Round Hay Bales

"Hay bales are not a plant themselves, but a process that takes grasses, or legumes and piles them up for animals to eat in the winter or when in barn stalls. Farmers take a field of grass or legume plants and run a big machine over it and the machine rolls it up as it harvests the plant from the ground. Some machines also till under the rootball and stem, and some machines also grove the ground for the next crop. People can't pick up these round bales, but some plants can be baled and kept in the field, exposed to weather for a year. Most of the time, the outer layers get dried, lose their color and nutrients and get moldy. Some animals can eat the nasty layer, but most prefer the inner areas that have kept their color and nutrients and not gotten moldy." <Source:HeatherMiller>
