We have produced compost pellets that incorporate an ammonium sulfate solution produced in Ammonia recycler device that collects the ammonia generated in the composting process of swine manure with sulfuric acid into the compost. The ratio between compost and ammonium sulfate of raw materials of these pellets is set at 100:21(proportion of dry matter). These pellets contained an available N, P, K at ratio of 4-8.5-3(wt.%). Although the initial amount of organic nitrogen formed from the fertilizer is greater due to being in pellet form, the nitrogen is quick-release since the main constituent of the nitrogen fertilizer is ammonia. The available nitrogen is approximately four times that of the raw compost. The phosphate fertilizer efficiency of these pellets is in no way inferior to that of chemical fertilizer. These pellets can be used as substitutions for chemical fertilizers in open field vegetable production or for fertilizer used in paddy rice production. They are also valuable as a fertilizer for their improved component balance and ease of distribution as well as for their incorporation of the collected volatile resources of the fertilizer.
