  • Patent number: 10865158
    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.

  • Patent number: 10766828
    Abstract: Stable, liquid fertilizer compositions comprising nickel, cobalt, and molybdenum are provided herein. The fertilizer compositions are capable supplying high levels of micronutrients to seeds at low doses of the compositions. The compositions generally have low salinity and a pH from about 6.0 to about 8.0, thereby avoiding the high mortality rates of beneficial soil bacteria, which has been a major problem with prior seed fertilizers. Also provided herein are methods of forming and using the fertilizer compositions. Notably, it has been discovered that monoethanolamine molybdate solutions can be used to provide high levels of molybdenum to seed surfaces in a stable liquid formulation.
