Cover Crop Bonus
 Cover crops are popular with organic growers because they
provide an ecologically sound way to control crop-destroying insects.
 There are some other effects that are also pleasant. Butterflies
find cover crops especially attractive and, being quite attractive themselves,
they bring their own beauty to the cover crop.
