Role of microbial solubilisers on major nutrient uptake - A review

Abstract

The poor productivity of crops has always been primarily attributed to imbalance application of nutrients and use of traditional varieties. Significant increase in seed P of different legumes due to co-inoculation of Rhizobium and PSB over control have been observed. Production of growth-promoting substances and high colonization ability of rhizobacteria such as Pseudomonas because they enhance the nitrogen fixation of soybean when co-inoculated with Bradyrhizobium japonicum. phosphorus (P) is a major growth-limiting nutrient, and unlike the case for nitrogen, there is no large atmospheric source that can be made biologically available. Root development, stalk and stem strength, flower and seed formation, crop maturity and production, N-fixation in legumes, crop quality, and resistance to plant diseases are the attributes associated with phosphorus nutrition. In light of several literature this paper has briefly reviewed the role of microbial solubilisers on major nutrient uptake.
