3 farmers began
At the end of the 1990s, 3 farmers began to experiment with steam as an alternative to chemicals to clean the soil for weeds, fungi and nematodes. The first machine was completed in 1996. It was difficult to use, primitive and not very effective.
The machine documented what the 3 farmers had hoped for; they could document that their method killed all harmful organisms in the soil only by means of water vapor. No one had done this before.
