Abstract
A fertilizer composition including a base fertilizer granule with a hydrophobic or super-hydrophobic coating that reduces fertilizer caking and dust formation. The coating can include a roughening component, which creates micron-scale surface roughness, and a hydrophobic coating. Together, the components of the coating act to physically protect water soluble fertilizers granules from the ingress of moisture and from caking, and increase the resistance of the granules to abrasion.
