Certifications & quality assurance
Certifications & quality assurance
When you choose an organic fertiliser, you need to know that what is on the label matches what is in the bag. At SoilWorx, all our crop nutrition products are independently certified, rigorously tested and fully compliant with UK and EU regulations. Our certifications are not marketing badges: they are evidence of the standards we hold ourselves to every single day.
OMRI listed
Some SoilWorx crop nutrition products are listed by the Organic Materials Review Institute (OMRI), an internationally recognised, independent organisation that evaluates products for use in organic agriculture. OMRI listing means our fertilisers have been reviewed against strict organic standards and approved for use in certified organic production.
For growers, agronomists and land managers, OMRI listing provides confidence that SoilWorx fertilisers meet the rigorous input requirements of organic certification bodies worldwide.
Other SoilWorx crop nutrition products are both OMRI listed and certified by the Organic Trust, an established organic certification body operating across the UK and Ireland. Organic Trust certification confirms that our manufacturing processes, raw materials and finished products meet the standards required for organic agriculture.
This certification is maintained through regular audits and inspections, ensuring ongoing compliance rather than a one-off approval.
Organic Trust certified

Our quality testing process
Quality at SoilWorx is not left to chance. Every production batch goes through a defined quality assurance process:
Raw material inspection
Incoming organic materials are assessed for quality and suitability before processing begins.
Heat treatment and sterilisation
All materials are processed at controlled temperatures to eliminate pathogens, weed seeds and harmful organisms.
Nutrient analysis
Finished products are tested for nitrogen (N), phosphorus (P), potassium (K), organic matter content and micronutrients.
Independent laboratory testing
Samples from every batch are sent to state-approved laboratories for independent verification.
Batch traceability
Every bag can be traced back to its production batch, providing full transparency from raw material to finished product.

- The product is genuinely organic: verified by independent third parties
- The nutrient analysis is accurate: confirmed by independent laboratories
