Surveyed 427 farms of the region, selected 66.83 thousand soil samples and executed 379.03 thousand of tests. Based on materials from agro-chemical survey of 24 667 is composed of agrochemical passports. The bulk soils in the region characterized by higher and high humus content. Thus the area with higher content is 508.5 thousand hectares, which is 38.0%, high - 563.8 thousand hectares, which is 38.9 % of the total area. The rate decreased over in the last 5 years by 0.05% from 3.88% to 3.83%. By providing mobile soil phosphorus is dominated by middle-and high content. Area of the soil with higher connect is 731,6 thousand hectares, which is 56,0 %, with middle – 353.4 thousand hectares, which is 27,0 % of the total area. The average content of mobile phosphorus in the whole region on the results of the last 5 years increased by 6 mg / kg. By provision of exchangeable potassium is dominated by soils with a high and higher connect. Area of the soil with high connect is 653.0 thousand hectares, which is 50,0 %, with higher connect are 435.8 thousand hectares, which is 33.4 % of the total area. The average content exchangeable potassium in the last 5 years has increased by 20 mg / kg (from 122 to 142 mg / kg soil). The investigation found no soil contamination above ACB pesticide residues. The content of radionuclides in arable land area has not changed significantly. In general, soils are characterized by high potential area of fertility, which helps to ensure a sustainable high crop yields. Based on materials agrochemical certification of specialists of the center conducted a qualitative assessment of ecological and agro-chemical state of agricultural land in the Dnepropetrovsk region score on their agrochemical properties relative to reference values. On average in the area of the soil are environmental agrochemical state - 54 points relative to the reference soil. According to the research created a computerized information database of core indicators of soil fertility by district area. Each year research project takes the form of a scientific report, published in scientific journals and recommendations for the rational use of fertilizers and reproduction of soil fertility.
