Outstanding Nutrition for Cereals
Helping establish a strong foundation for your cereal nutrition plan starts in the soil.
Sea2Soil is a cold-processed fish hydrolysate soil improver that supports both the soil microbiome and the crop directly. Rich in naturally balanced amino acids and fatty acids, it also contains essential nutrients such as nitrogen, phosphorus, and potassium, alongside bioavailable micronutrients including calcium, magnesium, and other trace elements.
What does Sea2Soil do?
Sea2Soil is a high-quality, cost effective organic soil improver for use in conventional and organic cultivation and amenity management.

“An eco-friendly option that is multi-faceted in its benefits, great quality and easy to use”
We’ve been using Sea2Soil for around three years now as we progress along our regen journey.
Whether you’re a regen or conventional farmer, the product is incredibly useful as an organic fertiliser and soil improver. An eco-friendly option that is multifaceted in its benefits is only going to be something that grows in popularity among farmers as the industry shifts.
The product has always been of great quality and is easy to use – we’re certainly using more of it now than ever before.
The Sea2Soil team is always a pleasure to deal with, the customer service has always been excellent, and delivery is fast too.
How Sea2Soil supports soil & crop function
Fish hydrolysate can be utilised by the soil microbiome and the plant directly. Sea2Soil supports beneficial soil bacteria that convert nutrients into a form readily available to the plant, helping crops function and grow more efficiently.
Sea2Soil contains a full range of naturally balanced amino acids. L-amino acids can be taken up by the plant directly for protein synthesis, while D-amino acids support soil bacteria and soil health.

Tank Mix Compatibility
Sea2Soil is compatible with a wide range of products, including certain fungicides, herbicides, and PGRs.
When tank-mixed with herbicides in foliar applications, the fish oil content acts as a natural surfactant, which can enhance spraying performance.
For full details on the latest compatibility testing, please contact us. It is advisable to complete a simple compatibility bucket test before mixing in the sprayer tank.
For more specific guidance, don’t hesitate to contact the team.

Frequently Asked Questions
Can Sea2Soil be applied through fertigation or drip irrigation systems?
Yes, Sea2Soil runs cleanly through drip and micro-irrigation lines. Flush the line with clean water after each fertigation run to prevent bio-film accumulation inside drip emitters.
Can Sea2Soil be tank-mixed with standard liquid inputs or biologicals?
Yes, Sea2Soil is compatible with most organic inputs, compost teas, and bio-stimulants. Always conduct a standard jar test before large-scale tank mixing, and avoid combining with high-pH alkaline chemicals.
Can Sea2Soil help reduce overall synthetic nitrogen requirements?
By optimizing soil biological function, Sea2Soil unlocks bound nutrients in the soil matrix. Trial data indicates growers can safely reduce synthetic nitrogen inputs by 15–25% without sacrificing yield potential.
How does liquid fish hydrolysate differ from standard fish emulsion?
Fish emulsion uses high-heat processing that strips valuable proteins and oils. Sea2Soil utilizes a cold enzymatic hydrolysis process that preserves whole fish proteins, amino acids, enzymes, and natural lipids vital for soil microfauna.
How does Sea2Soil help build soil organic matter over time?
By feeding native mycorrhizal fungi and beneficial soil microorganisms, Sea2Soil accelerates biological humification. Over consecutive seasons, increased biological activity locks stable carbon into the soil profile.
How does Sea2Soil support microbial life compared to synthetic fertilizers?
Unlike synthetic NPK inputs which bypass soil biology, Sea2Soil is a cold-processed liquid fish hydrolysate rich in proteins, amino acids, and trace elements. It directly feeds soil fungi and beneficial bacteria, restoring degraded soil food webs.
How should Sea2Soil be stored during freezing winter conditions?
Protect containers from hard, prolonged freezes. If the product freezes, allow it to thaw naturally at ambient temperature and agitate or recirculate before use to ensure full re-homogenization.
Is Sea2Soil suitable for certified organic farming systems in the UK?
Sea2Soil is processed naturally from sustainably sourced fish waste without synthetic chemical digestion, meeting OF&G organic standards for soil conditioners and natural bio-stimulants.
Is Sea2Soil suitable for fine turf and sports pitch maintenance?
Sea2Soil improves sward density, enhances root depth, and reduces reliance on synthetic liquid feeds that cause soft, disease-prone growth flushes on turfgrass.
What impact does Sea2Soil have on root architecture in potato crops?
Sea2Soil stimulates early root elongation and secondary fine lateral branching. A denser root network allows the crop to scavenge soil phosphorus and moisture far more efficiently during tuber initiation.

The story behind the success
Pelagia has 28 operating facilities across Norway, Europe and the United Kingdom, processing over 1 million tonnes of fish and fish by-products per annum. Pelagia is committed to zero waste from this industry, which is where Sea2Soil comes in. In fact, it’s a key part of this strategy.
In 2019, our processing facility in Bressay, on the Shetland Isle, expanded it operations and obtained a license to utilise unused fish by-products to create a highly nutritious soil improver.
