The blended compost has the advantage of being practical in that the compost based on cattle feces is filled up with composts from swine or poultry manure thus, any imbalance in the amount of elements that comes from one is compensated by the other composts. In addition, composts formed small rods or pellets have reduced nitrogen mineralization at the rate of 30-50% than nonformed composts. It the summer cropping ( :sweet corn) when the soil temperature rises gradually, the design of application method for the blended and pelleted composts was considered useful based on nitrogen mineralization parameter as estimated by incubation tests. By combining 40 day-type released nitrogen fertilizer and readily available fertilizer, the applied amount of chemical nitrogen fertilizer could be reduced by 10-34% compared to the amount applied using the standard nitrogen fertilizer and also 100% requirement for phosphate and potassium fertilizer is not by the application of 0.5-1 ton( /10a) of compost. On the other hand, in the autumn cropping ( :cabbage) an increase in applied amount of readily available nitrogen fertilizer was necessary because the fertilizer absorption of cabbage was suppressed under the low soil temperature, resulting in the delay in early cabbage growth which also has a severe effect on yield
