Northeast Research and Demonstration Farm
Grain producers in northeast Iowa are interested in the effects of liming rates on crops and soils. Currently, it is recommended that a corn-soybean rotation requires a soil pH of 6.5. This experiment was designed to determine the effects of liming rate on soil pH and a corn-soybean rotation that is under-, adequately, and over-limed according to this recommendation.
