“…At the time of fertilizer application, the soil moisture was low, resulting in small N losses by NH 3 -N volatilization during the first days (Figure 1). This behavior differed from that observed by Minato et al (2020), who applied N fertilizer to second-crop corn and observed maximum NH 3 -N volatilization in the first 72 h after application. Such results were attributed to the high soil moisture at the time of application, which occurred 48 h after a rainfall of 60 mm.…”

“…After to select the model, the data were submitted to nonlinear regression, using the logistic model represented by equation 1, as described by Seber and Wild (2003). The model is traditionally used to estimate cumulative ammonia volatilization (Silva et al, 2017a;Cantarella et al, 2018;Minato et al, 2019Minato et al, , 2020.…”

“…The magnitude of NH 3 -N loss varies according to the technology used in N fertilizers (Liu et al, 2019;Minato et al, 2020), soil properties (Sunderlage and Cook, 2018), and environmental conditions (Otto et al, 2017), hindering analysis of isolated effects of a given factor on NH 3 -N loss, especially under field conditions. Ammonia volatilization increased with N dose, regardless of the source.…”

“…The delay in NH 3 -N peak does not always decrease total NH 3 -N losses; for example, Tasca et al (2011) observed that the NBPT delayed the peaks of volatilization, which occurred in the first week after application. This means that the parameter β deserves caution in the interpretation and cannot be analyzed in isolation, although higher β values are preferable when considering the gaseous losses of N by enhanced efficiency fertilizers (Besen et al, 2021;Minato et al, 2020).…”

Novel fertilizer stabilization technologies are needed to decrease ammonia (NH 3 -N) losses and increase nitrogen use efficiency. Duromide + NBPT is a new technology that combines two molecules, Duromide and NBPT, whose propose is to increase the efficiency of the urease inhibitor NBPT in reducing NH 3 -N loss from urea. Preliminary results showed that Duromide + NBPT can be a more effective product than just NBPT, particularly under low soil pH and high-temperature conditions. This study aimed to compare the effects of urea + Duromide + NBPT, urea + NBPT, and conventional urea on soil N losses by NH 3 -N volatilization. The field experiment was conducted on a Latossolo Vermelho Distroférrico (Oxisol) in Campo Mourão, Paraná, Brazil, using a randomized complete block design with treatments arranged in a 2 × 3 factorial, comprising two N doses (45 and 90 kg ha -1 ) and three N fertilizers (urea + Duromide + NBPT, urea + NBPT, and conventional urea). The NH 3 -N volatilization data were subjected to nonlinear regression using a logistic model. The NH 3 -N losses varied according to dose and fertilizer, reaching up to 12.4 % of the applied N in the conventional urea treatment. Urea + Duromide + NBPT was more efficient than urea + NBPT in decreasing NH 3 -N volatilization. Compared to conventional urea at doses of 45 and 90 kg ha -1 of N, urea + Duromide + NBPT reduced NH 3 -N volatilization losses by 35 and 54 % and from urea + NBPT by 15 and 33 %, respectively. The new stabilizing technology Duromide + NBPT reduced NH 3 -N losses by up to 33 % compared to NBPT alone. Ammonia volatilization was influenced by soil moisture. The volatilization peak, observed after 18-19 days of N fertilizer application, was triggered by rainfall events.
