There are numerous applications for soil heating. Thawing soil prior to excavation, chemical decontamination, land mine clearance and soil sterilization are just a few potential uses. Microwave heating has been applied to various agricultural problems since the 1960s. In particular, treatment of soils as a method of weed and pathogen control has been proposed for some time. In Europe, microwave heating is already being proposed as an alternative to soil fumigants. This paper present microwave device for soil heating specifically used forest nursery soil treatment. The measurements ofheating rates were performed for two soil moisture levels: 10 percent and 40 percent. The soil was heated by 700 W power microwave device and 2.45 GHz frequency was used in the experiments.
