At the present stage of farming the main problem is not only to obtain high yields of crops, but also the preservation of soil fertility at the proper level. To solve this problem we need to possess reliable information about ecological and agrochemical status, a quality assessment of soils of the region. The source of such information are the results of scientific research "Agrochemical certification of agricultural land", which was conducted from 01.2006 to 12.2010. The object of the study was the soil for agricultural purposes agroformations of different ownership forms. The aim is to state control over the change in indicators of soil fertility and pollution of their toxic chemicals and radionuclides, rational use of agricultural land. Field studies were conducted with the "Methods of agrochemical certification of agricultural land appointment". Kyiv. - 2003. Analytical work was carried out with instruments of native and foreign production according to existing procedures in the center, as displayed in the final report. As a result of the test lands, security elements of plant nutrition is not enough. On the content of humus, soil areas are low and the average availability whose content ranges from 1.4 to 3.6%. Availability of easily hydrolyzable nitrogen - is very low and low (54-147 mg/kg), moving phosphates - low, medium (22-92 mg/kg), exchangeable potassium - from low to high (53-168 mg/kg). The reaction of soil environment varies from very acidic to neutral (pH 4,1-7,0). On soil types most common soil areas are light gray and gray podzolized, dark gray podzolized, soddy gley carbonate, chornozem, podzolized and other, who occupy a small area and do not have a significant impact on economic and business activities. Light gray podzolized and gray podzolized soils occupy 21.6% of the surveyed areas. Humus content varies from 1,4 to 2,5%, which corresponds to the low and medium security. Availability of easily hydrolyzable nitrogen is 55-147 mg/kg (by the Cornfield's method) of soil and relates to very low supply. Mobile phosphates and exchangeable potassium are respectively 2-61 and 53-168 mg/kg of soil (by Kirsanov method). The reaction of soil solution (pH salt - 5,1-6,3) - slightly acidic, which is close to neutral and neutral Dark gray podzolized soils provide elements of plant nutrition somewhat better than light-gray and gray podzolized and occupy 18,9% of the land, the content of humus is 1,7-2,6%, of easily hydrolyzable nitrogen - 83-137mg/kg of soil, moving phosphates - 24-66 and exchangeable potassium - 54-143 mg/kg of soil (by Kirsanov method) and pH salt - 5,3-6,3. Soddy gley carbonate soils on the content of humus are of the lower and medium security (1,8-2,5%), the content of easily hydrolyzable nitrogen - to very low and low supplied (86-131 mg/kg of soil). Moving phosphates and exchangeable potassium security is better than in light-gray and gray soils. The reaction of soil environment is close to neutral and neutral. Podzolized chornozems occupy 16.3% and are better supplied with nutrients. Humus content varies from 2,1 to 2,7%, the content of easily hydrolyzable nitrogen 88-103 mg/kg of soil, available phosphorus 24-67 mg/kg of soil, exchangeable potassium - 53-138 mg/kg of soil and is close to neutral and neutral reaction of soil (pH salt - 5,5-6,3). Grey podzolized, meadow-chornozem, meadow and meadow-swampy soils occupy a small area, the security elements of nutrition in which, to some extent, is lower and have not significant impact on gross indicators of agricultural production. Materials of ecological and agrochemical certification of the fields can be used in the analysis of the economic activity of agricultural enterprises, pieced lands of collective farms, the lands, assigned to farmers under the collective gardens and orchards, while setting tax and land rent, as well as in predicting the fertilizer norms on projected harvest of each crop rotation field. The agrochemical and agrotechnical conclusions and proposals are implemented in the agriculture of the oblast. Product Description popup.authors Бужак А.В. Денисюк М.В. Дутка Ф.І. Лободовська М.М.
