Two cold-pressed lines. Prevention and recovery.
Both suspensions are obtained through a particularly gentle, purely physical cold-pressing process. The temperature never exceeds 40 °C, preserving the full effectiveness of every valuable component. Use stand-alone, or as the base for your own blended product.
KelpAGRI-Asco
Kelpinor Ascophyllum nodosum suspension
A high-quality organic biostimulant, rich in natural bioactive compounds that improve plant growth and stress tolerance. Formulated from rockweed hand-harvested along the northern Norwegian coastline.
CE certified to increase fresh biomass, leaf area, leaf length, root length and greenness in salads under low-light stress. Increases growth, germination success and improves plant hormone balance. All ingredients are suitable for conventional farming and FiBL approved for organic farming.
Product data
Usage · Asco & Alaria
- Foliar application
- Seed treatment
- Multiple low-dose applications recommended
- Small jar test before tank mixing
- Do not store as diluted solution
Why rockweed
Rich in polyphenols and fucoidan: reduces oxidative damage from UV, nutrient fluctuations and other environmental stress. Rich in alginates that improve water retention, air circulation and microbial activity in soil.
KelpAGRI-Alaria
Kelpinor Alaria esculenta suspension
Our next-generation biostimulant, formulated from sustainably farmed winged kelp from the Norwegian coastline. Developed to improve root elongation, nutrient efficiency and recovery from drought — helps push the yields.
Alaria esculenta is unique in its high protein and high iron content, and clearly stands apart from other seaweed biostimulants on the market.
Product data
Why cultivated seaweed
- Scalable: a secure source of biomass for the future
- Unique species, unique biostimulant composition
- High biochemical consistency from tailored harvest schedules
- Reduced pressure on the wild coastal environment

In the field
Made for real-world farming
KelpAGRI is built for open-field agriculture first — it fits standard spraying and application equipment on working farms, and works equally well in fertigation and hydroponic systems.
Foliar application
A 0.3% dilution applied with standard spraying equipment.
Field by field
Response shows in roots, leaves and standing crops through the season.
Through to harvest
Resilience and yield quality carried all the way to harvest.
Research & development
Controlled environment testing
Every claim is backed by in-house trials in hydroponic setups and by third-party certification. Below are headline results from our drought, foliar, germination and light-stress experiments.
Drought stress · mustard
265 vs 210 cm²
final leaf area, treated vs control · avg leaf length 7.8 vs 5.6 cm
Foliar 0.3% every 5 days for 3 weeks. Water supply cut at 3-leaf stage.
Germination · seed bath
89% vs 55%
germination rate, treated vs water control
Seeds bathed 20 min in 0.3% KelpAGRI-Asco, 5 days at 15 °C.
Light stress · cress
Root ↑ Leaf ↑ Stem ↑
improved root growth, leaf area and stem length vs untreated
Foliar 0.3% KelpAGRI-Alaria under 700–800 µmol/m²/s in standard hydroponic solution.

Seaweed biostimulants aid agricultural sustainability
Biostimulants don't replace fertilizers — they make them work better. Our gentle cold process protects sensitive bioactive compounds from heat and harsh chemicals, keeping their full range of plant-supporting benefits.
Microbiome regulation
Encourages a healthy mix of soil and root microbes that support plant growth.
Phytohormonal regulation
Helps balance natural plant hormones to improve development and metabolism.
Phytostimulation
Boosts nutrient uptake, photosynthesis, stress tolerance and yield.
Phytoelicitory responses
Strengthens the plant's own defences against pests, diseases and drought or cold.
Impact on the planet
Our mission is to make biostimulants mainly from farmed seaweed — a commitment to sustainable and responsible use of marine resources.
Healthier soils & crops
Improves soil structure and plant strength, reducing the need for synthetic fertilizers that harm water and wildlife.
Support for marine life
Sustainable seaweed farming avoids overharvesting wild stocks and creates habitats that support marine biodiversity.
Climate-friendly farming
Seaweed absorbs CO₂ from the atmosphere, helping reduce greenhouse gases.
Cleaner waterways
Better nutrient uptake means less fertilizer runoff, keeping rivers and oceans clean.

Straight answers for growers
How fast will we see results?+
Early signals appear within 72 hours.
- Root activity shifts within days
- Leaf thickness and posture change quickly
- Yield and structural gains depend on crop cycle
We already use beneficial microbes — will it interfere?+
It enhances microbial systems, not competes.
- Acts as a prebiotic substrate
- Stimulates root exudation
- Improves rhizosphere colonization
Does it work in high-EC or recirculating systems?+
Yes — high-EC is where it shines.
- Supports osmotic balance and salt tolerance
- Stabilizes root microbiome under recirculation stress
- Improves rhizosphere colonization
Will this clog my lines?+
Clogging has not been a general issue, but compatibility depends on what the product is mixed with and at what concentration.
- Made primarily for outdoor agriculture
- Can also be used in fertigation and hydroponic systems
- Check compatibility with your specific mix and application rate before use
Biostimulants are snake oil.+
Modern biostimulants are legally and scientifically defined.
- EU/US regulate them based on plant physiological action
- Backed by peer-reviewed studies on SAR and hormone signaling
- Built on real plant signal transduction research
We need real numbers, not stories.+
We generate instrument-grade, data-logged results.
- Controlled CEA trials with imaging and analytics
- Track EC drift tolerance, stress recovery, flowering onset
- We speak in micromoles, not marketing
We've tried kelp products — they never worked.+
Most kelp extracts lose their actives — ours doesn't.
- Others are processed above 70°C → degraded signalers
- We cold-press below 40°C to preserve bioactive complexity
- Multiple species for broader biological activity
We can't disrupt our nutrient program.+
You don't have to — this isn't a nutrient.
- Works as a signaling modulator, not a fertilizer
- Enhances uptake efficiency of your existing program
- No need to change fertigation ratios
