasingly becoming the focus for meliorators, ecologists and the public in Ukraine. The purpose of the article is the publication of new knowledge on the patterns and mechanism of transformation of physical and water-physical properties of peat soils using new methods of laboratory research that will promote harmonization of productive and ecological functions of drained peatlands.

Water consumption of highly productive forage crops on drained peat soils of the western part of Ukrainian Polissya

S. Kika

Keywords: drained lands, peat soils, vegetative period, water consumption of forage crops, highly productive forage crops.

By the results of the conducted field researches it is established that barnyard grass, amaranth and fodder beans during the vegetative period use moisture in unequal quantity, and on the volume of their water consumption it is possible to allocate three periods: I – from emergence of shoots prior to intensive growth, II – a phase of intensive accumulation of organic substance and the maximum consumption of moisture, III – from the beginning of aging and withering of leaves. During the first period of growth of culture evaporates moisture a little – 20-30% all used for vegetation, during the second period – 50-60, and at the end of vegetation – 15-20%. The maximum consumption of moisture is noticed during intensive accumulation of organic substance and it is mostly the period for the end of June, within July.

Method of the calculation of vertical drainage with the syphone water intake of infiltration water

P.Khoruzhyi, V.Levytska

 Keywords: vertical drainage, well, siphon drainage, water intake collector, , hydraulic supports, infiltration water

 The efficiency of the operation of vertical airlift drainage systems of the left bank of the Kakhovsky reservoir, namely the area of the Kamyants’kyi Pid is analyzed. It has been established that airlift drainage systems are not effective due to the constant decrease in well discharge as a result of the colmatation of well filters by flocculates of trivalent iron hydroxide, which is formed as a result of the interaction of air pumped by compressor stations to the wells and local water, which contains colloidal iron bicarbonate as well as due to the low efficiency of airlift plants. It is proposed the measures to increase the efficiency of anti-filtering facilities operation by converting the airlift system for water intake from drainage wells to the siphon system.
