There are many reasons to compost your horses manure. To start with composted manure is a more productive fertilizer option. It releases its nutrients at a slower rate and this creates a more consistent supply of nutrients rather than a quick boost.

The more consistent release of nutrients allows your pasture plants to fully utilize the fertilizer improving plant growth. Compost also has the ability of balancing pH levels.

Composting is a good way of controlling weeds in your pasture. During the composting process heat is naturally produced, this heat is usually at a high enough temperature that weed seeds will be prevented from germinating. So when you spread the finished compost on your pasture the seeds won't sprout into new plants.

Just like the weed seeds, parasite eggs and larvae can be killed by the heat produced from composting. This is also true for fly eggs and larvae.

Well, composting is the answer! During the composting process micro organisms are breaking down the raw material. As they do this, these critters are creating black gold. The finished product is smaller in size and you will see a reduction in your pile of up to 50%. And for those of you who are faced with having the manure trucked away this can add up to a decent savings over the year. Composting is beneficial to the Environment

Since the finished compost releases its nutrients at a slower rate pasture plants have the time to absorb more of the nutrients. The result is less nitrates slipping past the roots and sinking down (leaching) into your ground water. Compost is also less water soluble, so when the composted manure becomes wet it's less likely to turn to mud and rum off your property into ditches, creeks, or rivers. (Excess nitrates in water are very harmful to your self and the environment)

The site of a well constructed composter is usually more visually pleasing than a large pile of manure.
