Grown, harvested and pressed on Sandhornøya, Northern Norway
Seaweed biostimulants for root growth and stress resilience.
We make bioactive seaweed compounds and phytohormones accessible to crop plants, supporting nutrient efficiency, plant resiliency, and stabilized yields during stress. Available directly to distributors, formulators and farmers.
Worldwide shipping available.
Rockweed at low tide outside our door. We cut it by hand, and it is pressed the same day - gently, so no fragile compounds are lost or damaged from harsh extraction methods.

(b) Trial evidence
Controlled drought stress, mustard trial
Mustard (Brassica juncea) in hydroponics, foliar-treated with 0.3% KelpAGRI-Asco every 5 days for 3 weeks. Treated plants outperformed both the water control and a competitor alkaline-extracted product.

How it works
Biology, not fertilizer
A biostimulant stimulates natural plant processes independently of nutrients to improve nutrient efficiency, tolerance to abiotic stress, crop quality and yield — as defined by EU Regulation 2019/1009 and the U.S. Farm Bill (2018).
Bioactive compounds such as polysaccharides, betaines and plant-hormone-like substances stimulate root initiation, elongation and branching. A larger, more efficient root system increases water and nutrient uptake and strengthens tolerance to drought, salinity and temperature extremes (Mukherjee & Patel 2020; Salehi et al. 2019; Sujeeth et al. 2022).
Growth and yield
Boosts root growth, leading to increased flowering and fruit yield in both quantity and quality.
Stress tolerance
Treated plants show enhanced resilience to salinity, drought, heat and cold.
Disease resistance
Elevates plant resistance against pathogens including powdery mildew and grey mould.
Nutritional enhancement
Increases mineral content in crops, enhancing nutritional value and crop quality.
Water and nutrient efficiency
Improves uptake of water and essential elements, making your existing programme work harder.
Environmental impact
A sustainable path to meet global food demand while reducing greenhouse gas emissions.

I am very happy with the product. I have never had this much root growth and early growth as this year.
