Download or read book Effect of Stay N Nitrification Inhibitor Upon Corn Yield and N uptake on Iowa Soils written by Kyle Gustav Jensen and published by . This book was released on 2003 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen fertilization is necessary to obtain respectable corn yields. Loss of nitrogen applied to the soil can significantly decrease yields. Suppressing the rate of nitrogen oxidation into a form that can be leached from the root zone may increase N use efficiency. The use of a nitrification inhibitor (nitrapyrin) has been shown to protect crop yield and groundwater quality when leaching conditions exist. Two year studies were conducted to determine the efficacy of reformulated nitrapyrin (Stay-N) when used with urea-ammonium nitrate solutions (liquid N fertilizer) and liquid swine manure upon corn yields. The liquid N studies were conducted in 2000 and 2001 at the Northwest Iowa Research Farm on a Galva soil (Typic Hapludoll) and in Central Iowa at the Burkey Farm on a Nicollet soil (Aquic Hapludoll). Treatments were arranged in split-plot, randomized, complete block design replicated four times. Main plots were Stay-N treatments, with (0.56 kg ai ha−1) or without Stay-N. Sub-plots were seven different rates of nitrogen: 0, 45, 90, 135, 180, 225, and 270 kg ha−1. Stay-N was mixed with the urea-ammonium nitrate solutions and sprayed on the appropriate plots using a small plot fertilizer applicator. The liquid swine manure study was conducted in 2001 and 2002 at the Armstrong Research Farm near Lewis, Iowa on a Colo soil (Cumulic Endoaquoll). The study was arranged in a randomized complete block design replicated four times. Liquid swine manure was applied to the plots to supply 0, 90, and 179 kg ha−1 of nitrogen. Stay-N rates were 0, 0.56, 1.12, and 2.24 kg ai ha−1. Stay-N was mixed with the swine manure before treatments were injected into the soil. Environmental conditions did not favor N losses during the time the studies were conducted.
