This study aims to determine the effects of comboutea and lyophilized comboutea culture on soil some soil biological features. This study was carried out on 2 different soils as a pot experiment in the greenhouse. 4 doses of comboutea (0, 10, 20, 30 ml/ pot) and 4 doses of lyophilized comboutea culture (0, 0.25, 0.50, and 0.75 mg/pot) were applied on the soils with 4 kg soil in apiece pot. At the end of the experiment, basal respiration (BR) and microbial biomass carbon (MBC) analyzes were made in the soils taken from the pots. According to the analysis results, it was observed that upregulation in the amount of comboutea and lyophilized waste of comboutea culture caused an improvement of BR and MBC of soils based on the soil texture.
