The venom of the black widow spider contains poisonous chemicals that make people sick. Black widows are found throughout the United States, mostly in the South and West. They are usually found in barns, sheds, stone walls, fences, woodpiles, porch furniture, and other outdoor structures.
Some types of grass hay, in dry weather conditions or on dry ground, will be much too dry when baled as small bales using the eight to 15 percent moisture (the traditional rule of thumb) as a guide. Some of this grass hay produces the best quality bales when baled at 24 to 30 percent moisture.
The 25% level is the average moisture in curing hay at which it is dry enough overall to avoid moulding or hot spots that occur with variations in moisture content that are usually at higher average moisture. Large square bales need to be baled at a lower moisture content than small square or round bales.
