The Influence of Diesel Fuel and Biodiesel on Soil Microbial Biomass

摘要

Our study aimed to determine the effects of conventional diesel fuel modification with biodiesel addition on the activity of soil microbiota. Diesel fuel, biodiesel and their mixture in a concentration of 5% (w/w) were introduced into soils - light loamy silty sand and light silty loam. Based on the obtained results, reduction in the content of live microbial biomass was found, irrespective of the soil type and contamination. Despite the introduction of biodiesel into soils, inhibition was observed in all examined treatments throughout the entire incubation.
