Description
Summary:The aim of our experiment was to determine the effect of heating oil application on the count of microorganisms and some physicochemical properties of limed and lime-free soil and soil sown with yellow lupine of the Markiz variety and unsown soil. The results obtained indicate that heating oil deteriorated the physicochemical properties of the experimental soil (acidification, decrease in the total alkaline exchangeable cations, soil exchange capacity and alkaline cation soil saturation). At the same time, it stimulated, to a different degree, the multiplication of soil microorganisms, especially oligotrophic bacteria (10-fold) and bacteria representing the genera of Pseudomonas spp. (8-fold). Lime application and cultivation of yellow lupine had a positive effect on the physicochemical properties of soil and stimulated the growth of Azotobacter spp.
