Q: What is Bacillus coagulans and what role does it play in agriculture?

A: Bacillus coagulans is a lactic acid-producing, spore-forming bacterium used as a soil probiotic and microbial biostimulant. It promotes root development, enhances nutrient solubilization, and supports microbial diversity in the rhizosphere. Its robust spore structure and metabolic versatility make it suitable for improving plant vigor and soil function in diverse farming systems.

Q: How does Bacillus coagulans enhance nutrient availability for crops?

A: This strain produces lactic acid and other organic acids that lower rhizosphere pH, helping solubilize phosphorus, iron, zinc, and other micronutrients. As a result, nutrient availability improves, especially in high pH or compacted soils where locked-up nutrients are otherwise inaccessible.
