Aims The objective of this study was to evaluate dry matter (DM) production of Urochloa brizantha cv. Marandu and ammonia volatilization in response to rates and sources of enhanced-efficiency N fertilizers. Methods The experiment was installed in a pasture area, evaluated over two growing seasons. A randomized block design with four replications was used, in a 4x2+1 factorial arrangement, consisting of four N sources (Urea - Ur Conv ; Ammonium nitrate - AN; Ureia+NBPT - Ur NBPT ; Urea+Duromide - Ur Duromide ) and two nitrogen rates (100 and 200 kg ha -1 year), plus a treatment without nitrogen fertilization (control). Results At both N rates, ammonia volatilization from Ur Conv100/200 was highest. Ammonia volatilization was lower after Ur NBPT and Ur Duromide application, with values similar to AN. Ammonia losses from Ur Duromide tend to be lower than from Ur NBPT . The N use efficiency in dry matter production of Marandu was influenced by the N sources and rates. At both N rates, the efficiency of Ur Duromide and Ur NBPT was greater than that of Ur Conv . With regard to total DM and leaf percentage in response to N rates, DM production increased after 200 kg N ha -1 rates in response to all sources, in both years. Conclusions The Ur Duromide reduce N losses by volatilization compared to Ur NBPT and Ur conv, and resulted in greater total DM production and relative leaf production of Marandu, in comparison to Ur NBPT, AN and Ur conv.

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.

In no-till (NT), liming and urea fertilization are performed on the soil surface, which can increase nitrogen (N) losses via ammonia volatilization. On the basis of N fertilization management, gypsum application provides a promising alternative for improving N uptake by plants. Therefore, the objective of this study was to evaluate the N behavior loss by NH3-N volatilization, the soil pH at a depth of 0 – 0.05 m, leaf N content, and N uptake by second-season corn after lime and gypsum application in a Rhodic Ferralsol under NT. Overall, the treatments consisted of a 4 × 4 factorial arrangement with four lime rates (0, 2.6, 5.4, and 8.1 Mg ha-1) and four gypsum rates (0, 4, 8, and 12 Mg ha-1). During the study period, second-season corn was cultivated for two years and fertilized with urea, for which the N losses through ammonia volatilization, soil pH, leaf N content, and N uptake values were quantified. The losses through ammonia volatilization were subjected to nonlinear regression using a logistic model, and the other variables were subjected to linear regressions. The lime applied by broadcasting on the soil surface in the NT increased the pH of the topsoil and increased N losses via NH3-N volatilization in the second-season corn. Further, the N losses in the NT treated with lime accounted for 58% of the applied N, which increased by 2.3 to 2.5% for each Mg ha-1 of lime applied. Therefore, lime or gypsum application did not improve the status of N in second-season corn in soils with low acidity and no S deficiency.
