The first step in soil solarization is to till the area to be treated. It is necessary to break up soil clods and plant debris in order to enhance heat conduction through the soil. (University of Arizona)

In addition, solarization stimulates the release of nutrients from organic matter present in the soil. It is especially effective for treating garden soils, where the intent is to plant vegetables, herbs, and flowers. (weekendgardener.net)

Solar energy can be used to kill weeds, weed seeds, and pathogens in garden and restoration sites. Solarization is often as effective as herbicides, fumigants, and other hazardous and expensive pest control methods (ecocomposite.org)
