Abstract
PURPOSE: To neutralize acid soil, to enable vegetation of wild lawn or the like, and to restrict corrosion of slope frames by forming layers of converter slag, acid soil, and calcium carbonate on a slope consisting of highly acid soil such as at an abandoned mine.
CONSTITUTION: With slope face frames 1 laid on a slope consisting of acid soil A, converter slag B of a grain size below about 10mm is laid in a thickness of about 3W10cm so as to bury the lower portions of the frames 1. Excavated acid soil C is laid on the slag B in a thickness of about 5W20cm as a middle layer. Calcium carbonate D is scattered on the middle layer in a thickness of about 0.1W2cm as a surface layer, which is consolidated so that it may mix with a portion of the acid soil C, followed by apraying of seeds of wild lawn or the like, sprinkling, and curing. The slag B contains not only nutriments but about 30W40% of calcium oxide, so that it neutralizes, together with calcium carbonate D, the acid soil A and C to obtain soil with pH about 5W8.
