Martin Resources manufactures and markets ammonium sulfate (AMS) products at our Plainview, Texas facility. Martin Resources is also one of the few U.S. manufacturers that produce “Made On Purpose” Ammonium Sulfate using Anhydrous Ammonia and Sulfuric Acid (Virgin) as opposed to AMS that is a by-product from Caprolactam (Fiber) production. The majority of AMS produced and imported into the U.S. is from Caprolactam production. Martin’s Agricultural AMS grades (Granular, Coarse and Standard) are marketed throughout the major crop-producing states. Martin Resources also markets spray grade ammonium sulfate in 51# bags under the trade name ZippSol. ZippSol is mixed in a solution with herbicides (glyphosate, etc.) for field application. 40% Ammonium Sulfate Solution is produced along with the dry AMS at the Plainview, TX facility and can be used in spray solutions for agriculture and some industrial applications.
