Phosphate Rich Organic Manure (PROM) is an eco-friendly fertilizer made by enriching organic manure with rock phosphate. It provides slow-release phosphorus, improves soil fertility, enhances root growth, and supports sustainable farming. Ideal for all crops as a natural alternative to chemical phosphatic fertilizers like DAP.
What is PROM Fertilizer?
Phosphate Rich Organic Manure (PROM) is a type of enriched organic fertilizer that serves as an alternative to chemical phosphatic fertilizers like DAP (Di-Ammonium Phosphate) and SSP (Single Super Phosphate). PROM is specially designed to provide phosphorus in a natural and eco-friendly form, enhancing soil fertility while maintaining long-term soil health.
๐ฑ Composition of PROM:
Organic Manure Base (such as compost, cow dung, or press mud)
Rock Phosphate (natural source of phosphorus)
Bio-enhancers like Phosphate Solubilizing Bacteria (PSB) โ optional
May also contain trace minerals, micronutrients, and beneficial microorganisms
๐งช Typical Nutrient Content:
Phosphorus (PโOโ
): 10% to 16% (depends on quality of rock phosphate)
Organic Carbon: 12% to 18%
Moisture Content: โค 25%
C/N Ratio: Within optimal range (20:1 to 30:1)

Key Benefits of PROM Fertilizer:
Improves Soil Fertility:
Supplies slow-release phosphorus
Improves organic matter content in soil
Eco-Friendly & Sustainable:
Reduces dependency on chemical fertilizers
Promotes organic farming
Enhances Root Growth:
Phosphorus is vital for root development and seedling strength
Improves Water Holding Capacity:
Organic content increases soil porosity and moisture retention
Cost-Effective:
Often cheaper than chemical alternatives like DAP or SSP
No Soil or Groundwater Pollution:
Organic components break down naturally without residue
๐งโ๐พ Recommended Uses:
Suitable for all crops: cereals, vegetables, fruits, pulses, oilseeds
Can be applied at basal dose during land preparation
Ideal for both rainfed and irrigated conditions
๐ Why PROM is Gaining Importance:
Promoted under sustainable and organic agriculture missions in India
Recognized by government bodies like FCO (Fertilizer Control Order)
Helps reduce chemical load in food chain and soil ecosystem
