More Information
Summary:The present invention teaches novel compositions and techniques for economically producing highly concentrated nitrogen-sulfur suspension fertilizers using cheap and readily available by-product ammonium sulfate or by-product sulfuric acid and ammonia in conjunction with solid, liquid, or suspension nitrogen fertilizers and suspending clay. The products of the instant invention exhibit unique and very desirable physical properties and long-term storage characteristics not heretofore encountered in suspensions containing soluble fertilizer salts. Some of these unique characteristics include virtually no crystal growth during exceptionally long storage periods and near-constant or decreasing viscosity with decrease in temperature.
