Peer-Reviewed Evidence: Rubber Agroforestry Builds Healthier Soils Than Monoculture

Phosphorus was the one exception, where no significant difference was detected between the two systems, which the authors note may reflect site-specific soil chemistry rather than a systemic pattern.

For Moreganic, this kind of independent data matters. The certification model is built on the premise that agroforestry-based rubber cultivation delivers real ecological value that monoculture systems do not, and that farmers who manage their land accordingly deserve recognition and a verifiable market advantage. Studies like this one strengthen the credibility of that premise with evidence gathered outside any certification framework, in conditions that reflect the reality of smallholder farming in Thailand.

Moreganic does not cite this research as proof that certified farms automatically deliver these outcomes. What certification provides is a structured, audited pathway for farmers to demonstrate that they are managing towards these outcomes, and for buyers to verify that claim. The science provides the rationale; the standard provides the mechanism.
