“…Violation of one of the most important laws of agriculture, established in the nineteenth century by the well-known German scientist J. Liebich [17], according to which, in order to preserve the fertility of soils, the farmer is annually obliged to return to the soil that quantity of nutrients taken out from it when harvesting agricultural crops, which causes dehumification of soils and degradation of the soil mantle. Variations in the humus content in the arable layer of soils [16] in three basic soil areals of Ukraine are shown in Fig.…”

“…Because of erosion up to 500 million tons of soil is lost a year in Ukraine. According to expert estimates, there are released about 24 million tons of humus, 0.96 nitrogen, 0.68 phosphorus, and 9.4 potassium [17]. During the twenty-five-year period, the area of the arable land decreased by 1.03 million hectares (the share of the ploughed territory (i.e.…”

“…While implementing differentiation of the territory during the development of projects, a careful approach is necessary to the definition of boundaries between the groups of lands, specification of borders between the massifs of owners and users, correcting them, if necessary, and linking them with the relief of the terrain on the land consolidation principles [16]. It is important to establish indicators of the actual intensity of the soil washout [16] and the degree of the soil erosion hazard [17]. According to expert estimates, the losses of the agricultural product due to the soil erosion exceed 9-12 million tons of grain units per year.…”

During the last 50 years the humus content in the arable layer of the soil in the basic agrarian regions of Ukraine (steppe and forest steppe) has diminished by 15-18 %. Optimisation of the structure of land areas and stabilisation of agricultural landscapes should be based on the soil indicators that ensure conservation of land. It has been substantiated that the contour-meliorative system of land use under the conditions of the development of farming enterprises as the main form of the contemporary land system should be modernised. Primary water collectors should be selected as the object of formation of this system. There are proposed new directions of measures to improve the protection of the soil mantle. The results of the conducted investigation will help stop the soil fertility deterioration process because of excessively high share of arable land and disregard of the ecological and agronomic land-use norms. It is prognosticated that the area of the arable land will decrease by 5.1 mln. ha, but the area of forests and protective plantations will increase by 2.7 million hectares, reaching the proportion of the territory covered by forests to 22 %.

The main ecological challenges of agricultural production of Ukraine in conditions of European integration are considered. The relevance of the chosen topic is justified by the high agricultural potential of Ukraine, which has common values and common interests with the European economic space. This is confirmed by the benchmarking analysis of the security and efficiency of land use in Ukraine among the EU-28 countries. It is known that the life quality of the society depends on the health of the environment, and the intensification level of the agricultural production and processing sector. Studies have shown that Ukraine lags behind the EU countries both in terms of living standards and social development. Therefore, the issue of forming a program to protect the soil resources of Ukraine from degradation and their effective use, with respect to social needs and environmental risks, is an important problem for the European countries as a single ecological system. The authors identify areas for agricultural production intensification in Ukraine, taking into account the requirements for quality and safety of the products. The need for the legal framework harmonization to regulate agricultural production and ensure sustainable development of ecosystems on the principles of a green economy is substantiated.

“…In some conditions, the additional application of organic materials (manure, straw, mass of cover crops, etc.) to fertilize agricultural crops and replenish soils with carbon promotes the domination of organic matter synthesis processes over its mineralization (Raupp J. et al, 2001;Baliuk et al, 2016;Purtova L.N., Kiseleva I.V., 2019). However, the consequences of the impact of agrotechnical technologies on the optimization of mineralization-synthesis processes and humus content are widely separated in time which hinders timely conclusions on the effi ciency of specifi c measures.…”

Focus of mineralization-synthesis processes of the organic matter in the leached chernozem while cultivating potatoes on different fertilization backgrounds

Aim. To investigate the focus of the mineralization–synthesis processes in leached chernozem while cultivating potatoes in different fertilization systems, ensuring different supplies of raw organic matter into the soil. Methods. Field experiment, gas chromatography. Results. The study of emissions of nitrous oxide and carbon dioxide from the soil followed by the calculations of the specifi c losses of N-N2O (g/kg C-CO2), depending on fertilization system and in comparison with the indicators of the “reference” soil, provide an opportunity for rapid determination of the focus of the mineralization-synthesis processes in the organic matter in agrocenoses. The use of exclusively mineral fertilization systems results in the highest specifi c losses of N2O as the increase of the applied fertilizer doses initiates the mineralization processes in the soil. The combination of mineral fertilizers with raw organic products (5 t/ha straw and 13 t/ha of lupine cover crop) signifi cantly improves the situation. At the same time, in experiment with the lowest (N40P40K40 kg/ha) and medium (N80Р80К80 kg/ha) doses of mineral fertilizers the balance of mineralization-synthesis processes of organic matter was observed. The highest rate of mineral fertilizer dose in the experiment (N120P120K120 kg/ha), even in combination with the raw organic material, activates mineralization processes. With the use of manure, as well as upon its combination with the lupine cover crop and low doses of mineral fertilizers, the optimization of nitrous oxide and carbon dioxide emissions is observed. Conclusions. The use of solely mineral fertilizers in the technology of potato cultivation is inappropriate in terms of environmental reasons. The combination of mineral fertilizers (not exceeding N80Р80К80 kg/ha dose) with straw and lupine cover crop ensures optimization of the processes of mineralization-synthesis of organic matter. Moreover, the optimization of biological processes in the soil was observed in experiments with the use of manure, its combination with lupine cover crop and low doses of mineral fertilizers. The calculations of the indices of mineralization-synthesis of organic matter, considering the emission factors of N2O and CO2, obtained with the use of modern high-sensitivity gas chromatographic methods, allow to determine the focus of biological processes in the soil, depending on fertilization system, and to estimate ecologic sustainability of types and doses of fertilizers.
