The invention relates to a novel fertilizer and method wherein a complex humic acid fertilizer is formed a mix of a select organic material, water, and measured amounts of major inorganic elements of nitrogen, phosphate, potash and sulfur. The constituents mixed in a sealed reactor system with a first material, usually an acid, are hydrolyzed by a drastic pH change, raising the mix temperature and pressure, and the mix is subsequently blended with a second material of an opposite pH to the first material, usually a base, reacting with the mix to provide a further temperature and pressure increase, to alter the pH to that of the finished fertilizer, which humic acid fertilizer is then dried and granulated or liquefied to a pumpable slurry.
