NOVELTY - An organic fertilizer comprises (pbw): bone meal (5-20, preferably 10), hoof and horn meal (2-8, preferably 5), dung (30-50, preferably 40), shale (12-18, preferably 15), plant ash (8-12, preferably 10), humic acid (15-25, preferably 19.1), bacteria (0.7-0.9, preferably 0.8) and sugar (0.05-0.2, preferably 0.1).    USE - As fertilizer (claimed) used in medical appliance.    ADVANTAGE - The organic fertilizer improve the appearances of vegetable and fruit, improve the content of amino acid, reduce the amount of various agricultural pesticides, reduce the residues of harmful chemical substances e.g. the heavy metal, and the agricultural pesticide, achieve the harmless request, and is an agricultural production technology which is worth of popularization; provides better growth environment for plants; improves agricultural yield.    DETAILED DESCRIPTION - An organic fertilizer comprises (pbw): bone meal (5-20, preferably 10), hoof and horn meal (2-8, preferably 5), dung (30-50, preferably 40), shale (12-18, preferably 15), plant ash (8-12, preferably 10), humic acid (15-25, preferably 19.1), bacteria (0.7-0.9, preferably 0.8) and sugar (0.05-0.2, preferably 0.1). The bone meal is prepared by drying the bones of the livestock (preferably the bones of large livestock such as horse bones, pig bones and cow bones) in the air (drying naturally, such that the water content is low in effect for the final product, and can be ignored), and then crushing, where the diameter of the particle after crushing treatment is 1-8 mm. The hoof and horn meal is prepared by using hoof tips which are hoofs of horse, sheep and donkey, and horns of cow and sheep (preferably cow hoofs, cow horns, sheep hoofs and sheep horns), cleaning, performing disinfection at high temperature and high pressure (the stewing condition is preferably as follows: having 5 pressures at 140 degrees C), drying in the air, performing crushing treatment, where the diameter of the processed particle is 1-8 mm where the weight ratio of hoof powder to the horn powder is 1:3. The treatment of the dung (the dung is selected from various livestock, preferably chicken manure) is as follows: the water content is 15%; and the crushing degree is 100 meshes. The shale needs to be crushed, where the particle size is 1-200 mm. The bacteria is Japan biological enzyme bacteria. The fermentation conditions of the Japan biological enzyme bacteria are as follows: the fermentation temperature is 45-70 degrees C; and the fermentation time is one week to two weeks. An INDEPENDENT CLAIM is included for preparing the fertilizer involving: mixing hoof and horn meal, chicken manure, shale, plant ash, humic acid, bacteria and sugar according to the proportion, performing fermentation for one week to two weeks at 45-70 degrees C till discovering white slide net shape generated by fermentation, drying in the air, crushing and forming the particles, where the water content is 10-15%.
