Agriculture is the backbone of India’s economy, and about 50–55% of the population depends on farming for their livelihood. For many farmers, crop success is directly linked to survival, as poor soil health or low productivity can impact income, food security, and overall well-being. In recent years, farmers have started realizing that excessive use of chemical fertilizers harms soil fertility, reduces crop quality, and increases long-term costs. As a result, there is a growing shift towards natural and toxin-free organic farming practices that focus on sustainability rather than short-term yield. Farmers are now looking for solutions that not only provide essential plant nutrients (NPK) but also improve soil health. One such solution is PROM (Phosphate Rich Organic Manure), an organic and biologically active source of phosphorus that supports root development and crop growth while enhancing soil fertility. Unlike chemical fertilizers like DAP, which offer quick but short-term results, PROM works naturally and sustainably. In this blog, we will understand what PROM fertilizer is, how it works, and why it is a better choice than DAP for organic farming. What is PROM Fertilizer? PROM (Phosphate Rich Organic Manure) is an organic fertilizer that supplies phosphorus to plants naturally and sustainably. It is made by combining organic materials such as compost, cow dung, and plant residues with rock phosphate and beneficial microorganisms. This mixture is then composted properly to create a nutrient-rich manure. Unlike chemical fertilizers, PROM does not just provide nutrients to plants. It also improves soil quality by increasing organic matter and encouraging the growth of beneficial microbes. In simple terms, PROM supports both plant growth and soil health at the same time. Composition of PROM Fertilizer India Component Percentage Range Phosphorus 8% – 10% Nitrogen 0.4% – 2.5% Organic Carbon 7.9% – 28% How PROM (Phosphate Rich Organic Manure) Fertilizer Works PROM works in a natural way. Instead of releasing nutrients instantly like chemical fertilizers, it slowly releases phosphorus into the soil over time. The microorganisms present in PROM help break down nutrients and convert them into forms that plants can easily absorb. This process reduces nutrient loss and ensures a steady supply of phosphorus to crops. Because of the slow-release mechanism, PROM improves soil fertility over time and creates a more balanced and healthy growing environment for plants. Benefits of PROM Fertilizer PROM (Phosphate-rich organic manure) fertilizer offers several long-term benefits for both soil and crops. The benefits of PROM fertilizer are as follows: It improves soil structure by adding organic matter, which helps the soil retain moisture and nutrients more effectively. Over time, this leads to better soil fertility and productivity. PROM enhances microbial activity in the soil. The presence of beneficial microorganisms helps in nutrient cycling and supports plant growth naturally. This creates a living soil ecosystem, which is essential for sustainable farming. PROM provides nutrients slowly and steadily, reduces the loss of essential nutrients and provides plants with continuous nourishment throughout their growth cycle. Since PROM is organic, it is environmentally friendly and reduces the need for chemical fertilizers. This makes it a cost-effective and sustainable option for farmers. What is DAP( Diammonium phosphate)? DAP (Diammonium phosphate) is a synthetic, completely water-soluble inorganic fertilizer for plants. DAP is popular because when a farmer applies DAP to the field, the nutrients dissolve instantly, giving the crops a quick, explosive boost of phosphorus and nitrogen. It is widely used in agriculture because it delivers immediately available Phosphorus and Nitrogen to plants. DAP is not permitted in certified organic systems. Composition of DAP Fertilizer (Di-Ammonium Phosphate) The composition of DAP consists of Phosphorus and Nitrogen in the following ratio: Component Percentage Phosphorus 46% Nitrogen 18% Advantages of PROM in Comparison to DAP for Organic Farming? 1. Suitable for Organic Farming PROM is made from natural materials and is allowed in organic farming, while DAP is a chemical fertilizer and not suitable for organic systems. 2. Slow and Steady Nutrient Release PROM releases phosphorus gradually, which helps plants absorb it better and reduces wastage. DAP releases nutrients quickly, but it can lead to loss and inefficiency. 3. Improves Soil Health PROM adds organic matter to the soil, improving its structure, fertility, and water-holding capacity, which DAP does not provide. 4. Supports Beneficial Soil Microbes PROM encourages the growth of useful microorganisms that help in nutrient absorption. DAP does not support soil biology. 5. Reduces Environmental Damage PROM lowers the risk of nutrient runoff and pollution, while DAP can contribute to water contamination if overused. 6. Provides Additional Nutrients PROM supplies small amounts of other nutrients and trace elements, whereas DAP mainly provides only nitrogen and phosphorus. PROM Vs DAP: Basic Difference Feature PROM DAP Type Organic fertilizer Chemical fertilizer Nutrient release Slow and steady Fast Soil health Improves Degrades over time Microbial activity Increases Reduces Environmental impact Eco-friendly Can harm soil & water Why Organic Farmers are Switching to PROM Fertilizer Farmers practicing natural and organic farming have the goal to produce food that is pure, healthy, and free from synthetic chemicals while leaving the earth better than we found it. PROM aligns perfectly with this philosophy. Field trials on various crops, including paddy, wheat, watermelons and green gram, have yielded fantastic results. Reason to choose PROM Fertilizer- Increases water retention Improves drainage Promotes beneficial microbial activity Improves soil health by increasing organic matter and microbial activity. Strong and deep root systems. Better resistance to diseases and dry weather conditions. High nutritional density in crops. Practical Tips for Using PROM in Organic Farming Test soil Phosphorus levels and soil pH before application; tailor rates based on soil test recommendations for available Phosphorus. Apply PROM as a broadcast pre-plant amendment into the root zone; combine with banding and microbial inoculants if early availability is needed. Use high-quality, certified organic feedstocks and low-Cd rock phosphate to meet certification and safety standards. Monitor crop response and soil Phosphorus over seasons; PROM builds soil fertility over time, so track cumulative benefits. Combine PROM with other organic fertility practices: cover crops, compost, crop rotations and mycorrhizal inoculation to maximize phosphorus uptake and soil health. Crops Suitable for PROM Fertilizer PROM (Phosphate–rich organic manure) fertilizer is suitable for a wide range of crops, especially those that require a steady supply of phosphorus for proper growth. It works well for cereals, pulses, oilseeds, fruits, and vegetables, where root development and flowering are important. According to product applications offered by Kama International Organic Pvt Ltd, organic fertilizers and crop-specific solutions are commonly used for crops like pulses and cumin, along with general crops that require balanced nutrition and soil improvement.
