“…Therefore, observed differences in crop yields may be attributed to differences in weather conditions, with in-season precipitation likely as a primary factor (2009: 654 mm; 2010: 569 mm; 2011: 372 mm). Concurrent to this research, we found a strong weather influence on NH 3 volatilization losses from these study plots (Torralbo et al, 2022). Precipitation the day of treatment application or shortly thereafter benefits a better distribution and incorporation of N from urea (Savin et al, 2021), and, as described previously (Torralbo et al, 2022), differences in precipitation after fertilization caused distinct NH 3 volatilization rates between years in these experiments.…”

Polymer-coated urea (Duration and ESN) and inhibitor-based urea fertilizer (Agrotain) have proved their efficiency in reducing total NH 3 volatilization losses while also maintaining greater soil [NH 4 + ] than untreated urea for a longer period.…”

“…Soil [NO 3 − –N] differed more among EEFs than soil [NH 4 + –N] at most soil depths, which suggests that considerable urea hydrolysis and subsequent NH 4 + nitrification occurred prior to the first sampling date each year (Zaman et al., 2009). Indeed, ammonia volatilization often peaks in the first 15 d after urea application (Cantarella et al., 2018; Torralbo et al., 2022). Soil [NH 4 + –N] that resulted from the application of polymer‐coated urea as Duration was significantly greater than that from the untreated urea at 0–5 cm in each of the 3 yr.…”

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.

“…Contudo, em taxas demasiadas, o N-fertilizante é subutilizado pela planta (apenas 40-60% é aproveitado), o que geralmente é traduzido em baixa eficiência de uso e/ou menor recuperação do mesmo (DELEVATTI et al, 2019). O N-ureia (fertilizante com melhor custo benefício e maior concentração de N), que é majoritariamente usado nesses casos, sofre intensamente com perdas em solos tropicais (principalmente por volatilização da amônia) (TORRALBO et al, 2022).…”

Nanomaterials associated with plant growth and crop cultivation revolutionize traditional concepts of agriculture. However, the poor reiterability of these materials in agricultural applications necessitates the development of environmentally‐friendly approaches. To address this, biocompatible gelatin nanoparticles (GNPs) as nanofertilizers with a small size (≈150 nm) and a positively charged surface (≈30 mV) that serve as a versatile tool in agricultural practices is designed. GNPs load agrochemical agents to improve maintenance and delivery. The biocompatible nature and small size of GNPs ensure unrestricted nutrient absorption on root surfaces. Furthermore, when combined with pesticides, GNPs demonstrate remarkable enhancements in insecticidal (≈15%) and weed‐killing effects (≈20%) while preserving the efficacy of the pesticide. That GNPs have great potential for use in sustainable agriculture, particularly in inducing plant growth, specifically plant root growth, without fertilization and in enhancing the functions of agrochemical agents is proposed. It is suggested conceptual applications of GNPs in real‐world agricultural practices.
