PROBLEM TO BE SOLVED: To provide a farming vehicle for spreading powder/granules which secures an amount of powder/granules spread per area highly accurately according to environmental conditions for spreading powder/granules without requiring experiential adjustment in the amount of powder/granules spread to spread the powder/granules. SOLUTION: The farming vehicle includes a powder/granule tank (11) for storing the powder/granules, and feed rollers (15, 15) capable of rotationally controlling the feed amount of the powder/granules from the powder/granule tank (11), and a powder/granule spreader (2) for spreading the powder/granules according to a travelling speed based on a set specific gravity of the powder/granules and a set amount of powder/granules spread per area. The powder/granule spreader (2) corrects a fluctuation in feed amount of powder granules due to a humidity during spreading based on actual measurement values in the amount of powder/granules fed from the powder/granule tank (11) by the feed rollers (15, 15), which are obtained beforehand according to environmental humidities, and rotationally controls the feed rollers (15, 15).
