To the hay industry, "Certified" simply means that a forage product is free of any noxious weeds. The correct terminology should always be "Certified Noxious Weed Free". Enforcement of the law is becoming quite prevalent in requiring "certified noxious weed free" forages when taking animals and animal feed onto Federal or State land ei. National Forest, State Forest, BLM land, etc. We keep a variety of hay and pellets that are "Certified Noxious Weed Free" throughout the year. Types of hay and inventory varies, give us a call.
