PROBLEM TO BE SOLVED : To provide a method for producing artificial humic soil regarding an artificial humic soil-mixed type greening construction method, enabling restoration of wasteland by spraying greening material stable in the long and medium terms over an objective land to be greened, and promoting humus by spraying the humic soil on the surface of the objective land using a spray machine. ŽSOLUTION : The method for producing artificial humic soil includes : infiltrating an organic material such as immature bark compost, sawdust, straw, chaff or dehydrated cake which contains about 70 wt.% of organic substances and whose humus does not proceed, with an extremely acidic solution having a mol concentration of 1.0-18.0 molL-1such as sulfuric acid solution, hydrochloride acid, or acetic acid for ≥5 hours, or with smoked powdery charcoal or coarse-grained smoked charcoal for about 100 hours. The bark compost as the immature organic material includes, for example, having a C/N ratio of ≤35, pH (H2O) 5.5-7.5, and an electric conductivity of ≤0.9 mS/cm. ŽCOPYRIGHT : (C)2010, JPO&INPIT Ž |
