PROBLEM TO BE SOLVED: To provide a method for producing a culture soil raw material in which mixing with a culture soil main material is favorably carried out and culture soil having always definite quality can be obtained. SOLUTION: In the method for producing the culture soil raw material, mixed in a definite ratio with the culture soil main material and used for giving nutrient ingredients to plants, liquid fertilizer containing desired nutrient ingredients is absorbed into a support having the nearly same specific gravity as the culture soil main material and the support containing the liquid fertilizer is dried to provide the culture soil raw material. In the production method, it is particularly preferable that a plurality of culture soil raw materials A to E obtained by absorbing liquid fertilizers having mutually different nutrient ingredients to the support are prepared and these raw materials are arbitrarily and selectively mixed to provide desired culture soil.
