Dried Granular Monohydrate

General Information

The dried Monohydrate form of Ferrous Sulfate contains the greatest amount of Iron per ton (~30%) and the least amount of interior water (one molecule or ~12% by weight). Granular Ferrous Sulfate Monohydrate is primarily used as a fertilizer ingredient for Turf, Ornamental, and Agricultural applications.  At QC Corporation, the Granular Monohydrate is available in two sizes, Fine Granular (US Sieve Mesh Size of -16 +30, sgn 100) and Coarse Granular (US Sieve Mesh Size of -6 +16, sgn 230).  As the ONLY domestic producer of Granular Ferrous Sulfate Monohydrate in North America, we wax coat and double screen our product for dust control after our proprietary curing process.  This allows us to offer a harder de-dusted granule that is ideal for bulk blenders who strive for premium quality.

Both sizes of Granular Ferrous Sulfate Monohydrate will not compact or cake in transit or in storage as long as it is not exposed to free water or temperatures in excess of 325° Fahrenheit.  In addition, the higher Iron content of Monohydrate results in lower transportation, bagging and palletizing costs per pound of Iron by as much as 33% when compared to the same costs per pound of Iron contained in Moist and dried Ferrous Sulfate Heptahydrate.
