Effect of Bentonite and Barley Straw on the Restoration of the Biological Quality of Agriculture Soil Contaminated with the Herbicide Successor T 550 SE

Environmentally safe ways are sought to prevent the accumulation and accelerate degradation of herbicide active substances in agricultural soil. This study aimed determine effectiveness finely-ground barley straw bentonite mitigating effects soil contamination with Successor T 550 SE. was applied following doses: 0, 0.73, 14.63 mg substance per kg. The spring were used at 10 g/kg. action these additives compared without addition bentonite. application experimental disturbed microbial systems, such as organotrophic bacteria, oligotrophic bacteria their spores, actinobacteria, fungi. A positive response dose a.s./kg observed only for spores bacteria. Further disturbances biochemical properties, i.e., activity dehydrogenases, urease, catalase, acid, alkaline phosphatase, arylsulfatase, β-glucosidase. significant decrease acid arylsulfatase a.s./kg. yield maize decreased analysed plant protection agent. Based on quality index (BA), more effective restoring homeostasis than Both can be successfully improve biological activity. However, mitigation negative objects supplemented straw. improved microbiological properties Barley balance.
