INTERACTIVE EFFECTS OF SOIL ORGANIC MATTER FRACTIONS AND RHIZOBACTERIA ON SOIL FERTILITY

Abstract

The rhizobacterial species (Rhizobium spp. and Bacillus spp.) used in a study to evaluate their impact on soil organic matter (SOM) fractions, the activity of microbial communes and specifically the nutrient dynamics. The applied Rhizobium spp. strains suggestively influenced three fractions of organic matter i.e., particulate organic matter (POM), dissolved organic carbon (DOC), and humic substances (HS). The other major fraction Microbial biomass carbon (MBC) was also pointedly enhanced by both bacterial treatments. The other soil characteristics i.e., pH, electrical conductivity (EC), N, P and K had been also highly improved, particularly in Rhizobium-treated soils. These conclusions underscore the role of rhizobacteria in cultivating soil quality, augmenting carbon sequestration, and auxiliary sustainable agricultural practices. Rhizobium spp. was predominantly effective, signifying its utility as a auspicious microbial amendment for soil fertility enhancement.
