Abstract

The objective of this study was to evaluate the effect of compost and biochar from trees pruning residues in the presence of plant growth promoting rhizobacteria (PGPR) on some biological properties of calcareous soil. The experiment was carried out in a completely randomized design under greenhouse condition in Rhizobox. The factors included organic matter (biochar, compost and control), microbial inoculation (PGPR bacteria and no microbial inoculation as a control) and soil (Rhizospheric and non-Rhizospheric soil). The organic carbon, microbial biomass carbon, microbial biomass phosphorus, microbial respiration, substrateinduced respiration and phosphatase enzymes in the Rhizospheric and non-Rhizospheric soils were determined at the end of growth period. The results showed that the simultaneous application of organic matter and microbial inoculation increased Soil biological indices significantly as compared to control treatment. Furthermore, the compost treatment increased the microbial biomass carbon, microbial biomass phosphorus, alkaline and acid phosphatase enzyme activity in the Rhizospheric soil by 1. 02, 1. 14, 1. 16 and 1. 10 times, as compared to the ones in non-Rhizospheric soil, respectively. However, the lowest fraction of microbial biomass carbon to microbial biomass phosphorus was observed in Rhizospheric soil of compost treatment. Microbial respiration and substrate-induced respiration in the compust Rhizospheric soil were measured to be 1. 04 and 1. 21 times higher than the ones in the non-Rhizospheric soil, respectively. In general, application of organic matter in the conditions of microbial inoculation compared with non-microbial inoculation lead to improve soil biological properties.
