SEAWEED EXTRACTS

SEIPASA’s range of seaweed extracts derive from Ascophyllum nodosum. These are collected during the period of maximum nutrient content, then are dried under the sunlight up to a 20% moisture content; cleaned, shredded, desalinised and tattered, undergoing finally a cold extraction without any additives. With the low aggressive extraction processes deployed it is possible to stabilise labile compounds, essential for a high quality seaweed extract.
They contain a high amount of macronutrients, trace elements, amino acids, long chain polysaccharides, antioxidants and phytohormones such as cytokinins, auxins betains and gibberellins. Seaweed extracts are plant based materials, which facilitate their foliar uptake and improve the translocation through the sap to the organs that demand these compounds. The main uses and advantages of this range are summarised below:

  • Increased production by stimulating the hormonal processes of plants. These processes contribute to photosynthesis, nutrient uptake, vegetative growth, flowering, fruit setting and fruit ripening.
  • Provision of trace elements: The different microelements (boron, iodine, copper, magnesium, manganese and zinc) in these products contribute to adjust light nutrient deficiencies. They also contain substances such as mannitol and alginic acid, which contribute to the absorption and translocation of nutrients, due to their chelating properties.
  • Improved frost resistance by promoting plant physiological processes.
  • Quality improvement. Several research projects have shown an increase in sugar content, strengthening of plant tissues and a longer shelf life of harvested produce.
  • They facilitate the processes of germination, vegetative and root development, which makes them of particular interest for organic nurseries.
  • When added at low doses to the spray tank mixture for conventional pesticide treatments, they counteract their negative impact on the crop.
  • Thanks to their high content in oligosaccharides, enzymes and natural plant hormones, they are able to activate the induced resistance mechanisms in plants.
