PROBLEM TO BE SOLVED: To make it possible to be able to perform a gentle to people and healthy crop cultivation even if pathogenic bacteria, seeds of weeds, noxious insects, roots of weeds, etc. which are archfiends to the crops, are remaining in a soil for cultivation, by digging out the soil, crushing the soil into small aggregates and calcining with a fire power to terminate them without using a chemical for making a fertile soil capable of performing a continued cultivation. SOLUTION: This soil calcining device has a constitution of installing a plowing tool 16 for plowing a soil at its frame, transporting the plowed soil with a conveyer 13, finely crushing the soil with a rotary rotor 12 at the conveyed position, calcining the soil on each discs of upper, middle and lower 8, 8, 10 becoming one unit with a fire burning cylinder 4 successively from the upper disc by a fire heat generated from the lower part of a fire burning cylinder and returning the completely calcinated soil to an originally plowed position i.e. a plowed groove part. |
