Bacillus megaterium

High-Performance Biofertilizer with Advanced Phosphate Solubilization

Bacillus megaterium is an advanced biofertilizer and plant growth-promoting rhizobacterium (PGPR) specifically selected for its exceptional ability to solubilize phosphorus, enhance nutrient uptake, and improve soil fertility. This powerful agricultural microbe transforms insoluble phosphorus compounds into readily absorbable forms, leading to vigorous root systems, improved plant health, and increased crop productivity.

Beyond phosphorus mobilization, Bacillus megaterium actively supports the production of beneficial enzymes, amino acids, and plant hormones (phytohormones), promoting healthier soils and more resilient crops. Ideal for use in row crops, orchards, vegetable production, greenhouse farming, and organic agriculture, it significantly reduces the need for synthetic fertilizers. Key benefits include:

Enhanced phosphate solubilization
Improved nitrogen cycling
Natural plant health & defense support
Plant growth stimulation (phytohormones)
Stress tolerance (salinity, drought, heavy metals)
