PURPOSE: A manufacturing method of an agent for improving soil quality and the agent for improving soil quality manufactured therefrom are provided to recover the fertility of soil by increasing the content of profitable organic compounds. CONSTITUTION: A manufacturing method of an agent for improving soil quality comprises the following steps: preparing raw material powder including a silicate system clay mineral, calcium, organic acid, and mineral sulfur(st11); granulating the raw material powder after adding moisture and drying(st13,st14); drying the granulated material at the high temperature over 200 deg C(st15); mixing the granulated material with a microbial agent and a liquid organic fertilizer(st16); and drying the mixture at the low temperature under 60 deg C(st17). The silicate system clay mineral is selected from the group consisting of zeolite, bentonite, kaolin, illite, biotite, sericite and feldspar. |
