Demands for quality, health, and environment are also issues guaranteed by the European normative in environmental matters with this normative in environmental matters with this normative becoming increasingly far reaching and strict. Crop intensification and repetition lead to soil degradation and increased resistance of pathogens like Verti-cillium,Phytophthora, or nematodes, making soil disinfection essential. In recent decades, the most common method used to disinfect soils for vegetable growing has been the use of methyl bromide (MB). Nevertheless, the risks it poses to the environment have generated great deliberation and, after long debate, the Montreal Protocol was signed in 1987 with the decision to ban general use after 2005. An alternative to MB is soilless cropping systems, which appear to be a safer and more decisive alternative for for the producer (Engindeniz,2004)
