Here's a breakdown of the key differences between farmyard manure and compost manure:
Farmyard Manure
* Source: Fresh animal waste, typically from cattle, horses, pigs, or chickens.
* Composition: Undigested plant material, animal feces, bedding (straw, sawdust, etc.), and urine. Contains higher amounts of nitrogen and phosphorus.
* Stage of Decomposition: Raw and partially decomposed. May contain weed seeds and pathogens.
* Characteristics: Strong odor, uneven consistency, can be hot (release heat as it decomposes).
* Uses: Directly applied to soil as a fertilizer, for soil amendment, and as a mulch.
* Time to Use: Needs to be aged for at least 6 months to a year before applying directly to plants to reduce the risk of burning.
Compost Manure
* Source: Farmyard manure that has been decomposed through controlled composting.
* Composition: Decomposed organic matter, including plant material, animal waste, and bedding. Has a more balanced nutrient profile (N, P, K) than raw manure.
* Stage of Decomposition: Fully decomposed, stable, and pathogen-free.
* Characteristics: Earthy scent, crumbly texture, nutrient-rich.
* Uses: Excellent fertilizer and soil amendment, can be applied directly to plants without burning risk.
* Time to Use: Ready to use immediately after composting.
Here's a table summarizing the main differences:
| Feature | Farmyard Manure | Compost Manure |
|-------------------|-------------------|-----------------------|
| Source | Fresh Animal Waste | Decomposed Farmyard Manure |
| Decomposition | Partially Decomposed | Fully Decomposed |
| Nutrients | High N and P | Balanced NPK |
| Odor | Strong, Ammonia-like | Earthy, Pleasant |
| Consistency | Uneven, Clumpy | Crumbly, Uniform |
| Weed Seeds/Pathogens | May contain | Mostly free of |
| Time to Use | 6 months - 1 year | Immediately |
In Summary:
* Farmyard manure: Requires aging to reduce its "hotness" and potential for harming plants.
* Compost manure: A safer and more readily available option for gardeners, providing beneficial nutrients to the soil.
Remember, both types of manure can greatly benefit your garden, but understanding their differences helps you use them effectively.
