Abstract

Liquid swine manure was applied as a post-emergent sidedress source of nitrogen and compared to 28% Urea Ammonium Nitrate (UAN) in on-farm corn plots in Ohio at 15 sites over three crop seasons. The manure was applied using a 5,250 gallon manure tanker, modified to travel down corn rows, and Dietrich incorporation sweeps. The 28%UAN was incorporated using standard sidedressing equipment. The incorporated manure treatments resulted in a statistically similar corn yields compared to the commercial fertilizer treatments in nearly all the plots. Livestock producers with liquid manure can better capture the nitrogen in the manure by applying it to a growing crop at a time when the crop can utilize the nutrient. Livestock producers could also potentially save money by not purchasing nitrogen to sidedress the corn crop.
