PURPOSE: A manufacturing method of a block for protecting grass and a block thereby are provided to supply nutrients to planted grass and to protect the planted grass from vehicles. CONSTITUTION: A manufacturing method of a block for protecting grass is as follows. Pulverized rubble passes through a filter screen and is sorted(S1). The sorted rubble is mixed with water, cement, a mixture, sand, activated charcoal, and zeolite(S2). The mixed base compound is mixed with nutrients(S3). A surface layer compound is prepared by mixing the sorted rubble with water, cement, a mixture, sand, jade rubble, and glass beads(S4). A bottom portion of a mold is filled with the base compound, and the residual portion of the mold is filled with the surface layer compound. The base compound and the surface layer compound are pressed and integrated(S5). The mold is separated from the molded article(S6). The molded article is cured using steam heat(S7).
