PROBLEM TO BE SOLVED: To provide a soil conditioner which has a fast-acting property, does not damage the roots of plants, and enables the sowing of seeds from the day when the soil conditioner is scattered. SOLUTION: The method for producing the marine resource-using soil conditioner 3 comprises a calcination treatment process P1 for calcining a marine resource 1 containing calcium carbonate and organic substrates surrounding the calcium carbonate as main constituents in calcination conditions for changing the organic substrates into such an extent as enabling the separation of the calcium carbonate from the organic substrates and a pulverization treatment process P2 for separating the calcium carbonate from the calcination treatment product obtained in the calcination treatment process P1.
