N. Sokolovski" popup.description2 The object of investigation - the content of biologically available forms of micronutrients in soils, the trace elements' content in plant material (grain). Objective - to develop a system for soil quality evaluation by natural micronutrient content taking into account micronutrient intake by major crops , including clarification of pre-designed specifications. Research methods - universal general scientific methods, methods of theoretical analysis, a systematic approach, comparative analysis, the software method. Results - the method of normalization of soil trace -metals (Zn, Mn, Cu, Co, Fe) is carried out. A gradation of soil by natural content of trace elements is the result of calibration of available for uptake by plants trace elements contents in soils of different buffering capacity. Calibration is made on the basis of experimental data using the method of determination of fuzzy linguistic variable ordinal scale for the quality and parametric statistics. The groups of crops by consumption and removal of trace elements are determined. A system for the evaluation of agricultural soils by the content of natural available (such seized ammonium acetate buffer, pH 4.8) trace metals (Zn, Mn, Cu, Co, Fe) for crops growing. Regulations for optimum natural content of trace elements mobile forms in soils with low, medium and high buffering capacity for crops based on the mathematical treatment of the data on the array of soil Ukraine mobile forms of trace elements (1100 samples) and data series of stationary and vegetation experiments conducted in different climatic zones of Ukraine are proposed. A guide for the evaluation of soil quality by the trace elements content is carried out. Novelty - normalization of trace elements content in soils is carried out considered their buffering properties and features of the absorption and accumulation of trace elements by grains. The results of research are planned to introduce in the State Institution "Soils Protection Institute of Ukraine" and its affiliates. Efficiency - expected cost savings businesses in the crop of 10-20 €/ha due to reduced need for fertilization by the spatial distribution of rational crop rotation and formation in accordance with the needs of microelement nutrition of crops and the actual supply of arable soils by micronutrients. At the same time expected to reduce the cost of crop production by 5-10% and increase its quality. Field of application is agriculture.
