The invention relates to an organic total nutrient fertilization method, which has the advantages of improving utilization efficiencies of various elements, improving effectiveness of mineral nutrients, enhancing resistance of crops, increasing the number of useful microorganisms in soil, enhancing activity of the microorganisms, improving soil structure, and improving soil fertility. In the method, 40 to 120 kilograms of active humic acid, 30 to 80 kilograms of formula fertilizer and 10 to 20 kilograms of chelated compound micro-fertilizer are mixed and then applied on each mu of land. The activation process of the active humic acid comprises: sorting natural organic substances, removing impurities, grinding the natural substances, degrading and inactivating the ground natural organic substances in a reaction kettle, blasting the product of the degradation and inactivation under a reduced pressure, condensing the product and obtaining the finished product, wherein the temperature is between 80 and 175 DEG C, the pressure is 3 to 12.5 atmospheric pressures, the light wave is 364 to 468cm-1 ultraviolet light, the hydrolytic reagent KOH is 2.5 to 20 weight percent, the oxidant TiO2 is 3 to 12.5 weight percent, and the guiding agent FeSO4 is 0.3 to 3 weight percent.
