PROBLEM TO BE SOLVED: To provide a fertilizer spreader that can mix plural kinds of fertilizers in the hopper in a short time. SOLUTION: The agitation part is constituted with a U-shaped trough and a rotary shaft equipped with agitation blades set in the trough so that the raw materials are stirred and conveyed in one direction. A pair of the agitation parts are arranged adjacently so that the conveying direction of one agitation part may become mutually the sending direction of the other agitation part. At the terminals of these conveying directions, are set scrape-up tools so that the fertilizer may be scraped up to the adjacent trough whereby the raw materials are continuously circulated.
