Introduction:
Phosphate Rich Organic Manure (PROM) is a sustainable, eco-friendly fertilizer that delivers a
slow-release source of phosphorus, crucial for healthy root development and overall plant growth.
It is produced by enriching low-grade rock phosphate with organic materials such as
cow dung, compost, or vermicompost.
PROM typically contains:
• 10–16% citrate-soluble phosphorus (P₂O₅)
• 10–20% organic carbon
• Trace amounts of nitrogen and potassium
Unlike chemical alternatives like DAP, PROM nourishes the soil without degrading its health.
It improves microbial activity, enhances humus formation, increases water retention,
and effectively corrects phosphorus deficiencies in a natural, balanced way.
Relevance and Future Potential:
With growing concerns over soil degradation, chemical overuse, and food safety, PROM is
gaining traction as a vital input in organic and sustainable agriculture. Governments and
agricultural bodies worldwide are actively promoting its use through:
• Subsidies and training programs
• Research on bio-enriched variants
• Promotion of export to residue-conscious markets
PROM can also be fortified with phosphate-solubilizing bacteria and other
beneficial microbes to further enhance its efficiency and environmental value.
As the agricultural sector transitions toward regenerative, climate-resilient
practices, PROM is poised to become a key component in restoring soil health,
improving productivity, and ensuring food security in a sustainable way.
Nutrient Composition of PROM
Nutrient Typical Range Remarks
Available Phosphorus (P₂O₅) 10% – 16% ( citrate soluble ) Primary nutrient for root development and growth
Organic Carbon 10% – 20% Enhances soil structure and microbial activity
Nitrogen (N) 0.4% – 1% Supports leaf growth and overall plant vigor
Potassium (K₂O) 0.4% – 1% Aids flowering, fruiting, and disease resistance
Moisture Content 15% – 25% Ensures microbial viability and product stability
Beneficial Microbes Varies (based on enrichment) Improves nutrient solubilization and soil health
Importance & Benefits of PROM (Phosphate Rich Organic Manure)
Enhances Soil Fertility
Releases phosphorus gradually, promoting sustained nutrient availability and increasing microbial activity in the soil for long-term fertility.
Eco-Friendly Alternative to DAP
Unlike chemical fertilizers like DAP, PROM does not disrupt soil pH or cause salt build-up, preserving soil health and structure.
Boosts Root Development
Encourages early seedling establishment and supports the formation of strong, deep root systems for improved nutrient and water uptake.
Increases Organic Matter
Improves humus content and enhances the soil’s water-holding capacity, aiding in drought resilience and better plant growth.
Supports Sustainable Agriculture
PROM is approved for organic farming and aligns with eco-friendly and regenerative agriculture practices, making it ideal for residue-free farming.
Cost-Effective & Resource-Efficient
Utilizes locally available organic waste, helping farmers reduce dependency on costly chemical fertilizers while promoting circular farming.
