Can K-Mag Fertilizer be used to protect cattle from grass tetany?
Researchers have determined that the condition is linked to a shortage of magnesium and calcium in forages. However, their work shows that grass tetany is more than simply a magnesium deficiency. Without sufficient phosphorus, grass tetany may result even if soil magnesium is adequate. Phosphorus promotes the uptake of magnesium and calcium as its levels are increased and the two nutrients move to the leaves. In a three-year research study of phosphorus influence on phosphorus, potassium, calcium and magnesium concentrations in ryegrass and Coastal bermudagrass, applied phosphorus increased tissue magnesium concentrations. Applying phosphorus and magnesium may not completely alleviate the potential for grass tetany, but applications of both nutrients may help correct the problem. The first step in preventing grass tetany is to use a balanced fertility program, which starts with a soil test. Establish the fertility status of the soil and then determine the desired yield level.
