BLACK LAYER REMOVAL METHOD FOR GRASS

摘要

PURPOSE: A black layer removal method for lawn grass for securing air permeability is provided to remove anaerobes by supplying oxygen to a black layer and top soil. CONSTITUTION: A black layer removal method for lawn grass for securing air permeability comprises the following steps: producing plural drain holes having a diameter of 5-6 cm and a depth of 40-50 cm on the surface of top soil with lawn grass(S100); filling the drain holes with functional soil containing an oxygen generating agent(S200); and spraying water on the surface of the top soil 1-4 times over 24 hours(S300). The functional soil contains 88-96.5 wt% of silica, 3-10 wt% of soil conditioner, and 0.5-2 wt% of an oxygen generating agent.
