The world’s largest curated catalogue of research linking soil health, food quality & human wellbeing.

How we tier evidence

1. T1
   Meta-analyses & systematic reviewsThe strongest synthesis of existing evidence. Pre-registered, protocol-led, PRISMA-compliant where possible.
2. T2
   Randomised controlled trials & large cohortsExperimental or longitudinal evidence with a control group or baseline. Strong internal validity for causal claims.
3. T3
   Observational studies & field trialsCross-sectional, case-control and on-farm field evidence. Useful for association but weaker causal claims.
4. T4
   Narrative reviews, commentaries & policy reportsEditorial syntheses, guideline documents, industry white papers. Valuable context but lower formal evidence weight.

What makes Pulse Brain different

• Global in scope. The catalogue spans research from every region where soil-to-health evidence is published — over 1,993 records across international, UK, European, US, and Asian institutions. Not a UK-only archive.
• UK-contextualised as an interpretive layer. Every record is read by Vitagri’s research team and tagged with applicability notes for UK policy, farming systems and supply chains — the value-add that makes global research actionable for UK audiences, without limiting who can use it.
• Tier-graded. Not all evidence is equal. Each record carries a T1–T4 grade derived from study type and design, so readers can weight claims accordingly.
• Cross-domain. Most catalogues specialise in either agriculture or nutrition. Pulse Brain integrates farming systems, soil biology, nutrient density, food quality and human health in one register.
• Industry plus peer-reviewed. Alongside 1,610+ peer-reviewed studies, Pulse Brain includes approved industry reports, policy briefs and NGO research from 40+ trusted institutions worldwide.
• Weekly refresh. A Sunday-evening ingest pulls new records from PubMed, CrossRef, OpenAlex, Semantic Scholar and trusted publisher feeds. Manually reviewed before going live.
• Free to browse, citable, machine-readable. Every record has a permanent URL and schema.org ScholarlyArticle markup. Academic API access is free globally.
