“…In contrast, for the dry conditions, the initial rise persisted for two days before gradually declining throughout the experimental period. Previous studies have demonstrated that volatilization can persist for 1-9 days, depending on the soil condition and the source of the fertilizer (BEAUCHAMP et al, 1982;Molen et al, 1990). However, losses can be more prolonged, particularly when the initial soil moisture content is high.…”

The complex interactions between soil types, compaction, and moisture on nitrogen transformation processes, such as ammonia volatilization, ammonification, nitrification, and denitrification, were examined using a simulated columns study. Over the course of 30 days, two different soil types—loam and sandy loam—were subjected to three different compaction treatments (control, surface, and sub-surface compaction), and two different moisture treatments (dry and wet). Urea ammonium nitrate (32-0-0) was used as nitrogen fertilizer at the rate of 200 kg N/ha. Measurements were made of important indicators of nitrogen transformations, such as residual concentrations of ammonium and nitrate, nitrate leaching, ammonia volatilization, and nitrous oxide emissions. The findings showed that compaction increased residual ammonium concentrations in deeper soil profiles and decreased nitrification rates in both soil types. Loam soil showed increased nitrate leaching due to higher rates of nitrification and residual nitrate concentrations. The interaction of compaction and moisture had the greatest impact on nitrous oxide emissions, with the highest emissions observed in control treatments during simulated dry weather. The results highlight the significance of taking soil texture, moisture, and compaction into account when implementing sustainable nitrogen management techniques in agriculture. Based on these findings, a number of recommendations are put forth for effective nitrogen management, including the avoidance of broadcast application in moist soil to reduce ammonia volatilization and improve nitrogen use efficiency, and split application to reduce potential nitrate leaching and nitrous oxide emissions from loam soil.

“…The 0-minute samples were taken after removing the acid traps and before closing the lid. The samples were collected on days 1, 3,5,7,9,11,13,15,17,19,21,23,25, and 29. Gas samples were analyzed for N 2 O using gas chromatography (450-GC, Varian) and an electron capture detector (Mosier and Mack, 1980).…”

Loam soil showed increased nitrate leaching due to higher rates of nitrification and residual nitrate concentrations.

Higher ammonia volatilization was observed in moist sandy loam soil under control treatment.

In this study, the complex interactions between soil types, compaction, and moisture on nitrogen (N) transformation processes such as ammonia (NH3) volatilization, ammonification, nitrification, and denitrification were examined over a 30-day period using a simulated column approach. Two soil types: loam, and sandy loam, were subjected to three compaction treatments—control, surface, and sub-surface compaction—and two moisture regimes, dry and wet. Liquid urea ammonium nitrate (32-0-0) was used as the N fertilizer source at a rate of 200 kg N ha-1. Key indicators of N transformations were measured, including residual concentrations of ammonium (NH4-N) and nitrate (NO3-N), NO3-N leaching, NH3 volatilization, and nitrous oxide (N2O) emissions. Findings revealed that compaction significantly increased residual NH4-N concentrations in deeper soil profiles, with the highest 190.80 mg kg-1 recorded in loam soil under sub-surface compaction and dry conditions. Nitrification rates decreased across both soil types due to compaction, evidenced by elevated residual NH4-N levels. Increased NO3-N leaching was observed in loam soil (178.06 mg L-1), greater than sandy loam (81.11 mg L-1), due to initial higher residual NO3- in loam soil. The interaction of compaction and moisture most affected N2O emissions, with the highest emissions in control treatments during dry weather at 2.88 kg ha -1. Additionally, higher NH3 volatilization was noted in moist sandy loam soil under control conditions at 19.64 kg ha -1. These results highlight the necessity of considering soil texture, moisture, and compaction in implementing sustainable N management strategies in agriculture and suggest recommendations such as avoiding broadcast application in moist sandy loam and loam soil to mitigate NH3 volatilization and enhance N use efficiency, as well as advocating for readjustment of fertilizer rate based on organic matter content to reduce potential NO3-N leaching and N2O emissions, particularly in loam soil.
