Assessment of phytomeliorative efficiency of Kochia scoparia (L.) schrad.

  Phytomeliorative efficiency of the annual grass Kochia scoparia (L.) schrad was assessed. The experiments were conducted on the solonetz of the southern chernozem. It was revealed that the application of high doses of sewage sludge (from 50 to 200 t / ha) contributed to an increase in the yield of green mass of Kochia scoparia by 133–362%. After the combined action of annual grass crops and organic fertilizers, the soil density decreased from 1.47 g / cm3 in the solonetz to 1.25 / cm3 in the variant with a dose of 200 t / ha, water resistance for three years of research increased by 37.8%, water permeability increased by more than 5 times.
