Field Evaluation of Designed Compost Extracts for Organic Weed Suppression

Dr. Gladis Zinati, Rodale Institute

In 2013-2014, OFRF funded Dr. Zinati to perform laboratory and greenhouse trials on the weed suppressing ability of chemically- and biologically-designed compost extracts (DCE). This new project builds off of the laboratory and greenhouse work to test the DCEs in the field and evaluate them as an alternative tactic to reduce weed pressure, soil degradation, and yield losses of field-grown organic cabbage.

Impact: Reduced weed pressure, soil degradation, and yield loss.
