Phosphorus Solubilizing Bacteria (Bacillus megaterium var. phosphaticum)
Biofertilizer that releases phosphorus already trapped in the soil by earlier fertilizer applications, cutting the need for additional phosphatic fertilizer while improving soil quality.
A quick look at the key details that make Phosfix the right choice for your farm.

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

See exactly how Phosfix targets pests in 3 simple steps.
Bacillus megaterium var. phosphaticum secretes organic acids such as succinic acid in the rhizosphere.
These acids dissolve fixed, insoluble phosphorus compounds accumulated from earlier fertilizer use.
Solubilized phosphorus becomes accessible for direct root uptake, supporting flowering and fruiting.

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.
Understand compatibility protocols for safe and effective use in every application.
All certified organic inputs, bio-fertilizers, compost, and other AgroNext biological products.
Can be integrated with conventional NPK programs to reduce synthetic fertilizer dependency over time. Avoid mixing concentrated chemical solutions directly in the tank.
Strong chemical bactericides or fungicides in the same tank mix — maintain a 4–5 day buffer window before or after use.
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.
