The invention relates to fertilizer, in particular to a method for preparing organic fertilizer by mixing livestock excrement and humic acid. The invention aims at providing the method for preparing the organic fertilizer by taking the livestock excrement as a raw material and mixing the livestock excrement and humic acid. The method is simple, and the production cost is low. The method adopting the technical scheme that the method comprises the steps of mixing 5-6 parts by weight of livestock excrement, 4-5 parts by weight of powdered humic acid, and 1-2 parts by weight of urea, adding 10-20kg biological culture, stirring uniformly, grinding a mixed material, stacking the ground material into a pile, evaporating water from the ground material and raising the temperature by fermentation, turning over the pile when the temperature rises to 45-50 DEG C, and then preparing the granular biological organic fertilizer through granulation and screening. The method is mainly used for preparing the organic fertilizer.
