Technical Abstract: Field experiments were established on 2011 simultaneously at Shorter in east-central Alabama; Farmland in east-central Indiana; Hoytville in northwest Ohio; and Piketon in southern Ohio. A factorial experiment (3 FGD-gypsum rates x 3 cropping diversity x 2 cover crops) in randomized complete block design with four replications was established at all locations. The FGD-gypsum rates were 0 (control), 1000 and 2000 kg/ha, respectively, which were broadcasted. The cropping diversity included continuous soybean, soybean-corn, and corn-soybean rotations with- and without cereal rye as a cover crop. Each replicated plot was 10-m long by 7-m wide with a 1-m buffer between plots. Cereal rye @ 60 kg/ha was drilled after harvesting corn or soybeans followed by chemical termination in mid-April and planting of corn or soybeans in the 2nd week of May. All the plots received the same standardized cultural practices such as chemical fertilizers and herbicides annually for their respective crops. While 150-100-100 kg N-P-K/ha was applied for corn, 0-100-100 N-P-K/ha was applied for soybeans. The experiment was repeated until 2016.
