Organic fertilizer manufacturing process in india

Organic farming is gaining popularity in India, and with it comes the need for organic fertilizers. Unlike chemical fertilizers, organic fertilizers are made from natural materials that provide plants with essential nutrients without causing harm to the environment or creating imbalances in the soil. In this article, we will discuss the organic fertilizer manufacturing process in India.

Source of raw materials

Organic fertilizers are made from natural materials, such as animal manure, crop residues, green manure, and compost. These materials can be obtained from farms, livestock farms, and vegetable markets. The raw materials need to be of good quality, free from pollutants, and properly decomposed.

Mixing of raw materials

The raw materials are mixed in a specific ratio to ensure the right balance of nutrients. For example, a typical mixture could include 40% cow dung, 10% bone meal, 10% rock phosphate, 10% neem cake, 20% green manure, and 10% compost. The mixing process can be done manually or by using a Fertilizer mixing machine.


After the raw materials are mixed, the mixture is placed in a composting pit or a composting machine. The composting process takes about 3-4 weeks, during which the mixture is turned regularly to ensure proper aeration. The temperature of the composting pile should be maintained between 50-60°C for efficient decomposition.


After the composting process is complete, the mixture is allowed to cure for another 2-3 weeks. Curing helps to stabilize the nutrients in the fertilizer and reduces the risk of pathogens and weed seeds.

Grinding and sieving

The cured mixture is then ground into a fine powder using a grinder. The powder is then sieved to remove any large particles or lumps.

Packaging and storage

The organic fertilizer is then packaged in bags or containers and stored in a cool and dry place. Proper storage helps to maintain the quality of the fertilizer and prevents moisture from affecting its nutrient content.

Quality control

Quality control is an important aspect of organic fertilizer manufacturing. The final product should be free from pathogens, weed seeds, and heavy metals. The nutrient content should also be within the desired range. Regular testing and analysis of the fertilizer can help to ensure its quality.

Marketing and distribution

Marketing and distribution of organic fertilizers can be done through various channels, such as agro-input stores, farmers’ cooperatives, and online platforms. Awareness campaigns and training programs can also be conducted to promote the use of organic fertilizers among farmers.

In conclusion, the organic fertilizer manufacturing process in india involves sourcing high-quality raw materials, mixing them in the right proportion, composting, curing, grinding, sieving, packaging, and quality control. Organic fertilizers offer a sustainable and eco-friendly alternative to chemical fertilizers, and their use can help to improve soil health, increase crop yields, and reduce environmental pollution. With the growing demand for organic products, the organic fertilizer industry in India has a bright future.
