Nitrogen (N) fertilizer incorporation of efficiency enhancer is a well-established practice aiming at reducing N loss while enhancing crop yield. However, the effect different kinds on use (NUE) and gas are rarely compared poorly comprehended. Here, we conducted field experiment involving combination urease nitrification inhibitor (NI), biological eugenol (DE) bioploymer poly-glutamic acid (PG) their combinations (NI + PG, NI DE, PG DE) to evaluate effects yield, NUE, NH3 volatilization greenhouse emissions (GHGs). Results indicated that NI, significantly enhanced uptake NUE. DE all effective in N2O emission, averagely decreased by 11.13%, 6.83%, 8.29%, respectively, 11.15%, 4.32%, 8.35%, have no significant CO2-C CH4-C fluxes, except increases emission thus global warming potential. The these three enhancers has multiply maize NUE loss. These findings help screen can be more effectively utilized agricultural practices contribute application strategies within systems.

Nitrogen (N) fertilizers increase agricultural yields, but also lead to the release of greenhouse gases nitrous oxide (N2O) and ammonia (NH3). This not only reduces efficiency N use, results in climate change loss biodiversity. The use nitrification inhibitors may improve reduce emission gases. We tested three (NZONE MAX, Piadin N-(n-butyl) thiophosphoric triamide (NBPT)) added two common (urea urea ammonium nitrate (UAN)) determined emissions CO2, N2O NH3 evaluate effectiveness these our understanding soil nitrogen cycle. NBPT effectively reduced volatilization by 50% (from 3.0 g NH3-N m−2 alone 1.4 + NBPT). decreased 0.98 N2O-N 0.15 from 0.81 UAN 0.39 Piadin) inhibiting conversion NH4+ NO3−. However, although was found be an effective inhibitor, risk higher 4.5 with addition cannot neglected environmental economical evaluations.

Abstract Ensuring sufficient fertilizer nitrogen (N) for crops while minimizing N losses requires best management practices optimized climate, crop, soil, and root zone hydrology. In Ontario, pre‐plant fertilization of corn ( Zea mays L.) is common; however, this practice extends the time between application significant interception by plant, potentially increasing risk loss through soil nitrous oxide emissions, ammonia (NH 3 ) volatilization, nitrate leaching. These contribute to greenhouse gas affect air quality ), are a substantial financial loss. This study compared three placement methods (broadcast urea [BrUrea], broadcast incorporated [BrIncUrea], injected ammonium [InjUAN]) presence or absence metabolite inhibitors (urease inhibitor [UI], urease plus nitrification [UI+NI]). Fertilizer was applied immediately before planting (150 kg ha −1 all treatments except control. Averaged over yr (2015–2017), NH were reduced 34% from BrIncUrea, 42–55% BrUrea+UI+NI BrIncUrea+UI+NI, 99% InjUAN relative BrUrea (21 ). On average, increased grain yields 83% control (6 t There no annual yield differences among methods. It concluded that incorporation injection in use emissions when pre‐plant.
