This is the sterilization method to inject high-temperature hot water into the soil. Injected hot water penetrates the soil and raises the soil temperature.
Pathogenic bacterias, harmful nematodes, harmful insects, weeds and seeds living in the soil are killed by the heat power.
Even at relatively low temperature, harmful microorganisms can be exterminated when they are exposed for a longer time.
Fusarium is said to be killed in one minute at 65℃, 8 hours at 50℃, and 48 hours at 45℃.
- Possible to raise the temperature to the deeper soil
- Effective to remove salts in salts-accumulated soil
