Magnesium is an essential nutrient in chicken, cattle and other animals’ diet. The lack of magnesium can lead to magnesium deficiency in cattle and eventually to one of the common diseases found in grazing animal, grass tetany. Animals are most at risk in developing such nutritional diseases during the spring and fall season when the natural level of magnesium in their habitat is at the lowest. In order to maintain healthy levels of magnesium in the cattle’s diet a supplementary source is required. Feed supplements are commonly used for this purpose with Magnesium Oxide being the compound of choice due to its high bioavailability, concentration in magnesium and its aid in increasing lactotional performance.
Magnesium is a vital nutrient for the development of plants, since It constitutes the central core of the chlorophyll molecule, it is actively involved in photosynthesis and helps activate many enzyme systems. As a result, magnesium deficiency in plants can lead to hampered growth and poor crop results. To counteract this, Magnesium Oxide is preferably used as a fertilizer by itself or in formulation with others due to its high concentration in Magnesium.
More specifically, Magnesium can help in the stabilizing the ammonium nitrate prills, where the Mg-source (MgO or MgCO3) reacts with nitric acid to produce magnesium nitrate. The latter is in turn incorporated at low amounts in the ammonium nitrate product to protect its structural integrity. Another important application is the use of MgO powders in NPK type fertilizers to either increase the Mg nutritional value or to neutralize excess acidity in the production process.
