THE EFFECT OF HIGH DIFENOCONAZOLE CONCENTRATION ON SOIL MICROBIOTA ASSESSED BY MICROBIOLOGICAL ANALYSIS

In order to improve crop quality and production efficiency, are widely used pesticides. Although they are beneficial in this respect it acts as a stressor on the soil, changing its microbiological balance. The study took into account the determination of physico-chemical parameters (temperature, pH, humidity and content of organic matter), biochemical (enzymatic activities of dehydrogenase, urease, phosphatase and protease) and microbiological (determining the total plate count aerobic mesophilic that develops at 37 ° C, determining the number of colonies of fungi and identifying genres). The determinations were made in a dynamic period of 21 days. Elevated difenoconazole had a deleterious effect on communities affecting soil microorganisms and soil quality
