Graeme Schwenke, NSW Department of Primary Industries (NSW DPI) soil scientist, says field trials with urea showed that ammonia loss due to volatilisation averaged 11% (5-19%) when applied to fallow paddocks, and 5% (3-8%) when applied to wheat crops... "At the time the crystalline form was comparable in price per unit N to urea and people were spreading it on fallow paddocks ahead of a crop but weren't sure how much would be lost through volatilisation... "Our research showed that volatilisation losses from ammonium sulphate were often only half that from urea, unless the soil contained calcium carbonate (lime) where the opposite was the case...
