Abstract: A movable type of device for fertilizing the soil by piercing a nozzle into the same comprises a moving support which is adapted to lift, retain and move a device for fertilizing the soil by piercing a nozzle into the same. This device comprises a nozzle for injecting a specified amount of fertilizer from its tip end portion into the soil by use of a blast of air, a nozzle striking hammer for applying an impact force to the nozzle to drive the same into the soil, a nozzle drawing-out for drawing the pierced nozzle out of the soil, a blast source for causing a blast of air to be produced, and a fertilizer metering chamber for metering the fertilizer. The fertilizer metering chamber indludes a fertilizer holding chamber which is arranged to temporarily hold therein the specified amount of fertilizer supplied from a fertilizer storage chamber. The fertilizer is suitably fed into a passage of the device for being injected into the soil from the tip end portion of the nozzle.
