PURPOSE: A liquid fertilizer and a manufacturing method thereof are provided to encourage a growth of plants and to increase crops by using vermiculite, sericite and phosphorite appropriately. CONSTITUTION: The liquid fertilizer is a undiluted mineral solution obtained through acidifying and precipitation processes of a mixing material of powdered formed vermiculite of 55-65 weight%, sericite of 25-35 weight% and phosphorite of 5-15 weight%. The liquid fertilizer includes more materials selected among fertilizer elements selected from N,P or K, a Ge cleaner and pyroligneous liquid. The manufacturing method of the liquid fertilizer includes following steps. (i) The vermiculite of 55-65 weight%, the sericite of 25-35 weight% and the phosphorite of 5-15 weight% are shattered and mixed. The compound powder raw material is produced.(ii) The compound powder raw material is put into a sulphuric acid aqueous solution, and is stirred at a high temperature and acidized.(iii) The refined mineral solution is obtained after a precipitation process. |
