Kalinichenko A. Scientific foundation of modeling of ecological balanced agroecosystems of Ukraine

The dissertation is devoted to theoretical substantiation and practical devices elaboration of forming of the ecological balanced development of agroecosystems by means of the zonal ecological mathematical models introduction. The models of ecological safe running of agricultural production are created on the base of the information about the condition of agrolandscapes, ground using systems, technologics of agricultural production running, condition of biota, taking into account soil-climate conditions and planned productivity of agrophitocenoses. The aim of creation above mentioned models is the optimization of agroecosystems and prognosing of their further development on the base of protection of soils the using of agrobiotechnologies, new sorts and gibreeds of agricultural plants, animal breeds, controlling of enthomo-fauna, deceases distribution control over the weeds, etc. Elaboration of the op-timal variant of the model gave the possibility of maximum supplying of the restoration of nature resources while having minimum expenses and also planning and supplying of harmonic development of the components of the agro-sphere in purpose on high effectivity of management achieving while mini-mum sufficient using of the industrial originated resources. Restoration of the soil fertility for increasing of the productivity of agricul-tural cultures should be managed by the costs of minimization of mechanical cultivation of the soil and using of biological ways of the intensification (ma-nure, peat, punch, ciderates, straw, mashed stalkes, mule of the ponds, organic wastes). For increasing of the economical effect from using of organic, mineral fertilizers and other ways of the intensification, stable control over the nutritious regime, pollution of the soil and the plant condition should be managed. Taking into account the modern conditions, the monitoring should be used in every farm of Poltava region, and it's results must be announced every year.
