Sloboda P. Agrochemical estimation of fertilizer artichoke on a gray forest soils of the Western steppes of Ukraine

Object- processes, properties and performance and nutrient regime of the biological status of the gray forest soils, as well as the formation of Jerusalem artichoke productivity under different fertilization systems. Purpose - to justify a rational system of artichoke fertilizer to increase productivity and improve fertility agrocenosis gray podzolized soils of Western Forest Steppe of Ukraine. Methods - field, laboratory and analytical, microbiological, statistical, computational. Theoretical results - The theoretical basis of rational fertilization systems artichoke, established the basic laws of its growth and development under the influence of different modes of mineral nutrition, proposed a scientific solution to the problem of improving agro-ecological condition of gray forest soils due to the rational fertilization. An effective system of fertilization artichoke, which provides the highest rates of biomass accumulation and productivity agrocenosis; The expediency of the introduction of fertilizer artichoke, which ensures high economic efficiency and bioenergy. Practical results - proved high efficiency of organic-fertilizer system with the sharing of microbiological fertilizer preparations made on the basis of effective microorganisms of the soil, in the formation of human agrocenoses energy and energy resource growing area. Novelty - functional and modal stability of soil is allocated, presence of feed-forwards and feed-backs between them and their value for normalization is determined; principles of soils' classification on their stability to heavy metals are developed and three basic classes is allocated; principles of determination of aggregate stability of a thin disperse part of soil, and change of this property under effect of external factors are fixed; the methodology of a regulation of soils' carbohydrate pollution is developed; necessity of transition to soil-adapted and functionally-differentiated systems to an estimation of pollution is proved. Degree of application - rational fertilization system introduced on the area of 54.1 hectares in farms of Lviv and Volyn regions. The field is agriculture.
