“…Basal soil respiration of soil microflora provides useful information on the physiological condition of the pedoecosystem even though it is a matter some controversy. This respiratory activity takes into account the use of energy by microflora and expresses the efficiency of organic carbon by soil microorganisms (Ananyeva et al, 2016). In the prsent study, soil enzymes respentative of C and P cycle were selected.…”

Application of chemical fertilizers besides economic concerns has been a reason of environmental and ecosystem degradation, so sustainable organic agriculture is becoming popular in researches and among farming communities. Phosphorus holds second position after nitrogen among macronutrients required for better plant growth and is needed in higher amounts. Meeting this high phosphorus input for better crop yields causes environmental problems like eutrophication, so phosphorus solubilizing bacteria (PSB) and plant growth promoting rhizobacteria (PGPR) are being emphasized to utilize phosphorus fixed in soil layers. This study was carried out to evaluate the effect of PSB on plant growth, soil biological properties including enzymes and soil respiration. Treatments including control, 50 mg kg -1 nitrogen, 50 mg kg -1 nitrogen and 12 mg kg -1 phosphorus applications reduced dosage of nitrogen 25 mg kg -1 with PGPR and 25 mg kg -1 nitrogen along with 0.12 g raw phosphate and PGPR. Results indicated that plant parameters like above and below ground plant biomasses (fresh and dry weight), plant nitrogen and phosphorus content were significantly enhanced in all the treatments when compared with the control. While soil pH in rhizosphere significantly increased with the treatments, bulk soil pH decreased with PGPR treatments when compared with all other treatments. EC values in rhizosphere and bulk soils were not significantly influenced with the treatments. Rhizospheric and bulk soil showed high amount of N, P and organic matter in PGPR treatments. Alkaline phosphatase and βglucosidase activities were found significantly higher in the last treatment than the other treatments. Basal soil respiration was interestingly found higher in control soil but did not differ statistically from the other treatments. Concluding, application of PGPR with lower amounts of chemical fertilizers can reduce the use of chemical fertilizers and has also potential of improving soil health in long term aspects.

Microbial biomass and functional diversity of soil microbial communities in forest soils of the Belogor'e Nature Reserve and in arable soils formed under similar geomorphologic and lithological conditions were determined. We have analyzed the content of carbon of total microbial biomass (C-TMB), of the biomass of living microorganisms by the content of soil phospholipids (C-PL.), and of biomass of microbial cells capable of glucose assimilation (C-SIR). The respiratory response of the soil microbial community to the introduction of different groups of organic compounds-inductors (amino acids and carboxylic acids) was assessed by the method of multisubstrate testing (MST). It is shown that anthropogenic transformation of natural ecosystems results in a decrease in the total microbial biomass, biomass of living cells, and cells that give a respiratory response to glucose. The functional diversity of microbial communities in soils in natural and transformed ecosystems significantly differs. Soil plowing has resulted in a significant decrease in the ability of the soil microbial community to assimilate low-molecular organic compounds. This is most typical for amino acids: arginine, alanine, and glycine (a 2.7-, 5.4-, and 7.1-time decrease, respectively, as compared to native soils). Among carboxylic acids, the decrease in the respiratory response to the introduction of succinic acid is the most pronounced (8.7 times). It has been revealed that the geomorphologic position in natural ecosystems does not affect the biomass of the microbial community and its functional diversity, while the arable soils are characterized by a clear tendency to an increase in these parameters on the lower part of the slope.
