What incremental yield response can I expect from fertilizing with sulfate versus bagged or elemental sulfur?


The yield response differential for any given crop will depend on a variety of soil and environmental factors.  In university trials, sulfate has been found to outyield elemental sulfur by about five bushels per acre on corn and wheat studies. On forage, a four-year alfalfa study clearly showed that elemental sulfur did not become available quickly enough to make a difference in the year of application, translating into an advantage of a half of a ton with ammonium sulfate when compared to elemental sulfur.
