Del McGill of Organix in Walla Walla, WA describes how farms use a flush system to wash cow manure out of the dairy alleys. The manure is then taken up to the separator where the water and solids are separated. The product that results is a high-quality landscaping fertilizer that's picked up by a semi-truck and transported to one of the hundreds of landscaping customers throughout the Northwest. These landscape supply businesses love the dairy compost fertilizer because it's easy to spread, and consumers can use it for their gardens, raised beds, and lawns.
