Dairy farming provides income from milk, calves and breeding animals, but many farmers overlook another valuable resource found on the farm: dairy manure. What is often treated as waste can become an additional source of income when it is properly collected, processed and marketed.
With rising costs of fertilizer and livestock feed, farmers are increasingly looking for ways to get more value from every part of their farm. Dairy manure can be converted into organic fertilizer, compost, biogas and other useful products. Instead of allowing manure to accumulate around the cattle shed, farmers can turn it into a resource that supports both crop production and household income.
Selling dairy manure as organic fertilizer
One of the simplest ways to make money from dairy manure is to sell it as organic fertilizer. Well-managed cattle manure contains nutrients and organic matter that can improve soil fertility and structure.
Farmers growing vegetables, fruits, maize and other crops can use manure to improve their soils. Dairy manure can also be attractive to gardeners and small-scale farmers who want to reduce their dependence on synthetic fertilizers.
Instead of selling fresh manure immediately, farmers can allow it to decompose properly before marketing it. Properly managed manure is easier to handle and can be more appealing to buyers.
The manure can be bagged and sold in convenient quantities to nearby farmers, gardeners and agricultural enterprises. Farmers should ensure the product is handled hygienically and avoid making unsupported claims about its nutrient content.
Making and selling compost
Composting can increase the value of dairy manure. Rather than selling raw manure at a low price, farmers can combine it with suitable plant materials such as crop residues and allow the mixture to decompose under controlled conditions.
Good compost should be properly decomposed before it is used or sold. The process reduces the volume of organic material, creates a more uniform product and can make transportation and application easier.
Farmers with sufficient quantities of manure can produce compost for their own farms and sell the surplus. Packaging compost in manageable bags can also make it easier to reach urban gardeners, nurseries and small-scale vegetable growers.
The quality of the finished compost matters. Farmers should avoid selling material that is still undergoing active decomposition because immature compost can create problems when applied directly to crops.
Producing biogas from dairy manure
For farmers with several cattle and a consistent supply of manure, biogas production can provide both savings and income opportunities.
A biogas digester uses manure to produce methane-rich gas that can be used for cooking and, with suitable equipment, other energy applications. This can reduce the amount of money a household spends on conventional cooking fuels.
The process also produces a nutrient-rich digestate that can be used as a soil amendment or fertilizer when properly managed.
Although installing a biogas system requires an initial investment, the long-term benefits can make it worthwhile for farms with adequate manure supplies. Farmers should work with qualified installers to select a system that matches the number of animals and the amount of manure available.
Using manure to grow high-value crops
Farmers do not always need to sell manure directly to make money from it. One of the most profitable uses can be applying it to crops that generate higher returns.
Well-managed manure can improve soil organic matter and contribute nutrients to crops. Farmers can therefore use dairy manure to reduce fertilizer expenses while producing vegetables, fruits, fodder or other marketable crops.
For example, a dairy farmer can establish a vegetable garden near the homestead and use properly managed manure to improve soil fertility. The vegetables can then be sold locally, creating an additional income stream from the dairy enterprise.
This approach turns manure from a waste product into an input for another farm business.
Selling manure to vegetable and fruit growers
Farmers who keep dairy cattle in areas surrounded by horticultural farms may find a ready market for manure. Vegetable and fruit growers often need organic matter to improve their soils.
Instead of waiting for buyers to arrive at the farm, dairy farmers can identify potential customers in nearby farming communities. Local vegetable growers, nurseries, landscapers and home gardeners may all provide potential markets.
Transportation can become a major cost, particularly when manure is bulky. Selling to customers within a reasonable distance or organizing transport efficiently can help improve profitability.
Making manure briquettes
In some settings, organic waste can be processed into fuel briquettes. Dairy manure may be incorporated into briquette production alongside other suitable biomass materials.
However, this requires appropriate processing, drying and equipment, and farmers should understand the local market before investing. Briquettes must also be produced safely and in accordance with applicable environmental and health requirements.
For an individual dairy farmer, this may be more suitable as a group enterprise or small processing business rather than a standalone farm activity.
Improving manure management on the farm
Making money from dairy manure begins with proper collection and storage. Manure should not simply be left exposed in an open heap where nutrients can be lost through runoff and other processes.
A designated manure storage area can make collection easier and help farmers manage the material more effectively. Where possible, manure should be protected from excessive rainfall and runoff.
Farmers should also avoid allowing manure to contaminate water sources. Good manure management protects the environment while creating an opportunity to generate additional farm income.
Keep records to know whether manure is profitable
Like any other farm enterprise, manure businesses should be based on proper calculations. Farmers should record expenses such as labour, bags, equipment, transport, processing and marketing.
This helps determine whether selling raw manure, composting it, using it for crop production or investing in biogas provides the best return.
For some farmers, using manure on their own crops may create greater savings than selling it. For others, processing and selling compost may offer better returns. The best option depends on the farm’s location, manure volume, available labour and access to markets.
Dairy manure should not be viewed simply as waste. With proper management, it can become a valuable farm resource and an additional source of income.
Farmers can make money from dairy manure by selling it as organic fertilizer, producing compost, investing in biogas, supplying nearby crop growers or using it to produce high-value crops. The right approach depends on the amount of manure available and the demand in the local market.
For dairy farmers looking to increase profitability, manure offers an opportunity to reduce input costs while creating another income stream. Instead of allowing valuable nutrients to go to waste, farmers can turn what comes out of the cowshed into something that adds value to the entire farm business.
