Summary
This paper, published in Biological Control in 2015 by USDA researcher R.P. Larkin, examines the use of biological soil amendments — including compost, green manures, biocontrol organisms, and other organic inputs — to suppress soilborne pathogens and improve productivity in potato systems. The research likely presents field trial data comparing amendment treatments against conventional controls, with implications for integrated disease management. It contributes to the evidence base for reducing chemical inputs in potato production through ecologically based soil health interventions.
UK applicability
Although conducted in the United States, the findings are broadly applicable to UK potato production, where soilborne diseases such as Rhizoctonia solani and common scab are significant concerns; UK growers and agronomists may draw on the amendment strategies evaluated, though soil type, climate, and regulatory contexts would require local adaptation.
Key measures
Disease severity ratings; plant emergence and yield (t/ha); soil microbial community indicators; disease suppression indices
Outcomes reported
The study likely evaluated the effects of biological soil amendments — such as compost, biocontrol agents, and organic inputs — on soilborne disease suppression, soil health indicators, and potato yield. It may have assessed disease incidence (e.g. Rhizoctonia, Fusarium, common scab) alongside plant performance metrics.
