Alberta Farmer Increases Yields With ESN
Ken Krywko of Sturgeon County, Alberta farms with his two sons Dan and …
Yields are means of three N rates, four replications, and two years. All products surface broadcast before planting at average N rate of 150 lbs N/acre. Net return calculations assume corn price of $3.50/bu, ESN price premium of $0.20/lb N over urea and $0.15/lb N over UAN. Inhibitor costs assumed as follows: Agrotain Ultra @ $105/gal ($9.23/acre) and Agrotain Plus SC for UAN @ $22.40/gal ($15.75/acre). Study conducted at Owensboro, KY.
We all know the obvious difference between ESN and UAN (urea-ammonium nitrate solution). UAN is a 28-32% liquid nitrogen source and ESN is a 44% granular nitrogen source.
There are several more differences to consider when choosing a nitrogen source:
