Integrated Crop Management is published by the Department of Entomology , Iowa State University , Ames, Iowa. Because of abnormal nitrogen fertilizer production, import, and supply this year and with perhaps a short spring application season, some crop producers may use a form of nitrogen fertilizer with which they are unaccustomed. A review of application equipment considerations can help ensure that your nitrogen fertilizer is properly applied. This article focuses on anhydrous ammonia and is the second in a series of three articles about nitrogen fertilizer application and equipment.
Safety when using anhydrous ammonia is a primary consideration.
Direct exposure to skin can cause caustic burns because ammonia bonds with water. Long sleeves and pants, lined rubber gloves, and unvented goggles are standard personal protective gear. Exposure to eyes can result in blindness, and inhalation that damages lung tissue can be fatal. A properly fitted respirator with ammonia cartridges is recommended for operators who frequently work with valves and other connections. Because ammonia is under pressure inside hose lines, fittings, and knives it is important to inspect equipment and keep it in good repair.
