As crop yields continue to increase through science and technology, it is more important than ever to be sure our soils and plants are receiving adequate levels of all essential nutrients, including magnesium.
Many types of soil are deficient in magnesium (Mg), particularly sandy soils and soils with low cation-exchange-capacity (CEC), and soils with low pH levels or high alkaline levels. Energy is required for proper plant growth, and crops require Mg to capture energy from the sun for growth and production through photosynthesis. Mg is an essential component of the chlorophyll molecule, the site where photosynthesis occurs. It also acts as a phosphorus carrier in plants, which is necessary for cell division, protein formation, phosphate metabolism, plant respiration, and the activation of several enzyme systems.
Magnesium sulfate (MgSO4) and magnesium oxide (MgO) are the best sources of Mg to accomplish increased food production goals and to provide for the most effective performance in terms of plant availability.
