But the gravitational force exceeds it and the water is pulled toward the moon, causing a bulge of water on the near side toward the moon (Ross, D.A., 1995). On the opposite side of the Earth, or the far side, the gravitational attraction of the moon is less because it is farther away.Here, inertia exceeds the gravitational force, and the water tries to keep going in a straight line, moving away from the Earth, also forming a bulge (Ross, D.A., 1995).ravity, Inertia, and the Two Bulges. Two tidal bulges are created on opposite sides of the Earth due to the moon's gravitational force and inertias counterbalance. Click the image for a larger view.
To take a closer look at the issue of alfalfa seeding rates, letâs start at the beginning with the seed itself. One of my references indicates that there are 199,000 alfalfa seeds per pound. If that one pound was evenly spread over one acre (43,560 ft.2), there would be in the neighborhood of five seeds per square foot.
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.
