As gardeners, we’re always on the lookout for ways to enrich our soil and boost our plant health. One resource that is often overlooked is sheep manure. This natural byproduct is a treasure trove of nutrients and organic matter, which, when processed into granules, becomes an effective and easy-to-apply fertilizer. Let’s walk through the process of converting raw sheep manure into beneficial granules for your garden.
Why Sheep Manure?
Sheep manure is a cold manure, meaning it’s less likely to contain seeds or pathogens that can harm your plants. It is also packed with nutrients like nitrogen, phosphorus, and potassium, along with micronutrients that are essential for plant growth. Granulating sheep manure not only makes it easier to store and apply, but it also breaks down more slowly, providing a steady supply of nutrients to your plants.
Step 1: Collection and Pre-Processing
The journey from raw manure to granules starts with collection. Gather fresh manure from sheep pens or fields, ensuring that it’s free from debris like rocks or plastic. Fresh manure can be high in moisture, which isn’t ideal for granulation. Therefore, allow the manure to dry, either by spreading it thinly in a sunny area or using a manure dryer. Once dried, it should be ground into a fine powder. This can be done using a hammer mill or similar grinding equipment. In this, you can make sheep manure into better fertilizer pellets.
Step 2: Composting
Raw sheep manure can contain pathogens and weed seeds, which can be mitigated through composting. Composting not only destroys harmful organisms but also stabilizes the nutrients. Create compost piles by layering sheep manure with carbon-rich materials like straw or sawdust. Turn the piles regularly to aerate them and ensure even decomposition. This process usually takes a few months; But, you can short it by suitable sheep manure compost machines. You’ll know it’s ready when the material is dark, crumbly, and smells earthy.
Step 3: Mixing and Conditioning
Before granulation, the composted manure should be mixed with other soil amendments to balance the nutrient content according to your plants’ needs. Additives like bone meal or potash can be blended in at this stage. The mixture then needs to be conditioned for granulation. This involves achieving the correct moisture content (usually around 10-15%) to ensure the granules can form and hold their shape.
Step 4: Granulation
Now comes the core of the process: turning the prepared mixture into granules. There are several granulation methods, including extrusion, pan granulation, or a drum granulator. Each of these methods applies force to the mixture, causing it to compact into small, dense balls. The size of the granules can be controlled by adjusting the machine settings.

Step 5: Drying and Cooling
The newly formed granules will be high in moisture, which could lead to spoilage or mold growth. They need to be dried using a rotary dryer or a similar device. Once dried, the granules should be cooled to prevent caking. The cooling process can be done by spreading the granules out in a thin layer and allowing them to sit at room temperature.
Step 6: Screening and Packaging
After cooling, the granules should be passed through a rotary screener to separate the correctly sized granules from the dust and oversized particles. The right-sized granules are then ready for packaging. They can be bagged in plastic or paper bags and stored in a dry place until ready to use.
Applying Sheep Manure Granules to Your Garden
When it’s time to use your sheep manure granules, apply them to your garden beds or around your plants. Because they’re a slow-release fertilizer, they will provide nutrients over time, reducing the need for frequent applications. Be sure to follow general guidelines for manure-based fertilizers – apply them in the correct quantities and at the right time to prevent nutrient runoff and to maximize their effectiveness.
Transforming sheep manure into granules is an excellent way to create a sustainable, eco-friendly fertilizer for your garden. By following these steps, you’ll be able to harness the full potential of sheep manure, turning what might have been waste into a resource that enriches your soil, supports your plants, and contributes to a more circular gardening practice.
