100% - Soluble Sea Kelp is a bio-stimulant designed to be used as part of a well-balanced plant nutritional program. Our animal free, plant derived Icelandic kelp, Ascophyllum Nodosum, stands out as being of the highest quality sourced from ethically harvested locations.

Sea kelp is perhaps the oldest known agricultural supplement. Its benefits are well documented over the centuries, across cultures and nations. Among the essential minerals, vitamins, enzymes and amino acids that kelp provides lies all natural plant growth hormones. This translates to healthier crops, more flower sites, increased fruit size with a boost to immunity against disease, unwanted fungal infection and pest infestations. Every crop will benefit from the addition of sea kelp. Treatments of our Soluble Sea Kelp increases propagation rates of cuttings, seeds and transplants.

  • Agronomic Crops: 1-3 lbs.  per acre (1 kg. per hectare).
    Apply 25-75 gallons diluted Solu-Sea per acre (100 liters diluted Solu-Sea liquid solution per hectare)

  • Turf: 3-5 lbs. per acre (1-2 kg. per hectare).
    Apply 75-125 gallons per acre (100-200 liters diluted Solu-Sea per hectare)

Always shake, or mix, reconstituted Solu-Sea well before diluting.  Only make up what you can use at one time.  Foliar application is the most efficient and effective method.  Kelp extracts are 8 to 20 times more effective when applied to the leaves then when broadcast on the soil.  Spray as a fine mist until it drips of the plants’ surfaces.

SPRAY INSTRUCTIONS:  Reconstituted Solu-Sea can be used with a variety of sprayers – plant misters, pump-up, backpack, hose-end, or tractor sprayers.  The dilution rates provided here are based on areal measurements.  Depending on the type of sprayer you have, simply dilute this product with the appropriate amount of water for your sprayer to cover a specific area.  This product also works well with irrigation systems.
