This study found that cereal rye was effective at reducing total nitrogen and nitrate that leached from soil columns treated with both manure and urea, with no significant difference by fertilizer source. The cereal rye produced 20% more biomass when a surface application of urea was used instead of injected manure, however the cereal rye’s nitrogen uptake per acre was similar and phosphorous uptake was higher when manure was applied. No differences were found in soil nutrient levels regardless of cover crop status or fertilizer source. In terms of corn production cereal rye inhibited yields with both urea and manure as the nutrient source. There was no significant difference by nutrient source in terms of corm yield, however manure produced nominally higher yields. Overall, during the 2015-2016 season, there was no significant differences in how the manure and urea interacted with the cover crop.
