Magnesium sulfate fertilizer is designed to easily correct or prevent magnesium deficiencies for all types of crops and soil conditions. The fertilizer is best used to prevent magnesium deficiencies before or during planting, however it can also be used to correct growth problems during the growing season.

Description

In general, palm trees are prone to magnesium deficiency, which causes the margins of older fronds to turn yellow or orange, while the centers of the fronds remain green. Magnesium sulfate, also known as Kieserite or Epsom salt, can help prevent magnesium deficiency in palms. Once the symptoms of magnesium deficiency appear, the condition is difficult to reverse. Regular applications of magnesium sulphate will provide the nutrients that palm trees need to produce healthy, green fronds, but it may take up to two years for the new growth to replace the older fronds. Although the fronds are unsightly, magnesium deficiency is not fatal. 

Magnesium Sulphate is widely used for oil palm plantations in South East Asia.

It has many functions in the metabolism of oil palm:

  • magnesium is the central atom of the chlorophyll molecule, the green pigment in leaves, which captures the light energy required for photosynthesis
  • magnesium is involved in the carboxylase reaction of the photosynthesis, namely as a coenzyme in the fixation of CO2
    magnesium is needed in all processes that require energy, e.g. starch, protein and vitamin synthesis
  • magnesium speeds up the assimilate transport to leaves and fruit bunches and it is required in many enzymes concerned with fatty acid and oil biosynthesis
