PROM (Phosphate‑Rich Organic Manure)

Closing the Loop with phosphate rich organic manure

Mineral P is finite, prices yo‑yo and soils lose carbon. Our PROM brings circularity: Rock‑phosphate reacts with digester cake to form slow‑release P₂O₅ bound to humic carbon. The granular organic fertilizer carries beneficial Bacillus and Trichoderma that rebuild micro‑flora, making it the flagship input for sustainable farming movements. Farmers using PROM qualify for subsidies under biofertilizer in India schemes while commanding a premium in certified produce markets hungry for organic manure‑grown crops.

Production Protocol

  • Screw‑press dewatering to 35 % solids.
  • Phosphate enrichment at a 6 : 1 cake‑to‑rock ratio.
  • Thermophilic curing (55 °C, 7 days) kills pathogens.
  • Roller granulation into 4 mm prills; output 80 t/day

Field Performance Snapshot

  • Crop | PROM (t/ha) | Control (DAP) | Yield Gain
  • Sugarcane | 2.0 | 0.0 | +11 %
  • Soybean | 1.0 | 60 kg P₂O₅ | +8 %
  • Turmeric | 1.5 | 40 kg P₂O₅ | +9 %

Value to Farmers

  • A 2 ha sugarcane block replacing DAP with PROM saved ₹8,000 in fertilizer and earned ₹42,000 extra from higher cane weight—net gain ₹34,000.
