Abstract The use of organic matter is a highly accepted environmental practice among scientists for the bioremediation polluted soils. In this manuscript we study under laboratory conditions capacity new biostimulant obtained from slaughterhouse sludge in soil by oxyfluorfen at rate 4 l ha −1 (manufacturer’s recommended) over 90-day period. We determined its effects on dehydrogenase, urease, β-glucosidase and phosphatase activities, microbial community structure evolution herbicide soil. Possibly due to high content low molecular weight proteins biostimulant, enzymatic activities were stimulated mainly beginning experiment. Soil biological parameters inhibited oxyfluorfen-polluted At end experiment compared with control soil, β-glucosidase, significantly decreased 47.8%, 50.5%, 36.4%, 45.5% 5 days into experiment, soils inhibition. incubation period concentration had 60% amended biostimulants. These results suggested that higher amounts peptides positive effect remediating Therefore, provides hydrolysis processes used herbicide.
