The use of low-pressure steam for soil disinfection in the vegetable-growing sector not only eliminates the need for chemicals but also accelerates growth during the early stages.
In fact, providing moisture deep into the soil and heat speeds up the germination or rooting process and enables the plant to grow more quickly.
The destruction of unwanted plant seeds by superheated steam, combined with the faster growth of cultivated plants, reduces the risk of weeds gaining the upper hand.
