A machine that uses steam to disinfect the soil with excellent results is finally available. It is semi-moving, suitable for both protected crops and open fields and works in all cases where soil fatigue must be eliminated or prevented. The steam deactivates nematodes, fungi and weed seeds with an entirely organic principle. Biovap uses steam without needing chemical principles. Marco Scotta from Carmagnola developed this solution and owns the patent. This soil sterilization machine is mounted on a radio-controlled crawler truck that features a stone burier. There are two models available: the larger has a 1000 kg/hour vapor generator, while the smaller has a 650 kg/hour generator. The steam is injected into the soil at a depth of 20-25 cm. A film is immediately placed to cover the sterilized surface so as to make the treatment more effective. Source - https://www.freshplaza.com
