An organic fertilizer spreading machine was developed in Taoyuan DAIS by attaching the spreading mechanism to a small tractor. A big tank installed to the spreading machine could load 0.4 cubic meters organic fertilizer. The spreading machine provided three functions; 1. Spreading organic fertilizer from two sides, which was favorable for watermelon etc. 2. Spreading organic fertilizer from middle hole, which was favorable for vegetable. 3. Spreading organic fertilizer from whole band, which was favorable for pre-cultivation application. The results of the experiments indicated that this spreading machine was not only useful for spreading organic fertilizer, but also for spreading lime. It is worth to recommend the spreading machine to the farmers.
