Biofumigation favors the sustainability of the soil by first cleaning the pathogens and then preserving the microorganisms that favor plant health. It should not be used alone but should be accompanied by several practices both at the beginning (wetting and drying of the soil) and after disinfection (mulching) to achieve a balance of soil flora and fauna.
