PROMOTER FOR LAWN GLASS GROWTH AND ORGANIC SUBSTANCE DECOMPOSITION CAPABLE OF PROMOTING DECOMPOSITION OF UNDECOMPOUND ORGANIC SUBSTANCE WHILE PROMOTING GROWTH OF LAWN GRASS IN LAWN AND METHOD THEREFOR

摘要

PURPOSE: To provide a method for promoting the decomposition of undecomposed organic substances such as cut wastes of lawn grass accumulated on the lawn surface in clipping and killed stems and leaves and roots while promoting the lawn growth in the lawn. CONSTITUTION: The characteristic of this method for promoting the decomposition of organic substances while promoting the lawn growth in lawn comprises mixing a granulated slag formed as a by-product from a cupola furnace in producing cast iron with pyroligneous acid which is a by-product formed in dry distillation of wood at a weight ratio within the range of (99:1) to (50:50) and sprinkling the resultant mixture on the surface of lawn. Furthermore, the characteristic of this promoter comprises the mixture of the granulated slag with the pyroligneous acid at the weight ratio within the range of (99:1) to (50:50).
