Description

Direct application of urea containing fertilizers (dry urea and UAN solutions) has increased markedly over the past two decades throughout Illinois, Iowa, and Minnesota (Fig.l). They now account for about 35% of the total N market (Fig.2). In that same time period, ammonium nitrate has decreased from 10 to less than 1 percent and anhydrous ammonia from approximately 80 to 65 percent of the market in Iowa, Illinois, and Indiana.
