HILMAR – Two years into an experiment in dairy manure handling, the worms are proving their worth.
A $483,950 federal grant helped pay for a system where these creatures break down most of the nitrogen in water used to flush out dairy stalls. The partners aim to reduce the risk of water and air pollution.
As a bonus, the worms leave their own manure, known as castings, a pleasant-smelling fertilizer that can be sold to home gardeners and farmers.
