Claim:
1. A process for preparing dry humic-mineral agent granules, the process comprising: providing a humic acid-containing material; crushing the humic acid-containing material to obtain first granules; contacting a quantity of water sufficient to prevent dust formation with the first granules, so as to form slightly wet granules; blending the slightly wet granules for a period of time, thereby forming blended granules; contacting an amount of alkali with the blended granules, thereby forming alkali-treated granules; and mixing the alkali-treated granules at a temperature high enough to melt organic carbon substances in the alkali-treated granules and evaporate excess water, thereby forming dry humic-mineral agent granules.
