PROBLEM TO BE SOLVED: To provide a peat-moss inserted burnt soil which is difficult to be deformed in shape, in which peat-mosses are difficult to flow out and to be unevenly distributed even without using an adhesive, which is high in ventilation, water retention, and nutriment retention, and which provides a plant growth promotion effect.SOLUTION: An raw material clay is mixed with peat-mosses to be made peat-moss inserted aggregate clay. The peat-moss inserted aggregate clay is granulated and dried by a granulation drying device(rotary kiln) 2 to be made peat-moss inserted granular soils. A part of SiOincluded in the raw material clay is vitrificated, the peat-mosses are sealed inside the peat-moss inserted granular soils, and the peat-moss inserted granular soils particle-adjusted by a particle adjusting machine 5 are sieved to be sorted out by sizes.SELECTED DRAWING: Figure 1【課題】形崩れにくく、接着剤を使用しなくとも、ピートモスが流出、分離偏在しにくく、通気性、保水性、保肥力に優れ、植物育成促進効果のあるピートモス入り焼土を提供する。【解決手段】原料粘土にピートモスを混合してピートモス入り団粒土にし、そのピートモス入り団粒土を造粒・乾燥装置（ロータリーキルン）２で造粒・乾燥してピートモス入り粒状土にするとともに、原料粘土に含まれるＳｉＯ２の一部をガラス化させて、前記ピートモスを前記ピートモス入り粒状土の内部に封入し、調粒機５で調粒したピートモス入り調粒土を篩にかけてサイズ別に選別する。【選択図】図１
