MagSul

A water soluble crystalline magnesium sulphate heptahydrate (contains 12.9% sulphur + 9.8% magnesium)

Role of Magnesium in the Plant:

  • Forms nucleus of chlorophyll molecule
  • Essential for lush, green growth
  • Helps strengthen the plant’s natural resistance to disease and stress
  • Necessary for phosphate uptake
  • Crucial for protein synthesis

Signs of Magnesium Deficiency:

  • Starts with chlorosis but progressing to complete dying of mature foliage
  • Leaves curl upwards along margins
  • Foliage drops
  • Lack of adequate magnesium will accentuate phosphate deficiency

Advantages of MagSul

  • Completely water soluble - dissolving instantly and remaining in solution
  • Reduces the pH of the spray solution promoting nutrient uptake
  • Enables magnesium uptake by certain plants
  • Contains no sulphates or potentially harmful chlorides
  • May be tank mixed with other foliar feeds
  • Well tolerated by crops
  • Cost effective

Methods of Application

MagSul can be applied as a foliar treatment in a regular spray program or as a corrective spray. It is suitable for ground or aerial spraying. It can also be used in fertigation through an irrigation system, sprinkler or pivot.
