How to Make Fertilizer from Cow Dung: A Complete Guide

Cow dung fertilizer is an organic fertilizer that is rich in nutrients and promotes soil health. It is a sustainable and eco-friendly alternative to synthetic fertilizers that can harm the environment. Making fertilizer from cow dung is easy and cost-effective, and can be done at home with minimal equipment. In this article, we will provide a complete guide on how to make fertilizer from cow dung, including how to make manure from cow dung, how to make organic fertilizer from cow dung, and how to make bio fertilizer from cow dung.


Cows are widely used domesticated animals that produce billions of pounds of dung daily. Reduce the length of the following sentences.

Nutrients in Cow Dung

Cow manure contains 14.5% organic matter, 0.30-0.45% nitrogen, 0.15-0.25% phosphorus and 0.10-0.15% potassium.

Organic matter and nutrient content in a variety of livestock is low, fine texture, more water, slow decomposition, low calorific value, is a late-acting fertilizer.

Cow manure is a cold fertilizer due to its high water content and poor ventilation, and organic matter is difficult to decompose. Dry fresh manure and add horse manure to mix and accumulate, and loose and high-quality organic fertilizer can be obtained.

Benefits of Cow Dung as Fertilizer


Cow dung contains valuable nutrients such as nitrogen, phosphorus, and potassium that are essential for plant growth. It has been used as a fertilizer for centuries due to its rich organic matter content. Cow dung-based fertilizers provide numerous benefits, such as improving soil structure, texture, and water-holding capacity. They also increase the soil’s microbial activity, making it easier for roots to penetrate and access nutrients.

Cow dung-based fertilizers are organic, cost-effective, and eco-friendly, as they do not contain any synthetic chemicals or additives. This makes them a sustainable option for farming and gardening, promoting the use of natural resources and reducing waste. Using cow dung as fertilizer helps to reduce dependence on synthetic fertilizers, which can have negative environmental impacts.

Types of Cow Dung Fertilizers

  • To make cow dung-based fertilizers, you can choose from several types depending on your specific needs and the availability of resources. Some of the most common types are:
  • Cow Dung Manure: This fertilizer is the most basic type and involves collecting fresh cow dung and allowing it to decompose naturally over time. The process can take anywhere from three to six months, depending on the climate and other environmental factors.
  • Organic Fertilizer: You can make this type of fertilizer by mixing fresh cow dung with other organic materials such as compost, green manure, or bone meal. Then, the mixture decomposes and matures over time, producing a nutrient-rich fertilizer that can benefit a wide range of plants.
  • Vermicompost: To make this type of organic fertilizer, you can feed cow dung to earthworms. The earthworms break down the cow dung and other organic materials, producing a nutrient-rich compost that is high in beneficial microorganisms.
  • Biogas Slurry: This type of liquid fertilizer is produced during the process of generating biogas from cow dung. It is a rich source of nutrients such as nitrogen, phosphorus, and potassium and can be used as a foliar spray or added directly to the soil.

How to Make Cow Dung Fertilizer

  1. Collecting cow dung – The first step in making fertilizer from cow dung is to collect the cow manure from the farm or dairy. It’s important to collect the cow dung regularly and keep it in a dry place to prevent the growth of harmful bacteria.
  2. Dewatering – The collected cow dung usually contains a lot of water, which can hinder the composting process. You can use the cow dung dewatering machine to separate the solid and liquid components of cow dung.This will make the cow manure more suitable for composting and help reduce the composting time.
  3. Composting – Composting is the process of breaking down the organic matter in the cow dung using microorganisms such as bacteria and fungi. A composting machine can be used to create a controlled environment that promotes the growth of these microorganisms. The composting process takes a few weeks to a few months depending on the size of the compost pile and the conditions.
  4. Granulation – After the composting process is complete, the compost needs to be granulated. A fertilizer granulator can be used to create granules of the compost. The granules are easier to store, transport and apply to crops.
  5. Drying the granulated fertilizer requires the removal of excess moisture before storage or packaging. One can use a drying machine to remove moisture from the fertilizer granules.
  6. After drying the fertilizer granules, they may become too hot to handle. Therefore, a cooling machine is necessary to cool them down to room temperature.
  7. Packaging – The final step is to package the fertilizer granules in bags or containers for sale or distribution.
