“…A irrigation water (11.4 mm)applied by center pivot system was sufficient to incorporate urea and reduce N-NH 3 losses to 5.5% of the N applied to wheat crops in sandy soil. On the other hand, in non-irrigated area, the N-NH 3 loss by volatilization reached a mean value of 60% of the N applied to wheat crops (Holcomb et al, 2011).…”

The market of stabilized, slow and controlled release nitrogen (N) fertilizers represents 1% of the world fertilizer consumption. On the other hand, the increase in availability, innovation and application of these technologies could lead to the improvement of N use efficiency in agroecossystems and to the reduction of environmental impacts. The objective of this study was to quantify agronomic efficiency relative index, ammonia volatilization, and CO 2 emissions from conventional, stabilized and controlled release N fertilizers in corn summer crop. The experiment was carried out in a corn crop area located in Lavras, state of Minas Gerais, Brazil, without irrigation. All treatments were applied in topdressing at rate of 150 kg ha -1 N. N-NH 3 losses from N fertilizers were: Granular urea (39% of the applied N ) = prilled urea (38%) > urea coated with 16% S 0 (32%) = blend of urea + 7.9% S 0 + polymers + conventional urea (32%) > prilled urea incorporated at 0.02 m depth (24%) > urea + 530 mg kg -1 of NBPT (8%) = Hydrolyzed leather (9%) > urea + thermoplastic resin (3%) = ammonium sulfate (1%) = ammonium nitrate (0.7%). Thermoplastic resin coated urea, ammonium nitrate and ammonium sulfate presented low values of cumulative CO 2 emissions in corn crop. On the other hand, hydrolyzed leather promoted greater C-CO 2 emission, when compared with other nitrogen fertilizers.Index terms: CO 2 ; NH 3 loss; no-tillage; Zea mays L. RESUMOO consumo de fertilizantes nitrogenados estabilizados, de liberação lenta e controlada representa 1% do total de fertilizantes utilizados no mundo. Por outro lado, um aumento na disponibilidade, inovação e utilização dessas tecnologias pode levar a maior eficiência no uso do nitrogênio (N) na agricultura com menor impacto ambiental. O objetivo deste trabalho foi quantificar as perdas de amônia (N-NH 3 ) por volatilização e as emissões de CO 2 de fertilizantes nitrogenados convencionais, estabilizados e de liberação controlada na cultura do milho. O experimento foi realizado em condições de campo no município de Lavras (MG) no ano agrícola 2013/2014, sem irrigação. Os tratamentos foram compostos por fertilizantes nitrogenados aplicadas em cobertura na dose de 150 kg ha -1 de N. A perda acumulada de N-NH 3 dos fertilizantes nitrogenados convencionais, estabilizados de liberação controlada em ordem decrescente foi: Ureia granulada (39% do N aplicado) = ureia perolada (38%) > ureia + 16% de S 0 (32%) = mistura física de grânulos (blend) de ureia revestida com S 0 e polímeros e ureia convencional (32%) > ureia perolada incorporada (24%) > ureia + 530 mg kg -1 de NBPT (8%) = hidrolisado de couro bovino (9%) > ureia + resina termoplástica (3%) = sulfato de amônio (1%) = nitrato de amônio (0,7%). O sulfato e nitrato de amônio e a ureia + resina termoplástica promovem a menor emissão de dióxido de carbono (C-CO 2 ) em área de cultivo de milho. Enquanto que, o hidrolisado de couro promoveu a maior emissão total de C-CO 2 para à atmosfera.Termos para indexação: CO 2 ; perdas de NH 3 ; planti...

