Rock-phosphate solubilizing bacteria were tested to see how they affect soybean growth in pots. The bacteria were able to break down different types of rock phosphate, with Panthoea sp. and Bacillus sp. being the most effective. Panthoea sp. showed the highest concentration of solved phosphorus with all rock phosphates. When these bacteria were used to promote soybean growth, Panthoea sp. and Bacillus sp. increased growth by 35% and 34% respectively compared to using non-soluble rock phosphate alone. Klebsiella sp. also helped, especially when combined with the other strains. This suggests that using rock phosphate with these bacteria could lead to more profitable and environmentally friendly soybean production.
