Outstanding Nutrition for Potatoes
Helping establish a strong foundation for your potato 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.
Why potato growers use Sea2Soil
Supports soil biology and nutrient cycling
Sea2Soil provides a highly nutritious food source for soil microorganisms.
Beneficial soil bacteria help convert nutrients into forms readily available to the plant — supporting more efficient crop function and growth.
Strong nutritional base
Sea2Soil contains essential nutrients and bioavailable trace elements.
This helps boost and replenish soil nutrient content and support optimal plant health and growth.
Best used early when the crop is establishing
In all crops, it is better to apply Sea2Soil early while the crop is young and first establishing.
This optimises soil health benefits and gives maximum advantage when the crop really needs it.
Convenient, versatile application
Sea2Soil is easy to apply.
It’s compatible with many plant protection products for added convenience (with sensible checks and guidance).
Recommended usage rates and timings for Potatoes
Spring provides an ideal time to boost soil health and optimise early crop nutrition in newly growing crops. This process can take time depending on soil conditions (for example, temperature and moisture), so earlier applications help maximise benefit.
Potatoes
Spray 10 L/ha (soil applied) pre-emergence, or as soon after drilling as possible. Follow up with up to 10 L/ha in late spring.
Contact the team if you’d like help sense-checking timings against drilling date and your late-spring programme.
Foliar Application
5 to 10 L/ha rn*Multiple applications can be made in the season — up to 6 times a year.
Direct Soil Application
10 to 20 L/ha
Recommended Dilution
1:250 in 100-200L/ha water
How Sea2Soil supports soil and 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.
Application Methods & Practical Guidance
Sea2Soil can be applied (after dilution) in different ways: directly to the soil, as a foliar spray, or through irrigation systems.
Suitable Irrigation Systems
- Direct-to-soil application methods
- Drill-mounted liquid fertiliser applicators
- Fertiliser streamers
- Foliar application methods
- Standard hydraulic crop sprayers
- ‘Tow & fert’ type systems (for applying with other fertilisers or plant protection products)
Filtration / equipment
Filtration and sprayer care: Sea2Soil is pre-screened (filtered) to 100μm but may contain larger particles. Screening is recommended prior to application through fine filters, and filters within the equipment should be thoroughly cleaned after each use.
Important Note
Always seek advice from your agronomist before applying Sea2Soil for use in organic production.
Not to be applied to any edible parts of crops.
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.