“…Therefore, soil moisture sufficed to hydrolyze urea in both treatments, but irrigation after fertilization significantly reduced NH 3 -N losses -probably through its effect of incorporating fertilizer into the soil (Rochette et al, 2013). Adsorption of NH 4 + by negative soil charges and buffering of a rise in soil pH around granules (Holcomb III et al, 2011) strongly decreased volatilization rates: from 17 to 2 kg ha -1 d -1 on the second day after N fertilization ( Figure 2a). A similar effect was previously reported by Holcomb III et al (2011): irrigation with 21.6 mm water reduced NH 3 -N losses from 53.4 to 2.8 % applied N, which they ascribed to incorporation of N into the soil.…”

“…High air temperature and moisture and also high wind speed and soil moisture increase volatilization losses by facilitating urea hydrolysis, and do not favor NH 4 + diffusion in soil (Holcomb III et al, 2011;Viero et al, 2015). Although the inhibitor efficiently reduces NH 3 -N losses, it does not always lead to increased grain yields (Abalos et al, 2014;Mota et al, 2015).…”

High nitrogen (N) losses by ammonia (NH 3 ) volatilization from urea can compromise nitrogen fertilization efficiency and corn yield. The purpose of this study was to assess the effects of irrigation management and the addition of the urease inhibitor N-(n-butyl)thiophosphoric triamide (NBPT) on NH 3 -N losses from urea and on corn yield. To this end, two experiments were carried out in the 2011/12 crop season on a sandy clay loam Acrisol in the Central Basin region of Rio Grande do Sul, southern Brazil. Experiment I consisted of two different N sources (urea and urea plus the inhibitor) at a rate of 200 kg ha -1 N and two corn sowing times [viz., an early time (Sept. 3, 2011) and an intermediate time (Oct. 3, 2011)]. Experiment II considered a combination of three irrigation management systems (viz., without irrigation on the fertilization day and on the next 7 days; 20 mm of water immediately before N fertilization; and 20 mm water after N fertilization) and two N sources (urea and urea plus the inhibitor) at 150 kg ha -1 N. A control treatment without topdressed N fertilization was also performed in parallel with the two experiments. The NH 3 -N losses from common urea increased with increasing soil moisture in Experiment I (25 % applied N), and with irrigation before N fertilization in Experiment II (27 % applied N). The inhibitor reduced NH 3 -N losses from urea by 46 to 80 %. Also, irrigation after fertilization reduced ammonia volatilization by 83 % on average, with little effect from the inhibitor. The effects of the inhibitor and post-fertilization irrigation on the mitigation of NH 3 losses by volatilization from urea were not additive; in addition, they led to no increase in corn yield.

Soil mineral nitrogen content and grain yield with enhanced efficiency fertilizers in maize

Urea is the most common N fertilizer worldwide, but N from urea breakdown can be easily lost through ammonia (NH 3 ) volatilization, ammonium (NH 4 + ) nitrification, nitrate (NO 3 − ) denitrification or NO 3 − -leaching processes. Enhanced efficiency fertilizers (EEFs) are formulated to minimize N losses and maximize plant N uptake and crop yields. The capacity of urea EEFs (urea with urease inhibitor, nitrification inhibitor, both urease and nitrification inhibitors, and polymer-coated) to maintain N in the soil profile throughout the growing season was determined by the analysis of [NH 4 + -N] and [NO 3 − -N] in three top-soil depth increments at three dates in three seasons of no-till maize (Zea mays L.). Surface-applied EEFs, untreated urea, and injected urea ammonium nitrate (UAN) were compared at an application rate of 168 kg N ha −1 . Within and across years, soil [NO 3 − -N] and [NH 4 + -N] typically decreased with depth and time since urea application. Among the EEFs, only a polymer-coated urea produced greater [NO 3 − -N] and [NH 4 + -N] at several sampling dates and depths, and greater grain yields than untreated urea across the 3 yr.Nonetheless, the polymer-coated urea resulted in significantly greater fertilizer use efficiency (FUE) than untreated urea in only 1 of 3 yr. Several EEFs increased grain yields compared to untreated urea each year, but FUE generally was similar to that with untreated urea. Environmental conditions influenced the effectiveness of EEFs in improving soil mineral N availability and increasing grain yield.
