Manure Management

Livestock manure and bedding can be a valuable, reusable resource as a fertilizer or medium for making soil compost. It can be applied to gardens, crops, lawns and pastures. But because manure contains bacteria as well as nutrients, it must be managed correctly to avoid doing more harm than good. Good management means preventing runoff to soil and water from unmanaged piles of material.

In some cases, even the nutrients can be harmful. For example, runoff containing excess nitrogen can cause algal blooms on surface waters and rob the aquatic life below of valuable oxygen. But when managed properly, manure can be a nutrient-rich, beneficial soil amendment.

In 2000, an estimated 290,000 tons of horse manure and bedding material were generated in King County! Managed properly, this is nearly a third of a million tons of soil amendment than can be used as a fertilizer or compost medium.

Options for Managing Manure

  1. Use it on site (also see this manure mangement brochure (PDF, 500 K)).
  2. Give it away. The King Conservation District maintains a manure share list (external) to link people that have manure with those who want it.
  3. Haul it off site for composting.
  4. Haul it off site for disposal.

The first three options are the most environmentally friendly because they turn a potentially disposable product into a reusable resource. If at all possible, disposal should be a last choice.

King County's Livestock Management Ordinance calls for farms with livestock to either complete a farm plan or implement best management practices (BMPs) that protect the environment from the impacts of livestock.
