The efficiency of urea-based fertilizers is substantially reduced through nitrogen (N) losses via ammonia volatilization. Soil pH, clay content, soil organic matter (SOM), and field capacity can affect ammonia loss. Incubation experiments were conducted on eight soils using a controlled environment system to study the effects of soil properties on ammonia volatilization from urea and urea ammonium nitrate (UAN) applied at 134.5 kg N/ha. Each experiment was set up as a randomized complete block design with four replicates. Ammonia loss was measured on 1, 2, 3, 4, 5, 6, 7, 9, 11, 13, and 16 DAF (days after N application). …
