Fully enriched soil-to-health research, interpreted as a practical action plan.

How we tier evidence

1. T1
   Meta-analyses & systematic reviews

   The strongest synthesis of existing evidence. Pre-registered, protocol-led, PRISMA-compliant where possible.
2. T2
   Randomised controlled trials & large cohorts

   Experimental or longitudinal evidence with a control group or baseline. Strong internal validity for causal claims.
3. T3
   Observational studies & field trials

   Cross-sectional, case-control and on-farm field evidence. Useful for association but weaker causal claims.
4. T4
   Narrative reviews, commentaries & policy reports

   Editorial syntheses, guideline documents, industry white papers. Valuable context but lower formal evidence weight.

What makes Pulse Brain different

• Global in scope on soil-to-health evidence.

  The catalogue spans research from every region where soil-to-health evidence is published — 19,000+ curated records across international, European, North American, Asian and African institutions. Not a single-country archive.
• Contextualised to your country.

  Every record is read by Vitagri’s research team and tagged with applicability notes for policy, farming systems and supply chains — the value-add that makes global research actionable on the ground. Tell Pulse the country you work in and the Evidence Base focuses its interpretation there, so the same global catalogue speaks to your context — without limiting who can use it.
• Tier-graded T1–T4.

  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 — farming, soil, nutrition, health.

  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 sources.

  Alongside 19,000+ peer-reviewed studies, Pulse Brain includes approved industry reports, policy briefs and NGO research from 40+ trusted institutions worldwide.
• Continuously maintained.

  New records are reviewed and added every week — pulled from PubMed, CrossRef, OpenAlex, Semantic Scholar and trusted publisher feeds, with manual review before a record goes live.
• Free, citable, machine-readable.

  Every record has a permanent URL and schema.org ScholarlyArticle markup. Academic API access is free globally.
• Vitagri is its own first Pulse Pod.

  Every page on this site, every Insight, and the Growing Health Report itself is composed from Pulse Brain — every claim cited, every record tier-graded. The Vitagri Research Pod is the founding exemplar of the Research Partner programme — the same workflow Research Partners apply to run.
