The invention discloses a hydrosulphate soil amendment and a preparation method thereof. In the invention, 30-67 parts of acid change substances, 30-67 parts of phosphorous-containing substances and 2-5 parts of microelement substances are adopted for the preparation of the hydrosulphate soil amendment; when the acid in the hydrosulphate soil is neutralized better, the effective phosphorus content of the soil can be increased obviously; due to the neutralization action to soil acidity, the fixation of effective phosphorus by the ions of aluminum, ferrum and manganese can be effectively released, so that the content of the effective phosphorus in the hydrosulphate soil is further improved; and moreover, scarcer nutritive elements such as magnesium, zinc and boron in the hydrosulphate soil can be supplemented, thus being beneficial to the improvement of soil nutrient conditions; in such a way, the growing of various crops planted in the hydrosulphate soil is improved; and therefore, the problem ...
