Abstract
A high-quality and easy-to-handle artificial soil particle is provided which can exhibit well-balanced basic soil functions. In the artificial soil particle 10, a plurality of fillers 1 having a small hole 2 ranging from the subnanometer to the submicrometer scale are clustered together. A communication hole 3 ranging from the submicrometer to the submillimeter scale is formed between the fillers 1. The small holes 2 are distributed and arranged around the communication hole 3 so that the communication hole 3 is allowed to take in water W and nutrients K, N, and P from the outside and the small holes 2 are allowed to receive the nutrients K, N, and P from the communication hole 3. The fillers 1 are joined together into a three-dimensional network so that the total volume of the communication holes 3 is greater than the total volume of the small holes 2.
