Yara reported on Nov. 13 that its distribution agreement with American Plant Food Corp. (APF) for bulk standard ammonium sulfate at Yara’s dry facility in Stockton has come to an end. Yara said it will instead dedicate resources and warehouse space at Stockton to its recently introduced Amidas™ fertilizer, which the company describes as a 40-0-0 5.5 percent sulfur homogeneous fertilizer that combines urea and ammonium sulfate into one particle.
Yara said the 7.3:1 nitrogen to sulfur ratio in the product is optimal for grain crop fertilization, while ammonia volatilization is reduced by acidity formed from ammonium sulfate.
APF, which is headquartered in Galena Park, Texas, will continue to supply the California market with ammonium sulfate from its Woodland inventory.
