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.
1 Pulse crops are versatile, adding flexibility to cropping systems. 2  If growing conditions turn dry, pulse crops can be harvested or grazed for forage or terminated to conserve soil moisture-the soil will still benefit from nitrogen fixation, rotation, and having a cover crop. Pluse crop acres have increased from 350,000 in 2009 to over 700,000 in 2014. 2  Pulse crops require little (if any) nitrogen fertilizer; instead they fix nitrogen from the air into the soil. 3  Pulse crops help break disease and pest cycles in wheat and barley.
