Abstract:
     The production method of solid gas-ground composite fertilizer is characterized by that it uses the solid acids, such as danty whose humic acid content is above 30%, peat and plant ash or other humic solids to adsorb concentrated sulfuric acid or concentrated nitric acid to form sulfo-or nitro-humic acid solid acid containing free acid, then uses the obtained humic solid acid and ammonium hydrogen carbonate and trace elements of zinc and boron to synthesize the gas-ground composite fertilizer. Said invented solid gas-ground composite fertilizer integrates the CO2 gas fertilizer effect and ammonium humate ground fertilizer effect into one body, and is convenient for storage, transportation and use, and has no pollution to soil.
