Triticum compactum erinaceum Triticum compactum erinaceum Triticum compactum erinaceum, also called California Club Wheat or Mayview wheat, is an extinct subspecies of the hexaploid club wheat Triticum compactum. "T. compactum erinaceum" was a bearded, hairy rachis, red-chaffed wheat named for its appearance similar to that of a hedgehog. "T. compactum erinaceum" was thought to have disappeared before 1822. However data from the United States Department of Agriculture indicates two additional specimen that were discovered and identified as "T. compactum erinaceum" more than a hundred years after their presumed disappearance. The new specimen indicate that "T. compactum erinaceum" was grown in the United States
Crop rotation crop rotation comes from the interrelationship of nitrogen fixing-crops with nitrogen demanding crops. Legumes, like alfalfa and clover, collect available nitrogen from the soil in nodules on their root structure. When the plant is harvested, the biomass of uncollected roots breaks down, making the stored nitrogen available to future crops. Legumes are also a valued green manure: a crop that collects nutrients and fixes them at soil depths accessible to future crops. In addition, legumes have heavy tap roots that burrow deep into the ground, lifting soil for better tilth and absorption of water. Cereal and grasses are frequent cover
