Muscular System. The muscular system is composed of more than 600 muscles. These include the involuntary muscles of the heart and the smooth muscles of the internal organs. The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement.
One cup of alfalfa sprouts contains 1.3 grams of protein. Alfalfa sprouts are the shoots of the alfalfa plant, harvested before they become the full-grown plant. Because they are so small, the sprouts contain a concentrated amount of certain vitamins and minerals such as calcium, vitamin K and vitamin C. Alfalfa sprouts contain just 8 calories and 0 grams of fat per cup.
Nitrogen. Alfalfa is a legume that can fix its own nitrogen (N) with the help of Rhizobium meliloti, a bacteria that lives in association with alfalfa roots. The bacteria converts nitrogen gas (N 2) in the air into a form that plants can use. A 5 ton/ac alfalfa crop will fix up to 250 lb/ac of nitrogen per year.Since the soils in southern Alberta are low in N-fixing bacteria, alfalfa seed must be inoculated with the R. meliloti. Alfalfa seed is often pre-inoculated before sale.pplying nitrogen fertilizer on healthy alfalfa stands is not recommended. Phosphorus. If phosphate was not applied before seeding or is limiting production, a grower may consider an annual maintenance application of 50 lb/ac of P 2 O 5 to meet crop removal rates.
