Abstract
- The article presents a study that compares the soil nitrous oxide (N<superscript>2</superscript>) and nitric oxide (NO) emissions, yields, and N use efficiency (NUE) in corn production system in an irrigated loan sandy soil via three different N fertilizers. The study is conducted at the University of Minnesota's Sand Plain Research Farm in Becker, in which the site soil was well drained sandy, mixed, and frigid Entic Hapludoll with loamy texture. It details the result of the study in which anhydrous ammonia (AA) releases more N<superscript>2</superscript>O but less NO, while broadcast urea emits less of the former.
