Magnesium

We supply high quality Magnesium which is required for crops to capture the sun's energy for growth and production. Its functions include phosphate metabolism, plant respiration and activation of enzyme systems. Magnesium can be added to deficient soils by applying Mg-containing fertilizers or dolomitic limestone. Dolomitic limestone contains both Ca and Mg Carbonates (for neutralizing value), whereas calcitic limestone contains only Ca carbonate. Availability of Mg is often related to soil pH. Other situations also increase needs for Mg : sandy soils with low cation exchange capacity, low Mg-supplying power, and a high Mg leaching potential, application of calcitic limestone on low Mg soils, crops with high Mg requirements, high application rates of ammonium-N and K, soil test levels below 50 to 100 Ib/Aexchangeable Mg.
