A frenulum (or frenum) is a small fold of tissue that prevents an organ in the body from moving too far.
Cover crops usually are grown to prevent soil loss from wind and water erosion. Use fast-growing cover crops, such as winter wheat or annual rye, on fall-spaded gardens. A second, and probably more important reason home gardeners should use cover crops is to improve soil structure and increase organic matter.
Crop production covers a wide range of crops which include both cash and food crops. The crops grown include: sorghum (sorghum bicolor); maize (zea mays); cassava (manihot esculenta), common beans (phaseolus vulgaris); field peas (pisum sativum); potato (solanum tuberosum); finger millet (Eleusine coracna) and coffee (coffea canephora or Robusta coffee) and bananas (Musa spp).
