<P>PROBLEM TO BE SOLVED: To provide a service vehicle having a fertilizing device of performing proper fertilization with neither an excess nor poor amount of a fertilizer and depending on the firm field, and capable of evening the fertilizer concentration all over the firm field. <P>SOLUTION: The service vehicle equipped with a seedling planting device 4 is configured to include: an adjusting motor 6 for driving a fertilization amount baffle 41 to adjust the fertilization amount; a rotation shaft 7 rotated by the adjusting motor 6; an indication needle 9 moving in the axial direction by rotation of the rotation shaft 7; a stroke sensor 14 detecting the moving amount of the indication needle 9; a fertilizer concentration sensor 71 detecting the fertilizer concentration in the soil while travelling; a standard fertilization amount calculating part calculating the standard fertilization amount based on the detected value detected with the sensor 71; and an adjustment fertilization amount calculating part calculating the adjustment fertilization amount of the baffle 41 based on the detected value detected with the stroke sensor 14. The vehicle further includes a fertilizing device 5 having a control device 72 driving the adjusting motor 6 to correspond the fertilizing amount calculated by the adjustment fertilization amount calculating part to the fertilization amount calculated by the standard fertilization amount calculating part and, when the fertilization amounts of the both calculating parts are corresponded, stopping the adjusting motor 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
