SOIL MODIFIER COMPRISING BOTTOM ASH AND MINERAL MATERIAL COMPRISING ILLITE RADIATING FAR INFRARED RAY, AND ITS PREPARATION METHOD

摘要

PURPOSE: Provided are a soil modifier which uses bottom ash and a mineral material radiating a far infrared ray, reduces the acidity of soil and improves air permeation and water conservation, and its preparation method. CONSTITUTION: The method comprises the steps of screening bottom ash suitable for the condition of a soil modifier, and washing and drying it; pulverizing the dried bottom ash to obtain a fine particle; screening a mineral material suitable for the condition of a soil modifier, and washing and drying it; pulverizing the dried mineral material to obtain a fine particle; and mixing the bottom ash powder and the mineral material powder in a ratio satisfying the composition standard of an inorganic fertilizer. Preferably the mineral material comprises fly ash and illite in a ratio of 75:25 by weight.
