In model laboratory studies, the effect of veterinary antibiotic tylosin (concentrations of 1, 10, 100, 1000 mg/kg of soil) on the ecological state of dark brown soil under conditions of contamination with antibiotics and the degree of change of microbiological and biochemical parameters was studied. To assess the ecological state, the following biological indicators were studied: from microbiological - the total number of bacteria, the abundances of bacteria of the genus Azotobacter, from biochemical - the activi...

In model laboratory studies of dynamics (3, 30, and 90 days), the effect of veterinary antibiotic tylosin on the biochemical properties of brown forest soil was studied at concentrations of 1, 10, 100, 1000 mg/kg of soil. To study the biochemical properties of the soil, the following indicators were selected: the activity of enzymes of the class of oxidoreductases (catalase, dehydrogenases), hydrolases (invertase, phosphatase), and acidity of the soil (pH). It has been established that contamination of brown fores...
