Anaerobic soil disinfestation (ASD) and microbial soil inoculation are emerging, NOP-compliant alternatives to soil fumigation for managing soilborne pests, weeds, and diseases. In this study, researchers at Virginia Tech evaluated the efficacy of ASD (with and without microbial soil inoculation) and chemical soil fumigation as strategies for managing fruit rot, weeds, and post-harvest fruit quality in strawberries.

This Practical Farmers of Iowa research brief details a 2025 on-farm trial across four Iowa farms testing corn gluten meal as an organic pre-emergent weed suppressant in onions, cabbage, and lettuce. It outlines trial methods, weed biomass and crop yield results compared to mulching/cultivation controls, and farmer takeaways on corn gluten's practical limits and fertilizer value.

In 2017, a participatory action research team from the University of Vermont initiated a study to identify the underlying causes of the annual food insecurity faced by families belonging to an organic coffee cooperative. The research reveal…

Culling, the selective removal of specific individuals within a herd, is a common management practice within the dairy industry and can be important for maintaining healthy herds. This study, led by researchers from Texas A&M University and Colorado State University, analyzed data from U.S. organic dairy farms to better understand how, when, and why cows are culled.

This Practical Farmers of Iowa research brief describes a 2025 on-farm trial by four Iowa organic farmers testing BioGuard (an OMRI-listed biological seed coating advertised to reduce insect feeding and fungal disease) in corn. It outlines trial design, methods for measuring plant population and yield, and results.
