With the positive results from S fertilization in alfalfa (see related article, page 6), trials were started in 2006 corn fields where early plant growth was exhibiting S deficiency symptoms or where there was expectation of S deficiency. Calcium sulfate (CaSO4•H2O, gypsum) was surface broadcast applied after early corn growth at 40 lb S/A, with a control treatment for comparison. The 40 lb S/A rate was chosen as a non-limiting S rate to maximize any potential yield increase.
