Evaluating the phosphate solubilizing ability of novel Bacillus sp. strains and their effects on corn production

This study investigated the effects of two phosphate solubilizing bacteria (PSB) isolates, Bacillus sp. strain E1 and G4, and three fertilizer types on soil properties, corn growth, and yield. The results showed that PSB E1 increased soil organic matter (SOM) and available phosphorus, while G4 enhanced exchangeable potassium and cation exchange capacity (CEC). Organic fertilizers improved soil fertility, while inorganic fertilizers had a different impact. The combination of PSB G4 and organic fertilizer produced the highest yield, while PSB E1 combined with fertilizers boosted crop growth. The interaction between PSB strains and fertilizers played a significant role in determining soil properties, corn growth, and yield.
