Abstract
Granular fertilizers for efficient plant uptake of nutrients and delayed release of fertilizer compounds. A composition includes a granular fertilizer and a wetting agent configured to reduce a surface tension of water. The composition optionally additionally includes an ion exchange nanoparticle, wherein the ion exchange nanoparticle comprises a structural particle comprising an ion exchange site and an ion, wherein the ion is attracted to the structural particle at the ion exchange site.

A composition comprising:
- a granular fertilizer;
- and
- a coating disposed around the granular fertilizer, wherein the coating comprises:
- a first polymer that is water soluble;
- a second polymer comprising a copolymer;
- and
- a wetting agent configured to reduce a surface tension of water;
- and
- an ion exchange nanoparticle that comprises:
- a structural particle comprising an ion exchange site;
- and
- an ion, wherein the ion is attracted to the structural particle at the ion exchange site;
- wherein a coating solution comprising each of the first polymer, the second polymer, and the wetting agent is mixed with the granular fertilizer.
