PROBLEM TO BE SOLVED: To provide an artificial soil particle that can maintain basic performance as soil even when external pressure and the like are received, the artificial soil particle having a good workability as well.SOLUTION: An artificial soil particle 10 is provided, comprising a base part composed of an aggregation of a plurality of fillers 1 having pores 2, at least the inside of the base part being reinforced with reinforcement material 5. The pores 2 have a size of from sub-nm order to sub-μm order, and communication holes 3 having a size of from sub-μm order to sub-mm order are formed among the fillers 1. The communication holes 3 take in water and nutrients from outside, and the pores 2 are dispersively arranged around the communication holes 3 so that the pores 2 can receive the nutrients from the communication holes 3.COPYRIGHT: (C)2014,JPO&INPIT【課題】外的な圧力等を受けても土壌としての基本性能を維持することができ、且つ作業性の良好な人工土壌粒子を提供する。【解決手段】細孔2を有するフィラー1が複数集合してなる基部を備え、基部の少なくとも内部が補強材5で補強されており、細孔2はサブnmオーダー乃至サブμmオーダーのサイズを有し、フィラー1の間にサブμmオーダー乃至サブmmオーダーの連通孔3が形成されており、連通孔3が外部から水分及び養分をとりこむとともに、細孔2が連通孔3から養分を受け取り可能なように、細孔2が連通孔3の周囲に分散配置されている人工土壌粒子10。【選択図】図1
