Seaweed is an important and effective fertiliser containing balanced quantities of Nitrogen, Potassium, Phosphorus, Sulphur, Calcium, Iron, Copper, Boron, Manganese, Magnesium, growth promoters and 17 amino acids.

Also considered a biostimulant due to its high levels of the following plant hormones. 

  • Auxins: Responsible for the growth of plant tissues, cell division, plant movements and plant aging.
  • Gibberellins: Help with seed germination, breaking bud dormancy and fruit development.
  • Cytokinins: Involved in cell division regulation affecting plant growth and rest period. They also inhibit the aging of plant tissues and play crucial role in the transport of nutrients.
