Horse manure is a rich source of nutrients that can be transformed into organic fertilizer, benefiting both gardens and farms. By employing composting and granulation techniques, horse manure can be converted into a valuable resource that enhances soil health and plant growth. This article outlines what to do with horse manure to make organic fertilizer?
Composting: The Foundation of Organic Fertilizer
Composting is a natural process that involves the aerobic decomposition of organic matter by microorganisms. It is a cost-effective and environmentally friendly way to convert horse manure into fertilizer. Here’s how to compost horse manure effectively:
- Collection and Preparation: Begin by collecting horse manure along with its bedding materials like straw or sawdust. This mixture aids in creating the right carbon-to-nitrogen ratio, essential for efficient composting.
- Building the Pile: Construct a compost pile that is approximately 3 to 5 feet tall and wide. This size ensures optimal heat retention and adequate airflow, both crucial for microbial activity.
- Aeration: Regularly turn the compost pile to introduce oxygen and prevent anaerobic conditions, which can cause unpleasant odors. Aeration accelerates aerobic decomposition and maintains a healthy microbial environment.
- Moisture Control: Maintain consistent moisture levels by watering the pile as needed. It should feel like a damp sponge to promote microbial activity without becoming waterlogged.
- Temperature Monitoring: Use a compost thermometer to ensure the pile reaches temperatures between 130°F and 150°F (54°C to 66°C). These temperatures are necessary to eliminate pathogens and weed seeds.
- Curing: Allow the compost to cure for several months until it becomes dark, crumbly, and has an earthy smell. At this stage, it is safe to use as an organic fertilizer.
Granulation: Enhancing Usability and Storage
While composting produces loose, crumbly material, granulation turns composted manure into compact pellets or granules, making it easier to handle, store, and apply. Here’s an overview of the horse manure granulation process:
- Mixing and Drying: Begin by ensuring the compost is adequately dried to reduce moisture content. This can be achieved by further air-drying the material after composting.
- Grinding: Use a grinder to break down the compost into a fine powder. This step is crucial for creating uniform granules.
- Binding and Forming: Mix the powdered compost with a binding agent, such as lignin or bentonite clay, to help the particles stick together. The mixture is then fed into a granulator machine, which compresses it into small, dense pellets.
- Drying and Cooling: After granulation, the pellets are dried further to remove any remaining moisture and then cooled to ensure stability.
- Packaging and Storage: The final granulated product can be packaged and stored easily, maintaining its nutrient content over time and allowing for convenient application.

Benefits and Application
Both composted and granulated horse manure have numerous benefits when used as organic fertilizers. They improve soil structure, enhance moisture retention, and provide essential nutrients for plant growth. Granulated manure, in particular, offers ease of use and precise application rates, making it suitable for both small gardens and large agricultural fields.
In conclusion, transforming horse manure into organic fertilizer through composting and granulation is a sustainable practice that supports soil health and plant vitality. By following these processes, you not only recycle waste but also contribute to environmentally responsible farming and gardening practices.
