Abstract

ABSTRACT: The objectives of this research were to evaluate the rhizospheric effects of bean ( Phaseolus vulgaris ) on phosphorus (P) availability and dissolved organic carbon (DOC), microbial biomass carbon (MBC), microbial biomass phosphorus (MBP), alkaline phosphatase (ALP) and P in the particulate fraction (PF-P) in some calcareous soils under rhizobox conditions. The results showed that DOC, MBC, MBP and ALP strongly increased in the rhizosphere soils compared with the bulk soils ( p < 0.05). Also, the amounts of PF-P and P extracted with different tests in the rhizosphere were lower compared to the bulk soils ( p < 0.05). The correlation studies showed that plant indices (dry yield and P uptake) had a positive relationship with Olsen-P, MBP, DOC, ALP and PF-P in both the rhizosphere and the bulk soil. Therefore, bean rhizosphere caused increases of DOC, MBC, MBP and ALP and decreases of available P and PF-P in the studied soils. In addition, the results of this research showed that the Olsen-P method and MBP and PF-P could be used to estimate bean-available P in the studied calcareous soils.
