The Story Behind The Success The Story Behind The Success
The last 5 years has been thanks to a century of knowledge & understanding.
Partnering & collaborating with the most influential institutions in the UK.
Sea2Soil’s parent company, Pelagia, has been utilising fish and fish by-products to produce valuable, highly nutritious feed materials for over a century.
An environmentally friendly alternative to synthetic fertilisers, fish hydrolysate utilises responsibly sourced by-products from the aquaculture industry to support a more sustainable, zero-waste product for agriculture.
It’s all about the soil…
Utilised by the soil microbiome and the plant directly, Sea2Soil contains a full range of naturally balanced amino acids, fatty acids and essential macro and micronutrients in a bioavailable formulation, establishing a good basis for any crop nutritional plan. Sea2Soil is also highly versatile, easy to use and suitable for all farming systems including organic, conventional and regenerative. The product has been developed with a science-based, research-led approach combining high-quality R&D formulation with trials work, where it has been tested and proven in the field over more than 5 years.
Traditional methods meet innovation
It may have all started as a happy coincidence centuries ago, when farmers observed that plants performed better when decomposing fish were left near them, but thanks to science and research, we now have a good understanding of how fish material positively affects crops and the soil that supports them.
The UK’s Only Organic Soil Improver
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. In 2023, we garnered the prestigious accolade of certified organic, and we are officially the sole organic fish hydrolysate in the UK.
North Lincolnshire
We use fish hydrolysate in three ways. The main one has traditionally been to ‘apologise’ for moving the soil.
In the early transitional years of direct drilling, when there may be a need for low-disturbance subsoiling, we need to feed soil microbes so they don’t begin to destroy soil organic matter. You are providing them with another food source.
Once through that stage, we are attempting to correct the soil microdome from one that has become bacterial dominant to one where you enable protozoa to feed on the bacteria, creating a more balanced or even fungal-dominant structure, again by feeding the soil microbes. We do this by adding Sea2Soil to a cocktail that can be placed around the seed at drilling.
Thirdly, we have noticed how quickly plants absorb fish hydrolysate as a food source. Unlike artificial fertiliser, which has to be processed within the plant and thus has an initial energy-hungry phase, weakening cell structures, Sea2Ssoil, with its high volume of amino acids, quickly gets into the crop and can rectify deficiencies and combat things like cabbage stem flea beetle in oilseed rape.
By creating a more balanced plant, the need for higher volumes of nitrate can be offset.
Closing the loop Closing the loop
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.
Give your crops all the support they need by directly improving your soil health
Derived from fish hydrolysate, Sea2Soil’s nutritional profile naturally contains both organic compounds (amino acids and fatty acids) and a wide range of mineral nutrients.
Providing amino acids in two forms – L‑amino acids that can be taken up by plants and used in protein synthesis, and D‑amino acids, which are primarily utilised by soil bacteria, supporting the soil microbiome – Sea2Soil also delivers a balanced range of macronutrients, secondary nutrients and trace elements that underpin key plant and soil processes including root development, chlorophyll formation, enzyme function, soil structure and stress response.

A winning formula for crops
Utilised by the soil microbiome and the crop directly…
The fish hydrolysate contains a full range of naturally balanced amino acids and fatty acids, establishing a good basis for any nutritional plan.
Amino acids naturally occur in two forms and play a key role in soil and plant health.
L-amino acids are taken up by plants directly and used for protein synthesis. D-amino acids are used by soil bacteria, crucial to soil health.
Each amino acid has specific functions in plant metabolism, growth, and stress response.
A balanced supply of essential amino acids is crucial for optimal crop growth and development.
Sea2Soil contains all 20 amino acids needed for protein synthesis, in both L and D forms

Everything your crops need for optimal production
Feeding your crop starts with feeding the soil. And in healthy soils, nothing works in isolation; plants need a balanced, reliable supply of nutrients to grow, establish roots, build biomass, and withstand pressure from weather, pests, and disease.
Balance
Sea2Soil brings that balance together in one product, combining key building blocks (like carbon and nitrogen) with the secondary and micronutrients that unlock uptake, efficiency, and resilience.
Positively contributing to performance
Delivering a wide range of nutrients that contribute to soil function and plant performance — from supporting soil organic matter and structure, to enabling chlorophyll production, enzyme activity, and efficient nutrient use, the application of Sea2Soil supports the creation of a more resilient growing environment and a crop that can do more with what’s available.

A business built on nature to to benefit us all
Better soil
Enhancing soil biology, promoting beneficial microorganisms and earthworms
Biologically active soils reduce fuel consumption through increased porosity and faster straw breakdown, resulting in easier workable soils. Enhanced soils then retain moisture and release nutrients, creating healthier, more naturally resilient plants, improving plant growth and carbon retention. By providing nutrients in a bioavailable form, Sea2Soil can improve vital soil health indicators such as soil organic matter, microbial biomass, beneficial bacteria, fungi and soil protozoa. As a highly rich source of essential amino acids, Sea2Sil also helps rebalance soil biology, creating a healthier soil and more productive crops.
Better plants
Promoting root growth and plant resilience
Making a stronger and healthier plant ecosystem relies on the presence of essential amino acids, just like those found in Sea2Soil, which can actively help enhance plant resilience and stimulate better natural responses to biotic and abiotic crop stresses. Better root structure also aids better drought and flooding tolerance by improving the overall structure of your soil. As a product integrated into your farming system, Sea2Soil essentially acts as a probiotic for your soil, feeding crops more efficiently to help them reach their full potential.
Better farming
Easily incorporated into all farming systems
Sea2Soil is filtered to 100µm, making it easy to apply via farm sprayers and other liquid applicators. Compatible with most commonly used tank mixes and most foliar nutrition and plant protection products, Sea2Soil can be delivered on farm in IBCs, Bulk, and 25kg tubs. Utilising fish hydrolysate not only improves sustainability but also helps grow healthier crops across all farming systems, reducing reliance on synthetic fertilisers and improving investment returns.
Better support
Reliable UK-based manufacture and supply
Supporting crops effectively is more important than ever as farm input costs continue to rise and margins are squeezed even further. With processing and storage facilities across the UK, Pelagia provides a fast and reliable delivery system to help protect farmers from global volatility that can affect the supply of synthetic fertilisers. Reducing over-reliance on synthetic fertilisers by turning to the sustainable, UK-based Sea2Soil is a cost-effective way of applying key nutrients, while presenting the opportunity to farm with a positive environmental impact, creating lasting change.
