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 appropriate moisture level will depend on the type of baler you use. If you have a large hard-core round baler, 15% moisture is optimum. At this moisture level, the bales will keep for an extended period of time. See the chart below for other bale size-moisture contents.
