Abstract
We studied the effects of some materials of water-holding and mulching upon the action ofwater-holding in soil, evaporation control from earth surface and growth condition of plants (herb and trees).The experimental materials are five kinds, powder of soft ceramics and synthetic resin, barkcompost, and emulsion of synthetic resin and asphalt. Application water are three levels (Naclconcentration, p.p.m) of 0, 2, 5u0 and 5, 000.We wish to report on the results of our investigation which we have dealt with in ourlavatory and Hamaoka sea side.
