METHOD OF CONSTRUCTING A GROUND FOR TREE-PLANTING WITH THE DREDGED SOIL OF RECLAIMED LAND FROM THE SEA, CAPABLE OF IMPROVING SOIL POROSITY AND AIR PERMEABILITY BY SIMULTANEOUSLY CONSIDERING THE DRAINAGE, PERMEABILITY, SALINITY, pH, AND NUTRIENTS OF SOIL

摘要

PURPOSE: A method of constructing a ground for tree-planting can reform the dredged soil of reclaimed land in a reduction condition to the soil for tree-planting capable of normally growing plants by quickly control the soil electrical potential and chemically reform soil with excess salts.;CONSTITUTION: A soil potential-controlling composition includes 0.1-4.5 % of a soil oxygen supplying composition, 0.1-3.5 % of an oxidation accelerator, 0.2-5.0 % of a potential buffering agent, 0.005-1.0 % of a surfactant, and residual water. A method of constructing a ground for tree-planting includes a step of controlling soil potential to 220 mV or greater; a step of desalinizing the soil by mixing the soil with salt-removing composition; and a step of mixing a soil-weight-reducing composition. The salt-removing composition consists of 45-83 wt% of calcium sulfate, 5-25 wt% of calcium carbonate, 5-25 wt% of magnesium carbonate, 5-25 wt% of magnesium carbonate, 5-20 wt% of calcium sulfate, and 2-5 wt% of iron sulfate.;COPYRIGHT KIPO 2013
