Organic Manure Compost
What Is Organic Manure Compost?
Organic manure compost is a nutrient-dense natural fertilizer derived from decomposed animal waste and plant materials. It plays a critical role in improving soil structure, enhancing fertility, and promoting sustainable gardening practices. Unlike synthetic fertilizers is free of harmful chemicals and contributes to long-term soil health.
How Organic Manure Compost Works
Through the natural process of decomposition, microorganisms break down organic materials in the presence of oxygen. The result is a stable, humus-rich substance that enhances soil fertility, water retention, and microbial life. This compost is particularly useful in climates across the USA, from the arid Southwest to the humid Southeast.
Components of Organic Manure Compost
Animal Waste
- Cow dung: High in organic matter and microbes
- Poultry manure: Nitrogen-rich, fast-acting fertilizer
- Horse manure: Readily available, best when aged
- Sheep and goat manure: Low moisture, great for dry composting
Plant-Based Inputs
- Green waste: Grass clippings, kitchen scraps, vegetable peels
- Brown waste: Leaves, straw, cardboard, shredded paper
- Carbon sources: Essential for maintaining a healthy carbon-to-nitrogen ratio
Microbial Action Organic Manure Compost
The presence of beneficial microbes is crucial. These organisms facilitate the breakdown of materials, convert nutrients into plant-available forms, and outcompete harmful pathogens.
Benefits of Using Organic Manure Compost
Soil Improvement
Organic manure compost improves soil texture, enabling better root penetration and water retention. It transforms compacted, clay-heavy soil into loose, friable earth ideal for plant growth.
Nutrient Supply
Compost contains essential macro and micronutrients including nitrogen (N), phosphorus (P), potassium (K), calcium, magnesium, and sulfur. These nutrients are released slowly, ensuring long-term nourishment for plants.
Environmental Sustainability
Using compost helps reduce landfill waste, lower greenhouse gas emissions, and sequester carbon in the soil. Composting organic waste at home also minimizes municipal waste management costs.
Economic Benefits Organic Manure Compost
By creating compost at home or purchasing it locally, gardeners reduce dependency on expensive chemical fertilizers. Over time, healthier soil requires fewer amendments, saving money.
Types of Organic Manure Compost
Hot Composting
Hot composting involves maintaining high temperatures (130–160°F) within the pile to accelerate decomposition and kill pathogens. This method requires frequent turning and moisture monitoring.
Cold Composting
Cold composting is slower but less labor-intensive. Materials are added gradually, and the pile is turned occasionally. It may take six months to a year to mature.
Vermicomposting
This process uses earthworms to break down organic matter. Red wigglers (Eisenia fetida) are the most common species used. Vermicompost is nutrient-rich and excellent for container gardening.
Anaerobic Composting
Anaerobic composting occurs in the absence of oxygen. It produces compost more slowly and may release odors, but it is useful for enclosed systems like Bokashi composting.
How to Make Organic Manure Compost at Home
Step 1: Choose a Location
Select a shaded, well-drained area for your compost pile or bin. Avoid placing it directly on concrete or other impermeable surfaces.
Step 2: Gather Materials
Combine green materials (vegetable scraps, fresh grass) with brown materials (dry leaves, cardboard). Add animal manure in moderation.
Step 3: Layer the Pile
Alternate layers of greens and browns, adding a thin layer of soil or finished compost to introduce microbes. Keep the pile moist but not soggy.
Step 4: Turn Regularly
Aerate the pile weekly using a pitchfork or compost turner to introduce oxygen and speed up decomposition.
Step 5: Monitor and Maintain Organic Manure Compost
Check moisture levels and internal temperature. If the pile is too dry, add water; if too wet, add dry browns.
Step 6: Harvest the Compost
When the compost is dark, crumbly, and earthy-smelling, it’s ready to use. This typically takes 2–6 months depending on the method.
Best Practices for Using Organic Manure Compost
Pre-Planting Soil Amendment
Mix 1–2 inches of compost into the top 6–8 inches of soil before planting. This enriches the soil and prepares it for healthy root growth.
Top-Dressing and Side-Dressing
Apply compost around the base of established plants to provide slow-release nutrients throughout the growing season.
Lawn Applications Organic Manure Compost
Spread a thin layer of compost over lawns in spring and fall to improve soil structure, encourage root development, and reduce thatch.
Container Gardening
Mix compost into potting soil at a ratio of 1:3 for container-grown herbs, vegetables, and flowers.
Compost Tea
Steep compost in water for 24–48 hours to create compost tea, which can be sprayed on foliage or used as a soil drench to deliver nutrients quickly.
Organic Manure Compost vs Chemical Fertilizers
Nutrient Release
- Compost: Slow and steady
- Fertilizers: Fast-acting but short-lived
Soil Health
- Compost: Builds organic matter and microbial life
- Fertilizers: Can degrade soil structure and kill beneficial organisms
Environmental Impact Organic Manure Compost
- Compost: Reduces pollution, sequesters carbon
- Fertilizers: Risk of runoff and water contamination
Cost and Accessibility
- Compost: Low-cost or free if homemade
- Fertilizers: Recurring cost and potential overuse

Organic Manure Compost in Different U.S. Climates
Hot, Arid Regions
Add more green material and water regularly to maintain moisture.
Cold, Northern States
Insulate the pile during winter or use an enclosed bin to retain heat.
Humid Climates
Increase browns and turn more often to prevent sogginess and odors.
Legal Considerations and Safety Tips
Composting Regulations
Check local ordinances and HOA guidelines regarding compost pile size, location, and animal manure use.
Safety with Pathogens
Ensure temperatures reach 130°F to kill pathogens. Avoid using pet waste or manure from medicated animals.
Storage and Handling
Wear gloves, wash hands, and store compost tools away from edibles.
