Understanding Phosphate Rich Organic Manure (PROM)
A Complete Guide to Organic Phosphorus Nutrition for Healthier Plant Growth

What Is Phosphate Rich Organic Manure (PROM)?

Phosphate Rich Organic Manure (PROM) is a naturally produced, eco-friendly phosphorus fertilizer that offers a sustainable alternative to chemical phosphates like DAP (Diammonium Phosphate). It's created by co-composting organic matter—such as farm waste, crop residues, and manure—with high-grade rock phosphate, resulting in a nutrient-rich organic manure that enhances soil fertility and promotes healthy crop growth.

PROM isn't just a fertilizer; it's a soil rejuvenator that combines the benefits of organic carbon with readily available phosphorus, making it ideal for both organic and conventional farming systems.

What Makes PROM Special? Key Nutrient Profile

ComponentContentBenefit
Phosphorus (P₂O₅)8–12%Essential for root & flower development 
Organic Carbon8–10%Improves soil health & microbial activity 
Nitrogen0.4%+Supports balanced plant nutrition 
C/N Ratio20:1Ensures slow, steady nutrient release 
Nutrient AvailabilityUp to 10 monthsLong-term feeding for crops 

7 Powerful Benefits of Using PROM

1. Superior Root & Flower Development

PROM stimulates robust root growth, resulting in stronger, more productive crops with better flowering and seed formation.

2. Reduces Chemical Fertilizer Dependency

Research shows PROM can completely replace phosphatic fertilizers like DAP, reducing costs and chemical dependency.

3. Enhances Soil Microbial Activity

The organic carbon in PROM boosts soil biodiversity, increasing microflora and promoting healthier rhizosphere conditions.

4. Slow-Release Nutrient System

Unlike chemical fertilizers that release nutrients rapidly, PROM provides slow-release nutrients, ensuring long-term availability to plants.

5. Improves Disease Resistance

Crops grown with PROM show better resistance against diseases, reducing the need for chemical treatments.

6. Better Soil Structure & Water Retention

PROM increases moisture retention and improves soil structure, making it more resilient to drought conditions.

7. Economically Advantageous

Field trials show PROM-treated plots generate ₹320–₹1,850 additional income per hectare over control plots. It's also cheaper than chemical fertilizers.

Which Crops Thrive with PROM?

PROM is ideal for all crops, including:

  • Field Crops: Paddy, wheat, maize, cotton, sugarcane
  • Vegetables: Tomato, potato, brinjal, onion, capsicum
  • Fruits: Mango, banana, citrus, grapes, pomegranate
  • Plantations: Tea, coffee, rubber, coconut
  • Horticulture & Floriculture: Lawns, gardens, nurseries
  • Sericulture: Suitable for silk farming systems

How to Apply PROM

Application Rates

  • Tree crops (coconut, mango): 2–5 kg per tree
  • Field crops: Use as basal application before planting
  • Gardening: Suitable for rooftop vegetables, herbs, flowering plants

Best Practices

  • Apply as basal dose (before planting) for maximum effectiveness
  • Mix well with soil for better nutrient distribution
  • Continuous application increases organic carbon levels in soil over time

PROM vs. Chemical Fertilizers: The Clear Winner

FactorPROMChemical (DAP/SSP)
Nutrient ReleaseSlow, steady (10 months)Rapid, short-term
Soil HealthImproves structure & microfloraDegrades over time
Environmental ImpactEco-friendly, green chemistryPollution risk
CostCheaper Expensive + subsidy burden
Multi-crop EffectivenessWorks for 2nd crop too One-season effect
Disease ResistanceIncreases No benefit

Research indicates PROM is more efficient at adding phosphorus to soil than chemical fertilizers.

The Science Behind PROM Production

PROM is produced through bioconversion technology using:

  • Phosphate rock ore
  • Organic manure (vermicompost or biogas sludge)
  • Microbial culture (Bacillus megatherium var. phosphaticum)

This process converts phosphate rock into soluble phosphates directly assimilable by plants. The technology is cost-effective and can be integrated with biogas generation systems for extra profitability.

Why PROM Matters for Sustainable Farming in India

For farmers in Telangana and across India, PROM offers:

  • ✅ Reduced subsidy burden and foreign currency savings
  • ✅ Better yields compared to 100% NPK control
  • ✅ Long-term soil fertility for successive crops
  • ✅ Alignment with organic farming trends
  • ✅ Eco-friendly practice supporting responsible agriculture

Final Thoughts: Your Next Step Toward Better Farming

Phosphate Rich Organic Manure isn't just another fertilizer—it's a complete soil health solution that delivers phosphorus while rejuvenating your land. With phosphorus availability lasting up to 10 months, reduced chemical costs, and improved crop quality, PROM represents the future of smart, sustainable farming.
