Abstract
In order to study the residual effects of the subsoiling in areas where the tree growth is restraint by a hardpan or clay layers with impeded drainage, pits were opened in three typical forest soils, where subsoiling has been used to increase the effective depth. The study carried out shows that the residual effects are large enough to allow the roots penetrate into the subsoil before the layer becomes hard again. Moreover the obvious change of the soil density favours the water retention. It is recommended the subsoiling of the areas where technicaiiy and economically is possible to increase the effective soil depth.
