Triticum compactum Triticum compactum Triticum compactum or club wheat is a species of wheat adapted to low-humidity growing conditions. "T. compactum" is similar enough to common wheat ("T. aestivum") that it is often considered a subspecies, "T. aestivum compactum". It can be distinguished by its more compact ear due to shorter rachis segments, giving it its common name. In the United States of America, nearly all "T. compactum" is grown in dry areas of the Pacific Northwest. "T. compactum" is a hexaploid with 21 chromosomes. "T. compactum", like other club wheats, has been selectively bred for its lower protein content. Due to
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
