Phosfix
Phosphorus Solubilizing Bacteria (Bacillus megaterium var. phosphaticum)
Phosfix
Biofertilizer that releases phosphorus already trapped in the soil by earlier fertilizer applications, cutting the need for additional phosphatic fertilizer while improving soil quality.

Key Advantages
Why Phosfix Works
The key benefits that set Phosfix apart in the field.
Solubilizes 15–20 kg/hectare of previously fixed phosphorus in the soil
Reduces phosphatic fertilizer costs by up to 25%
Improves soil texture, organic matter content, and microbial population
Enhances root proliferation alongside nutrient release
Mode of Action
How It Works
See exactly how Phosfix targets pests in 3 simple steps.
Organic acid production
Bacillus megaterium var. phosphaticum secretes organic acids such as succinic acid in the rhizosphere.
Phosphorus solubilization
These acids dissolve fixed, insoluble phosphorus compounds accumulated from earlier fertilizer use.
Root zone availability
Solubilized phosphorus becomes accessible for direct root uptake, supporting flowering and fruiting.

Application Guidelines
Dosage & Application
Follow these guidelines for maximum, residue-free performance.
| Application Method | Dosage / Acre | Dosage / Hectare | Frequency |
|---|---|---|---|
| Soil Application | 2.0 kg | 5.0 kg | At planting or basal application per crop cycle |
| Seed Treatment | 10 g/kg seed | 10 g/kg seed | Once, before sowing |
Pro Tip: Use PHOSFIX alongside Phosora to maximize phosphorus availability — one unlocks existing soil phosphorus, the other supplies fresh slow-release phosphorus.
Compatibility Guide
What to Mix & What to Avoid
Understand compatibility protocols for safe and effective use in every application.
Mix Compatible
All certified organic inputs, bio-fertilizers, compost, and other AgroNext biological products.
Use with Caution
Can be integrated with conventional NPK programs to reduce synthetic fertilizer dependency over time. Avoid mixing concentrated chemical solutions directly in the tank.
Avoid
Strong chemical bactericides or fungicides in the same tank mix — maintain a 4–5 day buffer window before or after use.
Safety Reminder
Always follow label instructions. Wear appropriate protective equipment during mixing and application. Keep out of reach of children and store in a cool, dry place away from direct sunlight.
