Biosolarization: Sustainable Weed Control

(Parts of this video were shot under windy conditions. We suggest turning on the Closed Captions option while viewing it.) In this video, National Center for Appropriate Technology Sustainable Agriculture Specialist Martin Guerena discusses biosolarization, a new, innovative, and sustainable weed-control method. Different from the commonly known practice of solarization, which uses clear plastic sheeting on moist soil to thermally terminate a variety of pest species, biosolarization includes the use of organic matter in the form of compost, cover crops, manure or other materials such as pomace or nut hulls. The addition of organic matter can accelerate the process by encouraging anaerobic soil disinfestation. The carbon from organic material produces chemicals with bio-pesticidal activity. The combination of these natural chemicals and heat acts like a fumigant and eliminates soil-borne pests and weed species.
