One of the world’s most potent organic seaweed fertilisers concentrated into a 100% soluble powder.

Derived from Ascophyllum nodosum, harvested from the clean, cold North Atlantic waters. Available in a 100% soluble powder, which reduces transport costs, this seaweed fertiliser can be used through irrigation or as a highly productive foliar fertiliser. Kelp is a natural source of auxins, cytokinins and gibberellins, and these ingredients, in conjunction with the comprehensive range of trace elements, amino acids and chelating agents found in kelp, can provide many benefits. Kelp also contains complex carbohydrates which are a powerful microbial promotant – the fungal component of the soil can be boosted with Nutri-Kelp™ powder.


  • Australian Certified Organic (ACO) Registered Farm Input 456AI.
  • Can be a valuable rescue remedy during periods of stress.
  • Improves crop quality and associated shelf-life.
  • Boosts soil life activity, particularly the fungal fraction.
  • Reduces maturation time.
  • Increased brix levels may increase cold tolerance in some crops.
  • Offers DIY chelation, as it contains a chelating agent called mannitol.
  • Contains broad-spectrum trace elements in naturally chelated plant available form.
  • Boosts flowering and improves the flower to fruit ratio.

Nutri-Kelp™ is most easily dissolved when sprinkled slowly into a tank/bucket with vigorous agitation/ hand mixing. Additional applications can be made immediately prior to or following stress periods such as frost or drought. It is preferable to increase the frequency of applications rather than the concentration of the solution. Where higher water rates are required for good foliar coverage, do not exceed maximum product rate per hectare. Sensitive foliage or plants should be test sprayed prior to full scale application. Frequencies are a guideline only and can be adjusted according to farm practices and/or in conjunction with crop monitoring. Ensure suitable spray conditions (e.g. temperature, humidity, wind-speed), prior to foliar application. Compatibility and/or performance cannot be guaranteed when combined with other products. Jar test for compatibility and spray test on small area before wide-spread use.

Read safety directions before use. Store in a cool dry area out of direct sunlight. Do not pre-mix or store in diluted form. Seal lid/cap immediately after use.

Not compatible with acidic inputs. Avoid spraying close to harvest if produce is susceptible to staining.
