摘要

A method for improving an ammonium-sulfate fertilizer material comprising feeding ammonium sulfate and liquid ammonium nitrate to a pelletizing pan, rotating said pan until pellets of a predetermined size are formed and separating from said pan the so-formed pellets of improved fertilizer material comprising ammonium sulfate and ammonium nitrate.
