PROBLEM TO BE SOLVED: To provide a soil conditioning machine capable of supplying a conditioning material by pushing and opening an operating plate by the movement of inputted residual soil and rotating a control valve formed integrally with the operating plate to open a conditioning material inlet. SOLUTION: This soil conditioning machine comprises a carrying tube body having a first supply port for sediment on the upstream side, a second supply port for the conditioning material on the downstream side adjacent to the first supply port, storing the sediment and the conditioning material supplied from the first and second supply ports, and carrying the conditioning material to an outlet formed at the tip thereof. The operating plate is formed integrally with a control valve opening and closing the second supply port. The operating plate is openably disposed at a position for closing a passage for the soil supplied from the first supply port and fed to the carrying tube body. When the sediment is moved in the passage, the operating plate is pushed open to displace the control valve so as to open the second supply port for supplying the conditioning material.
