Solarización y biosolarización: aprovechamiento del sol y la materia orgánica para controlar las malas hierbas

Biosolarization is an innovation in the realm of weed control. 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. This presentation covers theoretical concepts as well as results from field trials.
