Abstract:
     The present invention relates to a new-type high-efficiency phosphatic fertilizer protecting inorganic salts by using organic acid. It is characterized by its raw materials mixing method, and taking 100 kg as example to make further detail description: a.38kg of sulphuric acid whose concentration is 70% and 6kg of animal waste hide and hair are mixed, stirred and dissolved into 44 kg of liquid mixture, and then the above-mentioned mixture is mixed with organic acid, and 61 kg of phosphorus ore powder whose phosphoric content is above 24% is added, and then the above-mentioned materials are passed through the processes of stacking, curing and drying, and made into 100kg of the new-type high-efficiency phosphatic fertilizer containing 9.2% of water and 13% of effective phosphorus; C. 38 kg of sulfuric acid and 10 kg of distiller's grains or vinegary grains are mixed, and other procedures are identical to the above-mentioned procedures in "a".
