The effect of the nitrification inhibitor dicyandiamide (DCD) on nitrous oxide and methane emissions after cattle slurry application to Irish grassland

Impacts of feedlot floor condition, deposition frequency, and inhibitors on N2O and CH4 emissions from feedlot dung and urine patches

“…Meanwhile, the enhanced NH 3 emissions from urine patches due to the application of DCD and HQ were similar to the findings in the study by Luo, Li, and Luo et al (2013). In addition, this study found that applying DCD increased the CH 4 emission rate (Table 5), which might be an indirect consequence that the ammonia monooxygenase capable of oxidizing CH 4 was inhibited by DCD as well (Bedard and Knowles 1989;Cahalan, Ernfors, and Müller et al 2015). Overall, the frequency of manure deposition at one site partly reflecting animal stocking density and feedlot surface condition in terms of the duration length being used for stocking animals plays an important role and should be included when determining feedlot EFs.…”

Effect of cattle slurry application techniques on N2O and NH3 emissions from a loamy soil

“…Comparing different application techniques, slurry injection might significantly increase direct N 2 O emission when compared to broadcast application ( Wulf et al., ; Velthof and Mosquera , ), whereas different surface application techniques (splashplate or bandspread) did not affect N 2 O emissions ( Cahalan et al., ). After slurry injection, the soil area directly above the injection slot was shown to be the main emitting area ( Dittert et al., ) due to creation of anaerobic hotspots in the injection slot promoting denitrification ( Flessa and Beese , ; Severin et al., , ).…”

Effect of nitrification inhibitors on the content of available nitrogen forms in the soil under maize (Zea mays, L.) growing

“…In this study, the nitrification inhibitors dicyandiamide and 1,2,4 triazole were efficient tools for reducing content of nitrate nitrogen and increasing content of ammonium nitrogen in the agricultural soil. Many authors (Cui et al, 2011;Di and Cameron, 2012;Moir et al, 2012;Pfab et al, 2012;Cahalan et al, 2015) state that, the application of dicyandiamide together with NH4 + -based fertilizers has shown efficiency in reducing nitrogen losses in the form of NO3 -leaching. Thus, a large number of studies have shown that nitrogen fertilizers with nitrification inhibitors are more environmentally friendly (Zaman et al, 2007;Zaman et al, 2009;Zaman and Blennerhassett, 2010;Ding et al, 2011).…”
