Weed management poses a significant challenge for organic producers. While several organic herbicides are available on the market, these can be expensive and may have a shorter residual activity than conventional herbicides. In this study, researchers established a series of field and greenhouse trials evaluating the efficacy of several commercial organic herbicides in apple production systems.

This final research report from OFRF and Kristin Swoszowski-Tran of Ledoux Grange details her farmer-led evaluation of teff accessions for lodging resistance and performance at high altitude.

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.

Living mulches offer potential for weed management in low or no till systems. In this episode of the Field, Lab, Earth Podcast, University of Wisconsin's Ben Brockmueller discusses cover crop management in corn as a means of weed suppression.

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…

Salmonella Enteritidis (SE) is a common type of bacteria found in raw poultry meat and eggs that can cause food poisoning in humans. SE can be transmitted directly from an infected hen to her eggs. In this study, researchers evaluated several organic-compliant eggshell surface treatments for SE management, including a peracetic acid (PAA) sanitizer and two probiotic treatments.

This final research report from OFRF and Markisha Parker of Parker Farm highlights farmer-led research conducted to compare mulch types on tomato production on an urban farm.

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.
