PROBLEM TO BE SOLVED: To provide a mixed fertilizer which furnishes plants with fertilizer components necessary for each stage of the growth by applying the fertilizer at one time as a base fertilizer and thus does not require additional fertilization and a method of the fertilization.SOLUTION: The mixed fertilizer is obtained by mixing an uncoated fertilizer with not less than two kinds of coated fertilizers having fertilizing effects different from those of the uncoated fertilizer. In the fertilizer the guaranteed analysis of POis not less than 1.0 time that of N. Preferably, the not less than two kinds of coated fertilizers are the ones in which the elution of the contents is controlled for a certain period of time in the beginning and increased afterwards. Preferably, the uncoated fertilizer contains N, PO, and KO.【課題】元肥として一括して施用することにより、追肥を必要とせず、植物の生育の段階ごとに必要な肥料成分を植物に供給できる配合肥料及び施肥方法を提供すること。【解決手段】非被覆肥料と、肥効の異なる２種以上の被覆肥料とを配合する。そして、前記２種以上の被覆肥料における、Ｐ２Ｏ５の保証成分量をＮの保証成分量の１．０倍以上とする。ここで、前記２種以上の被覆肥料としてはいずれも、含有成分の溶出が初期の所定期間抑制され、その後高まるものであるのが好ましい。また、非被覆肥料としては、保証成分としてＮ，Ｐ２Ｏ５，Ｋ２Ｏを含むものであるのが好ましい。【選択図】図１
