“…Adding nitrification inhibitors (NIs) into N fertilizer is an effective method for enhancing NUE and reducing N losses. NIs restrict nitrification by inhibiting the ammonia oxidation process (Benckiser et al 2013) , which is the substrate for denitrification (Chen et al 2019;Zhang et al 2018;Zhao et al 2017). In addition, NIs could reduce methane (CH 4 ) and carbon dioxide (CO 2 ) emissions by reducing soil acidification, which affects the hydrolyzation of soil carbonate, and by enhancing the activity of CH 4 monooxygenase (MMO) (Fan et al 2019;Zhang et al 2015).…”

“…However, co‐application of urea with NBPT and nitrification inhibitors, such as DMPP, does not always produce the optimum combined effect on reducing N loss, especially NO 3 − loss. Previous studies have found that NBPT, DMPP and another nitrification inhibitor, DCD, were negatively affected by each other when co‐applied in acid and calcareous soils 3, 16, 17 . We speculate that this was because: (i) DMPP is acidic (pH = 2.5–3.1) 12 accelerating the degradation of NBPT 18 and (ii) some chemical reactions may have occurred between DMPP and NBPT, and between DCD and NBPT 19 .…”

Background3,4‐Dimethylpyrazole phosphate (DMPP) is a nitrification inhibitor which can restrict nitrate (NO3−) production. Boric acid is a substance which inhibits urease activity. However, few studies have focused on the inhibitory effect of boric acid on urea hydrolysis and the possible synergistic effect with DMPP. Thus, an incubation trial was conducted to determine the impact of boric acid and DMPP addition on urea‐N transformation, and their synergistic effects, in chernozem soil (Che) and red soil (RS). Four treatments were set up in each soil: urea only (U); urea combined with DMPP (UD); urea combined with boric acid (UB); and urea combined with both DMPP and boric acid (UDB).ResultsCompared to U, adding DMPP (UD) increased NH3 emissions by 11% and 13% and decreased soil NO3−‐N concentration by 38% and 13% in Che and RS, respectively. Boric acid addition (UB) effectively prolonged the half‐life time of urea by 0.8 and 0.4 days, reduced NH3 volatilizations by 11% and 16% and delayed the occurrence of NH3 emission peaks for 3 and 4 days in contrast to U treatment in Che and RS, respectively. UDB treatment mitigated the NH3 volatilizations caused by the addition of DMPP (UD) by 16% and 29% in Che and RS, respectively. Additionally, a better nitrification inhibition rate was found in the UDB treatment compared to other treatments in both soils.ConclusionsThere is potential to develop a new N transformation inhibition strategy with the use of a combination of boric acid and DMPP. © 2020 Society of Chemical Industry

“…The total growth period was 230 days, with six developmental stages recognized: (i) seeding (0–17 DAS), (ii) tillering (18–150 DAS), (iii) elongation (151–179 DAS), (iv) anthesis (180–193 DAS), (v) grain filling (194–214 DAS), and (vi) dough ripening (215–230 DAS). Precipitation was 147 mm and the soil temperature ranged from −1.6 to 29.7 °C during the wheat growing season (Zhao et al, 2017). The soil water content of each pot, which was controlled gravimetrically to simulate local wheat production, was adjusted daily to 65% (during the seedling stage), 70% (tillering), 80% (elongation), 80% (anthesis), and 70%–75% (grain-filling) of the field water-holding capacity in accordance with the amount of rainfall and evaporation.…”

Information on the homogeneity and distribution of 13carbon (13C) and nitrogen (15N) labeling in winter wheat (Triticum aestivum L.) is limited. We conducted a dual labeling experiment to evaluate the variability of 13C and 15N enrichment in aboveground parts of labeled winter wheat plants. Labeling with 13C and 15N was performed on non-nitrogen fertilized (−N) and nitrogen fertilized (+N, 250 kg N ha−1) plants at the elongation and grain filling stages. Aboveground parts of wheat were destructively sampled at 28 days after labeling. As winter wheat growth progressed, δ13C values of wheat ears increased significantly, whereas those of leaves and stems decreased significantly. At the elongation stage, N addition tended to reduce the aboveground δ13C values through dilution of C uptake. At the two stages, upper (newly developed) leaves were more highly enriched with 13C compared with that of lower (aged) leaves. Variability between individual wheat plants and among pots at the grain filling stage was smaller than that at the elongation stage, especially for the −N treatment. Compared with those of 13C labeling, differences in 15N excess between aboveground components (leaves and stems) under 15N labeling conditions were much smaller. We conclude that non-N fertilization and labeling at the grain filling stage may produce more uniformly 13C-labeled wheat materials, whereas the materials were more highly 13C-enriched at the elongation stage, although the δ13C values were more variable. The 15N-enriched straw tissues via urea fertilization were more uniformly labeled at the grain filling stage compared with that at the elongation stage.
