Tsiuk O. Theoretical grounding developing system of ecological agriculture in Forest-Steppe zone of Ukraine

Object of research - the process of changes agro-chemical, biological, agro-physical and water-physical parameters of soil fertility, phyto-sanitation state of the crop rotation, crop yield and quality effected by systems of industrial, ecological and biological farming. The purpose of research is to develop the theoretical approaches of ecological farming in the Forest-Steppe region of Ukraine, based on bioclimatic potential of agrolandscapes, the economical profitable soil usage under the extended soil reproduction and ecological safety of environmental. Firstly, for the field rotation in the Right Bank of Forest-Steppe region Ukraine, was technologically, economically, energetically, ecologically valued and tested the influence of tree ecological farming levels: industrial, ecological, biological. The ecological farming system based on plowing - minimum soil tillage was developed and recommended, that revealed the adequate biological land potential at the level of 10.6 ton/ha of fodder units, with energetically effective coefficient - 6.3 and 96% - profitability. Scientific achievements were implemented in the private and cooperative farms on 15652 ha - in Vinnitskiy district, 2965 ha -in Kirovogradsiy district. Field of application - agriculture.
