Abstract
Abstract An artificial ground system can be utilized in a green of a golf course or for ground unsuitable for cultivation. The artificial ground includes a collection layer having an inclined sheet member capable of collecting liquid agricultural chemicals or water, a soil supporting layer having a water-permeable soil supporting member disposed on the collection layer, and an artificial soil layer having artificial soil disposed on the soil supporting layer. For example, the artificial soil contains as a main component the remainder of fermentation material which is subjected to at least a controlled amount of water and combined with at least one or two additives required for soil constitution.
