The invention provides an accurate ratio method for improving acidified soil through lime matter and organic fertilizers. The accurate ratio method comprises the steps: (1) respectively calculating the calcium carbonate equivalent of general lime matter and the calcium carbonate equivalent of general organic fertilizers; (2) testing a pH value, cation exchange capacity and base saturation percentage of soil to be improved and calculating the lime application amount according to the pH value, the cation exchange capacity and the base saturation percentage; (3) choosing and determining an appropriate match proportion of the organic fertilizers to the lime matter; (4) determining specific kinds of the organic fertilizers to be used and the matter to be used and calculating out physical quantities required by a specific farmland of the organic fertilizers and the lime matter according to the equivalent weight of calcium carbonate corresponding to the specific kinds. An organic fertilizers and lime matter organic and inorganic compound type acidified soil improving agent prepared in the method disclosed by the invention not only can eliminate side effects of independently applying lime to the soil, further can achieve the purpose of stably and durably improving the acidified soil and has important application value in the aspect of soil acidification soil improvement.
