Summary
The Rodale Institute's Farming Systems Trial (FST), initiated in 1981, is one of the longest-running side-by-side comparisons of organic and conventional arable farming systems in North America. This 40-year report synthesises longitudinal data on crop productivity, soil health, environmental performance, and farm profitability, offering evidence that well-managed organic systems can match conventional yields after a transition period while delivering superior soil carbon accumulation and reduced external input dependency. The report is an institutional publication from a non-profit research organisation rather than a peer-reviewed journal article, and findings should be interpreted with that context in mind.
UK applicability
The trial is conducted in Pennsylvania, USA, under temperate continental conditions broadly comparable in some respects to parts of the UK, though differences in soil type, rainfall distribution, crop varieties, and policy environment limit direct transferability. UK farmers and policymakers may nonetheless draw relevant insights regarding long-term organic transition outcomes and soil health trajectories, particularly in the context of post-Brexit agri-environment schemes and the Sustainable Farming Incentive.
Key measures
Crop yield (t/ha); soil organic matter (%); soil carbon (t/ha); energy input and efficiency; net economic return ($/ha); nitrous oxide and greenhouse gas emissions; water infiltration rates
Outcomes reported
The report documents crop yields, soil health indicators, energy use, and economic performance across organic, conventional, and no-till farming systems over four decades. It likely also reports on greenhouse gas emissions potential and soil carbon sequestration across systems.
