Any type of water source except rural water can run high in salts. Stock dams are more susceptible than other sources but even wells and spring fed sources can be toxic.
Assessing pasture forage is a key step in planning grazing strategies. The grazing stick utilizes simple plant leaf height measurements in inches. For every inch of growth, the grazing stick estimates how many pounds of dry plant material are available. This number is then represented as pounds per-acre, per-inch of growth.
That first summer we rotated fifty yearlings through six winter pastures. Two years later we were moving 250 yearling steers every two to three weeks through 800 acre pastures. This rotation took us into August when we normally sold the yearlings. We were able to keep the yearling open heifers all summer instead of selling them in the spring.
