Cow dung fertilizer is cow manure that has been composted so it is safe for crops. It contains modest amounts of nitrogen, phosphorus and potassium, but its real value is organic matter: it makes soil looser, helps it hold water and feeds the soil life that keeps fields productive.
Farmers have used cow dung for thousands of years, and it is back in demand as growers look for ways to rebuild tired soil. It is not a replacement for mineral fertilizer on a high-yield crop, but used together, the two work better than either alone.
What is in cow dung fertilizer?
Composted cow manure typically contains:
| Nutrient | Typical content |
|---|---|
| Nitrogen (N) | 0.5 to 1.5% |
| Phosphorus (P) | 0.3 to 0.8% |
| Potassium (K) | 0.4 to 1.0% |
| Organic matter | High |
Because the nutrient levels are low, cow dung works mainly as a soil conditioner and slow-release nutrient source. For a crop’s peak needs, farmers combine it with mineral fertilizers such as urea or NPK.
Types of cow dung fertilizer
- Fresh manure: not for direct use. It can burn plants, smell strongly and carry weed seeds and pathogens.
- Composted cow manure: fully broken down, earthy-smelling and safe. The most common form.
- Dried or powdered cow dung: easier to store, pack and transport.
- Pellets: compact and easy to spread, popular for retail and gardens.
- Vermicompost: cow dung processed by earthworms into a fine, rich compost.
How it is made
- Fresh dung is collected from dairy or cattle farms.
- It is mixed with straw, crop residues or other organic waste.
- The pile is composted and turned regularly, usually for about two to four months, so heat kills weed seeds and pathogens.
- The compost is dried, screened to remove stones, and packed or pelletised.
Benefits for soil and crops
- Adds organic matter and improves soil structure
- Helps sandy soils hold water and heavy soils drain
- Feeds earthworms and beneficial microbes
- Releases nutrients slowly, with little risk of burning plants
- Helps mineral fertilizers work more efficiently
It suits field crops such as rice, wheat, maize and sugarcane, vegetables, fruit trees, gardens and lawns, and it is widely used in organic farming. Compare the two approaches in organic vs chemical fertilizers.
How much to apply
As a general guide for composted manure:
- Field crops: 2 to 5 tonnes per hectare, worked in before sowing
- Vegetables: 1 to 2 kg per planting pit
- Fruit trees: 5 to 10 kg around the root zone
- Gardens: mix about one part compost to four parts soil
- Lawns: a thin layer, then water it in
Apply it before planting, during land preparation or after harvest. Never use fresh manure close to harvest on food crops.
What drives the price
Prices vary widely. The main factors are:
- Processing level: raw, composted, dried, powdered, pelletised or vermicompost
- Moisture and nutrient content
- Packaging: bulk, big bags or small retail packs
- Freight: manure is bulky, so transport is a large share of the cost
- Certification: for example, approval for organic farming
Importing cow manure
Cow manure is an animal by-product, so many countries regulate its import. Expect requirements such as treatment or composting standards, phytosanitary or veterinary certificates and fumigation. Check the rules in your country before ordering.

Frequently asked questions
Is cow dung a good fertilizer?
Yes, for building soil health. It adds organic matter and nutrients slowly. For high yields, it is usually combined with mineral fertilizers.
What is the NPK of cow dung fertilizer?
Composted cow manure typically contains about 0.5 to 1.5% nitrogen, 0.3 to 0.8% phosphorus and 0.4 to 1.0% potassium.
Can I use fresh cow dung on plants?
No. Fresh manure can burn plants and carry pathogens and weed seeds. Compost it first.
How long does cow dung take to compost?
Usually about two to four months, with regular turning.
How much cow dung should I use per hectare?
About 2 to 5 tonnes of composted manure per hectare for field crops, worked in before sowing.
Can cow dung replace chemical fertilizers?
Not fully on high-yield crops, because its nutrient content is low. It works best alongside mineral fertilizers.
