AGSO Microbial bio fertilizer Phosphate Solubilizing Bacteria (PSB) applied to soil, these bacteria multiply rapidly and colonize the root zone (rhizosphere), creating a continuous phosphorus-releasing system that works throughout the growing season. This provides plants with a steady supply of this critical nutrient exactly when and where they need it most.
PSB Comprehensive Benefits for Soil and Plants
- Enhanced Root Development, creating stronger plants with improved nutrient absorption capabilities.
- Improved Soil Health, enhance soil structure, increase organic matter, and promote beneficial microbial diversity.
- Increased Crop Yields, 15-25% yield increases across various crops treated with AGSO Bio fertilizer.
- Long-term Cost Efficiency, the progressive improvement in soil fertility reduces input requirements over time, while increasing yields provides better returns per acre.
How Phosphate Solubilising Microbes Work
- Secrete organic acids that lower soil pH around root zones.
- Produce phosphatase enzymes that break down organic phosphorus.
- Create microenvironments that enhance nutrient availability.
- Convert insoluble phosphate forms (calcium, iron, aluminum phosphates) into soluble forms.
