One of the characteristics is they contain genetic material (DNA), which is a characteristic that all living things must have in order to be considered living.   And also wâ¦hen inside a host, they are able to reproduce, which all living things must be able to do. Hasmida Muhamad.
When milk prices are low, dairy producers begin to look for ways to reduce the direct input expenses of growing alfalfa. One option that growers have is to purchase lower cost alfalfa seed. Alfalfa seed of modern varieties can cost over $4.00 per pound, while older varieties can be purchased for $2.00 per pound or less.
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.
