1. A fertilizer product comprising a plurality of granules coated for moisture control, each of the coated granules comprising:
a base fertilizer granule; and
a moisture control coating applied to the base fertilizer granule, the coating including a hydrophobic material component and a roughening component,
wherein the roughening component comprises particulates having a particle size in a range of from about 10 μm to about 150 μm so as to form a micron-scaled surface roughness on an outermost surface of the coated granules,
wherein the hydrophobic material component comprises an oil selected from a group consisting of a mineral white oil, petroleum oil, canola oil, sunflower oil, soy oil, castor oil, linseed oil, olive oil, modified vegetable oils, and combinations thereof, and wherein the hydrophobic material is present in an amount of from about 0.5 to about 2.0 weight percent of the entire fertilizer granule.

8. A method of providing a moisture control treatment to fertilizer granules, the method comprising:
providing a plurality of fertilizer granules; and
coating the fertilizer granules with a moisture control treatment material comprising a hydrophobic material and a roughening component, wherein the roughening component comprises particulates having a particle size in a range of from about 10 μm to about 150 μm so as to form a micron-scaled surface roughness on an outermost surface of the coated granules, wherein the hydrophobic material component comprises an oil selected from a group consisting of a mineral white oil, petroleum oil, canola oil, sunflower oil, soy oil, castor oil, linseed oil, olive oil, modified vegetable oils, and combinations thereof, and wherein the hydrophobic material is present in an amount of from about 0.5 to about 2.0 weight percent of the entire fertilizer granule.

16. A fertilizer product comprising a plurality of granules coated for moisture control, each of the coated granules comprising:
a base fertilizer granule; and
a moisture control coating applied to the base fertilizer granule, the coating including a hydrophobic material component and a roughening component, wherein the hydrophobic material is present in an amount of from about 0.5 to about 2.0 weight percent of the entire fertilizer granule,
wherein the roughening component comprises particulates having a particle size in a range of from about 10 μm to about 150 μm so as to form a micron-scaled surface roughness on an outermost surface of the coated granules, and
wherein the roughening component is present in an amount of from about 0.01 to about 10 weight percent of the fertilizer granules.
