The Fertilizing Power of Horse Manure: Discover Its Benefits for Composting

Is Horse Manure Good for Compost?

In recent years, there has been a growing interest in sustainable gardening practices and organic fertilizers. One such fertilizer that has gained popularity is horse manure. But is horse manure really good for compost? Let’s dive into the topic and uncover the truth behind this natural soil amendment.

The Benefits of Horse Manure

Horse manure contains an abundance of nutrients that are beneficial to plants. It is rich in nitrogen, phosphorus, and potassium – commonly known as NPK – which are essential elements required for healthy plant growth. Additionally, it also contains smaller amounts of micronutrients like calcium and magnesium.

This nutrient-rich composition makes horse manure an excellent choice for improving soil fertility and structure. The presence of organic matter in the form of partially decomposed bedding materials adds humus to the soil, enhancing its water-holding capacity while promoting better drainage.

Composting Horse Manure

Step 1: Collecting Waste

The first step in using horse manure as compost is collecting the waste material from stables or paddocks. Ensure you gather both feces and soiled bedding materials like straw or wood shavings.

Step 2: Creating a Compost Pile

To start your compost pile, choose a suitable location away from sensitive areas like wells or water sources. Begin by layering equal parts green (nitrogen-rich) material such as fresh manure with brown (carbon-rich) material like dried leaves or hay.

Step 3: Managing Moisture Levels

Adequate moisture plays a crucial role in composting success. Aim for a moisture level similar to a well-wrung sponge. Regularly monitor and adjust the moisture content by adding water or dry materials as necessary.

Step 4: Turning the Pile

To speed up decomposition, occasionally turn the compost pile using a garden fork or shovel. This mixing process helps incorporate oxygen, which aids microbial activity and ensures efficient breakdown of organic matter.

Using Horse Manure Compost

Garden Beds and Vegetable Gardens

Horse manure compost can be used in garden beds or vegetable gardens as an organic fertilizer. Prior to planting, mix it into the top few inches of soil to improve nutrient levels and soil structure.


An additional benefit of horse manure compost is its effectiveness as mulch. Apply a layer around plants and shrubs to retain moisture, suppress weeds, and slowly release nutrients over time.

Cautions when using Horse Manure Compost

While horse manure is generally safe for use in gardening practices, there are a few precautions to keep in mind:

  • Avoid applying fresh horse manure directly onto plants as it may contain weed seeds that can proliferate in your garden.
  • Allow adequate time for proper decomposition before using horse manure compost on delicate seedlings or young plants.
  • If horses have been treated with medications like dewormers or antibiotics, their waste should not be used until these substances fully break down – typically six months to one year later – to avoid any potential negative effects on plant growth.

In Conclusion

Horse manure can indeed be an excellent addition to your compost pile. Its nutrient-rich composition and ability to improve soil structure make it a valuable organic fertilizer for gardens and vegetable beds. By following the proper composting procedures and taking necessary precautions, you can harness the benefits of horse manure as a sustainable gardening aid.
