Abstract

The Organic matter and microorganisms affect the solubility and mobility of nutrients in the Rhizosphere and so improve their bioavailability. In order to evaluate the effect of biochar, pruning waste compost of apple and grape trees and plant growth promoting rhizobacteria (PGPR) on ability for macronutrient uptake in calcareous soil, an experiment carried out in a completely randomized design under greenhouse condition in rhizobox. The factors including: the Organic matter (pruning waste biochar, pruning waste compost and control), microbial inoculation (PGPR and control (without microbial inoculation)) and soil (Rhizosphere and non-Rhizosphere soil). At the end of the growth period, pH, electrical conductivity (EC), Organic carbon and availability of macronutrients in the Rhizosphere and non-Rhizosphere soils and concentration macronutrients in the plant were determined. The results showed that the highest pH was in biochar (7. 88) without microbial inoculation. The amount of EC, N, P and K in compost treatment with PGPR inoculation was significantly higher than other treatments. The highest organic carbon was observed in the control of compost, which increased to 78. 9% in comparison with microbial inoculation treatment. Compost in provided more contents of EC, OC, N, P and K in the Rhizosphere and non-Rhizosphere comparison with biochar, it indicating higher EC, OC and nutrients content in the compost that was used. PGPR inoculation increased the availability of P and K by 1. 21 and 1. 26 times in non-rhiozosphere soil, compared to the Rhizosphere. However, EC, OC and N values in the Rhizosphere soil of the PGPR inoculation treatment were 1. 22, 1. 24 and 1. 19 times higher than non-Rhizosphere soil, respectively. The higher uptake of N, P and k by plant in inoculum of PGPR biochar increased 48. 60, 32. 55 and 32. 16 % compared to the control, respectively. In general, according to the results of this study, it seems that the use of PGPR and appropriate amounts of biochar and compost, while increasing the macronutrients availibity in the soil, improve the uptake of these elements for plants.
