“…When the numerical data were not included by a study, AV rates and agronomic attributes were extracted from figures using GetData Graph Digitizer software version 24. We used Equation (8) to calculate missing data of NUE (Equation ( 5)), then we used AV F (Equation (1)) with Equations ( 4)- (7) to calculate adjusted YSFP AV , NUE AV , NAE AV, and PAN AV (Equations ( 11)-( 14)) (Table 1). All data were input in Microsoft excel 2013 package.…”

“…The emitted ammonia from N fertilizers to the atmosphere was determined as 60% and expected to increase dramatically under the accelerated growth in fertilizer use [6]. The emitted ammonia from wheat, maize, and rice in China was 2.24, 4.75, and 3.69 Tg, respectively, causing significant economic losses and environmental hazards [7].…”

“…The feasibility of applying the chosen strategy for AV mitigation has an economic impact, which is indicated by plant production that is outweighed by the environmental impact of the farmer. The common agronomic parameters are yield-scaled fertilizer productivity or yield-scaled AV (YSFP), nitrogen use efficiency (NUE), nitrogen agronomic efficiency (NAE), and productivity of applied nitrogen (PAN), represented by Equations ( 4)- (7), respectively (Table 1). YSFP and PAN are functions of yield and applied N rate without taking control into consideration, contrary to NAE, while NUE is a function of changes in nitrogen uptake between treatment and control and the applied N. We hypothesized that these parameters differ in their sensitivity to reflect the effect of AV on crop yield, thus the main objectives were: (1) Testing the sensitivity of agronomic parameters to AV from different crops under various agronomic conditions and practices.…”

Economic losses and environmental hazards are meaningful problems of emitted ammonia induced by extensive use of synthetic nitrogen fertilizers. The concept presented as yield scaled fertilizer productivity (YSFP) in our meta-analysis in addition to nitrogen use efficiency (NUE), nitrogen agronomic efficiency (NAE), and productivity of applied nitrogen (PAN) were used to weight ammonia emission (AV)-induced reductions in wheat, maize, and rice production. The comprehensive meta-analysis was used to weight the reductions in these parameters by AV as the difference between observed means of the collected studies and their adjusted means using AV factor. There were higher reductions in agronomic production induced by AV in rice than maize and wheat. AV-induced reductions in PAN of rice, maize, and wheat were decreased by 4.99, 3.71, and 2.42 (kg grains kg−1 N), respectively. YSFP and PAN recorded the highest sensitivity to AV in wheat (R2 = 0.88 for both) and rice (R2 = 0.92 and 0.89, respectively), while NUE was the most efficient parameter in weighting AV agronomic effects (R2 = 0.81). Slow-released N fertilizers resulted in the lowest reductions in AV agronomic parameters followed by organic amendments and then urea while using other synthetic fertilizers recorded the highest reductions by 3.90, 6.40, 1.41, and 4.70 in YSFP, NUE, NAE, and PAN, respectively. Inhibitors had the highest effect on mitigating AV agronomic losses compared with biochar and mulching and affected the parameters following that order as percentages of no amendments, YSFP (52.63%) > PAN (47.18%) > NUE (40.83%) > NAE (38.75%). This study outlines the reductions in agronomic production induced by AV and weights the efficiency of various mitigation strategies under various agronomic conditions. The results proved the efficiency of YSFP with NUE parameters to weight the effect of AV on crop yield, while suggesting to find out more applicable parameters in further studies.

“…Urea hydrolysis is considerably limited in a low-moisture environment and can lead to a great loss of N through ammonia emissions ( Klimczyk, Siczek & Schimmelpfennig, 2021 ). Precipitation has a close connection with NH 3 –N emissions ( Li et al, 2015b ; Abdo et al, 2021 ). Rainfall of up to 3 mm nearly after fertilizer application can increase NH 3 –N emission, while precipitation of 71.4 mm can reduce ammonia emission by 84.0% ( Sanz-Cobena et al, 2011 ).…”

Nitrogen fertilizers play a key role in crop production to meet global food demand. Inappropriate application of nitrogen fertilizer coupled with poor irrigation and other crop management practices threaten agriculture and environmental sustainability. Over application of nitrogen fertilizer increases nitrogen gas emission and nitrate leaching. A field experiment was conducted in China’s oasis irrigation area in 2018 and 2019 to determine which nitrogen rate, plant density, and irrigation level in sole maize (Zea mays L.) cropping system reduce ammonia emission and nitrate leaching. Three nitrogen rates of urea (46-0-0 of N-P2O5-K2O), at (N0 = 0 kg N ha−1, N1 = 270 kg N ha−1, and N2 = 360 kg N ha−1) were combined with three plant densities (D1 = 75,000 plants/ha−1, D2 = 97,500 plants/ha−1, and D3 = 120,000 plants/ha−1) with two irrigation levels (W1 = 5,250 m3/hm2 and W2 = 4,740 m3/hm2) using a randomized complete block design. The results showed that, both the main and interaction effects of nitrogen rate, plant density, and irrigation level reduced nitrate leaching (p < 0.05). In addition, irrigation level × nitrogen rate significantly (p < 0.05) reduced ammonia emission. Nitrate leaching and ammonia emission decreased with higher irrigation level and higher plant density. However, high nitrogen rates increased both nitrate leaching and ammonia emission. The study found lowest leaching (0.35 mg kg−1) occurring at the interaction of 270 kg N ha−1 × 120,000 plants/ha−1 × 4,740 m3/hm2, and higher plant density of 120,000 plants/ha−1 combined with 0 kg N ha−1 and irrigation level of 5,250 m3/hm2 recorded the lowest ammonia emission (0.001 kg N)−1. Overall, ammonia emission increased as days after planting increased while nitrate leaching decreased in deeper soil depths. These findings show that, though the contributory roles of days after planting, soil depth, amount of nitrogen fertilizer applied and year of cultivation cannot be undermined, it is possible to reduce nitrate leaching and ammonia emission through optimized nitrogen rate, plant density and regulated irrigation for agricultural and environmental sustainability.
