Pulse Brain is Vitagri's curated evidence catalogue — the Growing Health Evidence Index. It aggregates global peer-reviewed studies, industry reports and policy briefs linking soil health, farming systems, nutrient density and human health. Every record is read, tagged, tier-graded, and tagged with UK applicability notes by Vitagri's research team — making international research actionable for UK audiences without limiting who can use it.

How many studies does the Pulse Brain catalogue contain?

The Pulse Brain catalogue currently contains +15,000 curated records — peer-reviewed studies plus approved industry and policy reports. New records are added under a weekly auto-ingest from PubMed, CrossRef, OpenAlex and Semantic Scholar, then manually reviewed before going live.

What do the evidence tiers T1 to T4 mean?

Tier 1 (T1) covers meta-analyses and systematic reviews — the strongest synthesis of existing evidence. Tier 2 (T2) covers randomised controlled trials and large cohort studies. Tier 3 (T3) covers observational studies, field trials and case-control studies. Tier 4 (T4) covers narrative reviews, commentaries, guidelines and policy reports. Every Pulse Brain record displays its tier so readers can weight claims accordingly.

How often is the Pulse Brain catalogue updated?

Weekly auto-ingest, manually reviewed. The auto-ingest pulls new peer-reviewed studies from four academic databases (PubMed, CrossRef, OpenAlex, Semantic Scholar); a parallel industry-reports ingest crawls trusted publishers. Every new record is manually reviewed before going live.

How do I submit a report to the Pulse Brain catalogue?

Institutions, trade organisations, research institutes and NGOs can submit reports at vitagri.org/evidence/submit. Submissions from the 40+ trusted publishers on our registry (including Soil Association, Defra, Nuffield, FAO, IPES-Food, Rothamsted, James Hutton) are fast-tracked. Every submission is manually reviewed before inclusion.

Is Pulse Brain free to use?

Yes. Browsing the catalogue, reading individual records and accessing the API for academic use are all free. Every record is citable via APA, Chicago or BibTeX. The Weekly Evidence Bulletin is also free to subscribe to. Commercial API access is offered for food brands, consultancies and enterprise users.

The Growing Health research programme is published under the auspices of the Frank Parkinson Trust and the Nuffield Farming Scholarships Trust.

What sources does Pulse Brain ingest from?

Peer-reviewed studies are ingested from PubMed, CrossRef, OpenAlex and Semantic Scholar. Industry reports and white papers are ingested from a curated list of 40+ trusted publishers including UK trade bodies (NFU, LEAF), NGOs (Soil Association, WWF-UK, RSPB), research institutes (Rothamsted, James Hutton, NIAB), government bodies (Defra, FSA, NICE) and international organisations (FAO, WHO, IPCC, IPES-Food).

How we tier evidence

T1

Meta-analyses & systematic reviews

The strongest synthesis of existing evidence. Pre-registered, protocol-led, PRISMA-compliant where possible.
T2

Randomised controlled trials & large cohorts

Experimental or longitudinal evidence with a control group or baseline. Strong internal validity for causal claims.
T3

Observational studies & field trials

Cross-sectional, case-control and on-farm field evidence. Useful for association but weaker causal claims.
T4

Narrative reviews, commentaries & policy reports

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

Refresh cadence: Weekly auto-ingest, manually reviewed. +15,000 curated records live.

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 — +15,000 curated records across international, UK, European, US, and Asian institutions. Not a UK-only archive.
UK-contextualised 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 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 +15,000 peer-reviewed studies, Pulse Brain includes approved industry reports, policy briefs and NGO research from 40+ trusted institutions worldwide.
Weekly auto-ingest, manually reviewed.

Weekly auto-ingest, manually reviewed: pulling new records from PubMed, CrossRef, OpenAlex, Semantic Scholar and trusted publisher feeds. Every record is reviewed before going 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 — same workflow the cohort is being recruited to do.
