Description

Fertilize during a dry year, especially with nitrogen, and you’ll burn up the crop! That’s a statement occasionally made by farmers in South Dakota. Research at SDSU, however, does not support this belief. Two examples of recent fertilizer research under very dry conditions are given in Table 1. Wheat in McPherson Co. and corn in Day Co. received nitrogen rates up to 125 and 150 lbs. per acre. Neither a yield increase of a yield decrease was measure at either location. Drought at both locations limited yields to about 20 bushels wheat and 40 bushels corn per acre.
