dc.description.abstractThe effect of different origin organic fertilizers on agrochemical indicators of typical medium-humic chernozem in hazelnut plantings in the conditions of Ukrainian Southern Steppe was studied. There were used cattle manure, chicken droppings, Biofertilizer No. 1 (the combination of sewage sludge, winter wheat straw, phosphate-mobilizing bacteria Microbacterium barkeri), Biofertilizer No. 2 (the combination of sewage sludge, sunflower seed husks, phosphate-mobilizing bacteria Microbacterium barkeri), and native sewage sludge in the study. It was found that different origin organic fertilizers effected on the main agrochemical soil indicators increasing. The content of easy hydrolyzable nitrogen in soil increased from 84.0 mg kg-1 in control up to 98.0 mg kg-1 in the tests, mobile phosphorus - consequently from 138.75 mg kg-1 in control to 306.30 mg kg-1 in the tests, and potassium from 108.40 mg kg-1 in control to 166.90 mg kg-1. In addition, the organic matter content increasing from 3.76% (control) to 4.18% (tests) in the soil was detected. The express biosensor analysis of the fertilized soil showed a variation of the average ecotoxicity indicator from 0.92 to 1.41 which could be classified as a “low” common pollution level. It also detected an elevated zinc content in soil samples fertilized by Biofertilizer No. 1 and native sewage sludge. It proves that organic fertilizers based on sewage sludge applying can allow for overcoming the zinc deficit in Ukrainian soils. The advantages of Biofertilizers No. 1 and No. 2 were identified in respect to other studied organic fertilizers. New biofertilizers using allows soil nutrient content increasing, soil biological activity enhancement, which resulting in improvement in crop yield, and environmental enhancement.eng
