Seaweed additives can provide micro nutrients, cytokinins, auxins,
gibberellins, polysaccharides, amino acids, and proteins. These are all
very beneficial to plants.
Seaweed products are derived from the soluble ‘extract’ of seaweed species
such as Ascophyllum Nodosum and Laminaria. The extract is widely regarded
as providing the following benefits to plants:
1. Acts as a soil conditioner to increase the cation exchange capacity (CEC)
of soils and aid nutrient uptake.
2. Improves water holding capacity of soils.
3. Promotes the growth of beneficial bacteria.
