Clackamas conservation district: Got manure? Put a cover on it!
If you have livestock or horses, then you have manure! You may have a mountain of manure that grows daily. So, is it a problem or is it a benefit?
If large piles of manure are open to the rain, it can be a problem. Water will soak through the pile and carry nutrients and bacteria away from the pile and into nearby streams or ditches. It can also soak into the ground and may pollute groundwater. You will also lose valuable nutrients that your pasture may need.
A simple solution is a tarp. Cover your manure pile with a heavy tarp and good weights to hold it down against strong winds. You will keep the beneficial nutrients and you will not be polluting streams or groundwater.
Tarps are temporary. What about a permanent solution? Consider a manure storage shed. This is a simple three-sided shed with a roof to keep the rain out. A shed is easier to manage than a tarp when doing daily chores.
Composting controls the breakdown of natural waste, such as plants, food or manure. When you compost manure, it reaches a temperature that kills weed seed and bacteria. It also improves the smell. What is produced? A nutrient-rich compost that can be spread on a pasture or used in fields or gardens to improve soil health is the result of composting manure.
Is composted manure better than "aged" manure? Yes! Manure that has been sitting around for a long time without composting is still smelly. It can also have weed seeds that will still grow and bacteria that can be harmful.
