Ram pumps use the energy of falling water from springs, ponds or creeks to pump the water to a higher elevation, without the need for an external energy source. The fall from the water source must be at least 2-3 feet, and a minimum of 1 gallon per minute flow is required. The energy of one-foot fall will pump the water vertically ten feet. Graziers' Comments Ed Heckman Wayne County Extension Educator Grazing begins in the spring when the forage is less than three inches tall. The reason you do this is to establish an uneven growth cycle in your paddocks, so that all of them aren't ready for grazing at the same time.
Livestock remove less than ten percent of the forages' phosphorus and potassium.
You have to decide based on the forage regrowth. Low stocking rates, which tend to produce high animal performance, tend to also produce low-quality, poorly tillared, open grass swards. Legumes leave the sward because of shading. Start rotational grazing on a small acreage. This is a low investment for an experiment.
