<P>PROBLEM TO BE SOLVED: To provide coated granular fertilizer which, for example, can supply a fertilizer component suitable for survival after transplantation in a total amount manuring method in sowing seeds, and can be used for the seedbed composition of plant cultivation. <P>SOLUTION: The coated granular fertilizer takes ten days or longer until an accumulated elution rate of the fertilizer component reaches 3 wt.% in immersed in water at 25°C. In a graph drawn by plotting a vertical axis as a period component elution rate and a horizontal axis as an elapsed time, elution behavior has at least two points of peaks in the graph. <P>COPYRIGHT: (C)2012,JPO&INPIT |
