Abstract
A subsoil structure for sodded ground comprising a water-retaining layer filling a pan-like cavity, a sand layer covering the water-retaining layer, and a soil-improving layer covering the sand layer and incorporating a soil-improving material which is of a porous structure. Since the soil-improving layer has a good water-retentivity and the water-retaining layer is provided for retaining or storing water, the number of watering times can be extremely reduced, thereby saving time and labor for watering.
Claims5
