<p>The present invention relates to a soil conditioner composition using fly ash and a manufacturing method thereof. Fly ash comprises inorganic matters, has similar properties to soil, and contains nutrients such as P_2O_5, K, Ca, S, B, etc. necessary for plant growth, thereby having effects of increasing the soil fertility, and improving the pH of acidic soil. Accordingly, the soil conditioner composition containing fly ash of the present invention contains 51.2% of alkali powder and 49% of dissolved lime, which satisfies the waste lime standard of the official standard of commercial fertilizer. Also, the content of harmful heavy metals is detected at the optimum level or less, which is usable for an arable land. Furthermore, the soil conditioner of the present invention increases the crop yield, and is environmentally friendly as fly ash, a coal byproduct used to be reclaimed, can be recycled.</p> |
