5% Magnesium Acetate Fertilizer

Magnesium supports plants by facilitating the distribution of phosphorous throughout the plant. Since phosphorous is essential for developing flowers, fruit and roots, a lack of magnesium results in plants that fail to produce fruit or that are unable to take in enough other nutrients due to an underdeveloped root system. The oldest leaves of a plant with a magnesium deficiency will have edges that appear yellowish, and in the center of each will be a light green area shaped like a lance.

Mg-Ace is an ideal fertilizer for the following soil factors:

  • Soil Mg content: Soils inherently low or high in Mg containing minerals
  • Soil pH: Low soil pH decreases Mg availability, and high soil pH increases availability
  • Soil Mg:Mn ratio: High available Mn can directly reduce Mg uptake. This may be independent of the acid conditions normally associated with excess available Mn in the soil.
  • Soil CEC: Low CEC soils hold less Mg, while high CEC soils can hold abundant Mg. However, if a high CEC soil does not happen to have strong levels of Mg, it will tend to release less of the Mg that it holds to the crop.
  • Cation competition: Soil with high levels of K or Ca will typically provide less Mg to the crop
  • High cation applications: High application rates of other cations, especially K, can reduce the uptake of Mg. This is most common on grasses, and corn seems to be the most sensitive grass.
  • Low soil temperatures
