| Popis: | The results of the current research determined that the most significant impact on the optimization of the physicochemical properties of the meadow-chernozem soil was exerted by the aftereffect of urban sewage sludge in combination with zeolite-containing agricultural ore. The cation-exchange capacity against their background exceeded the initial values by 4.76-5.59 meq/100g of soil, total exchangeable bases by 6.37-7.51 meq/100g of soil, the pHCl value by 1.10-1.38 units The total productivity of crops against the background of a unilateral aftereffect of urban sewage sludge was higher than the control by 1.48-3.59 t/ha, and against the background of their complex aftereffect with zeolite-containing agricultural ore by 2.89-5.85 t/ha. |
