Microbax Microphos PSB is a specialised biofertilizer marketed by Way2Agritech, designed to maximise phosphorus availability in the soil for better crop growth and yield. Microphos PSB works by converting insoluble phosphates into forms that plants can easily absorb, ensuring a steady supply of phosphorus throughout the crop cycle. This plays an important role in improving root development, energy transfer, and overall plant performance. Microphos PSB actively works in the root zone by releasing organic acids that help unlock fixed phosphorus in the soil. Microphos PSB supports crop establishment and enhances flowering and fruiting. By improving nutrient uptake and beneficial microbial activity, it reduces dependence on bulk chemical fertilizers long-term sustainable farming.

Stage Specific Benefits
- •Early Root Development Stage: Activates phosphate-solubilizing microbes, enhances root growth, and improves early phosphorus availability for strong crop establishment.
- •Vegetative Growth Stage: Supports energy transfer within plants, promotes healthy leaf development, and improves overall plant vigor.
- •Flowering & Fruiting Stage: Enhances phosphorus mobilization, supports better flowering, and improves fruit/grain formation and development.
- •Soil Fertility Enhancement: Enriches beneficial microbial population, improves phosphorus cycling, and boosts long-term soil productivity and sustainability.

Dosage & Method of Application
- 1.Soil Application: Apply 1–3 kg per acre based on soil fertility and crop requirement.
- 2.Drip Application (Fertigation): Dilute in water and apply through drip irrigation system for better root absorption.
- 3.Frequency of Application: Apply at time of sowing and 1-2 times per crop along with other suitable nutrient products.
Crop-Product Advisory
- 1.Soil Condition Dependency: Best for phosphorus-deficient, alkaline, and fixed-phosphorus soils to improve P availability and root growth.
- 2.Antagonism: Avoid mixing with chemical fungicides. Choose the right mix of products with Microphos PSB based on soil analysis for better field performance.
- 3.Recommended Combination: Apply with Bio-N + Zinc for better root development, flowering, and nutrient uptake.
- 4.Application Interval: Apply mainly during early growth and root establishment stages.
- 5.Precaution: Apply in moist soil near root zone; avoid chlorinated water and dry soil for better microbial activity.
