Ivermectin worming medication can pass through horses and kill beneficial insects in the environment.
Certain herbicides are used on hay that "persist," and can cause your composted manure to kill plants that it is used on.
What can I do as a horse farm owner/manager to reduce the risk of persistent herbicides in my horses’ manure and manure compost?
