Abstract
Recently, a new solarization method gained a great deal of attention thanks to various advantages in comparison with both the traditional one and soil fumigation (alternative soil treatment based on the use of chemical agents). This method implements traditional solarization by spraying a biodegradable black liquid over the soil surface before the application of a thermic film. This creates a thin black film that acts like a “black body”, significantly increasing soil temperatures at various depths. Thanks to higher temperatures, it is possible to eliminate most of the pathogens in shorter times compared to traditional solarization. In the present paper, the results of different trials carried out on green beans, Romanesco broccoli, and lettuce were reported. The aims of this work were to demonstrate the efficacy on soil borne pathogens, its lower impact on living soil fungal biodiversity and the agronomical performance of the new solarization method. All crops tested showed a significant yield increase when grown in soil treated with the innovative solarization method. Romanesco broccoli also exhibited improved inflorescence quality. Solarization had a positive impact on overall crop productivity: green beans showed a maximum yield increase of 165.3%, lettuce yields rose by 47.5%, and Romanesco broccoli yields were 111.5% higher compared to the non-solarized control. These results confirm that the new solarization method is more effective, as well as environmentally, economically, and socially sustainable compared to traditional methods.
