Abstract

Novel granular fertilizers and methods of making those fertilizers are provided. The method utilized involves recycling streams, including one that provides water having dissolved solids therein, with that water being used during the mixing and granulation process. This method results in a low-moisture, hard, substantially spherical granule, which can include any number of macronutrients and/or micronutrients. Advantageously, the granular fertilizer can be applied to the soil around plants to supply those plants with the necessary nutrients.
