“…This finding was in agreement with Martin et al (1997), who stated that soil NO 3 − -N was not affected by DCD, while soil NH 4 + -N was increased or conserved in hyperthermic sandy soils planted with potato at Hastings, the US. After the CF application in the present study, the NI plots tended to have a higher soil NO 3 − -N than the CF plot.…”

“…The observed NI effect suggested that DCD and neem oil effectively slowed down the NH 4 + conversion and prolonged NH 4 + -N in the soil. The studied NIs have a suppressive effect on soil nitrification, because (1) DCD inhibits cytochrome oxidase and decreases the oxidation of NH 4 + to NO 2 − (Di and Cameron 2002) and (2) neem oil contains meliacins that can reduce soil nitrifier activity (Kiran and Patra 2003;Kumar et al 2007 (Martin et al 1997;Kumar et al 2007;Matsushima, Choi, and Inubushi 2009). In a potato field, DCD was effective in slowing nitrification and the soil had a higher soil NH 4 + -N than the applied urea-NH 4 NO 3 with no DCD (Kelling, Wolkowski, and Ruark 2011).…”

“…DCD inhibits the oxidation of NH 4 + to nitrite (NO 2 − ) (Di and Cameron 2002), and relevant studies have shown that DCD could slow down soil nitrification and reduce N 2 O emissions (Pathak and Nedwell 2001;Matsushima, Choi, and Inubushi 2009). Application of DCD to a tuber field crop such as potato has shown the inhibitory effect on nitrification by maintaining soil NH 4 + (Wadman, Neeteson, and Wijnen 1993;Martin et al 1997;Kelling, Wolkowski, and Ruark 2011) and, in some circumstances, increasing tuber yields (Frye et al 1989;Martin et al 1993;Kelling, Wolkowski, and Ruark 2011).…”

The effects of nitrification inhibitors (NIs) on soil nitrous oxide (N 2 O) emission, soil ammonium (NH 4+ ) and nitrate (NO 3 − ), and cassava (Manihot esculenta Crantz) yields were investigated in a loamy sand soil in eastern Thailand. Treatments were chemical fertilizer (CF) and CF plus dicyandiamide (DCD) or neem (Azadirachta indica) oil at two rates of 5% and 10%. DCD had a greater reduction of soil N 2 O flux than the neem oil (P<0.10). DCD and neem oil retained NH 4 + -N in the soil by 79% and 63% (P ≤ 0.10), respectively. The NI effect on soil NO 3 − -N was small due to a low N fertilizer rate. The cassava root yield and N uptake were increased 4-11% and 2-18%, respectively, by use of NIs, but they were only significant for DCD (P ≤ 0.10). These findings suggest that NIs application may be a promising method for minimizing nitrogen loss and enhancing crop yields in a tropical cassava field.

“…in the soil (Prasad and Power, 1995;Trenkel, 1997). NIs have been used to increase yields and to reduce nitrate leaching in several crops (Malzer and Randall, 1985;Frye et al, 1989;Malzer et al, 1989;Walters and Malzer, 1990;Corré and Zwart, 1995;Davies and Williams, 1995;Martin et al, 1997;Trenkel, 1997;Ball-Coelho and Roy, 1999;Serna et al, 2000;Pasda et al, 2001;Díez-López et al, 2008;Li et al, 2008).

The 3,4-dimethyilpyirazole phosphate (DMPP), commercialized as Entec, is a nitrification inhibitor developed by BASF (Germany) that may help to minimize N losses and to obtain a higher profit from N fertilizers. A two-year field trial was established in 2001 in the Northeast of Spain to assess the effects of DMPP on N use efficiency (NUE) and to determine the economic returns. Seven treatments have been carried out comparing the effect of DMPP on pig slurry and on mineral fertilizers. The application of DMPP resulted in better efficiency indexes on mineral fertilizers. An apparent nitrogen recovery of 0.465 kg kg-1, on average, was obtained for the Entec treatment. A net benefit of € 809 ha-1, on average, was obtained for the Entec treatment compared with € 607 ha-1 for the control treatment. The results of this study suggest that the nitrification inhibitor could improve farmer profit in irrigated wheat on a calcareous soil.

This paper reports a 406 day outdoor experiment (performed in pots) to determine the influence of the new nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP), when added to pig slurry (PS), on the growth and chemical composition of ryegrass. Pots containing a loamy, calcareous soil were treated with either no PS or 73.7, 147.3 or 221 cubic cm pot-1, with or without DMPP, prior to seeding with ryegrass. The greatest quantity of above ground dry matter was obtained with the highest dose of PS + DMPP (36.3 g pot-1) 7.4% greater than that obtained for the same treatment without DMPP, and 46.1% greater than with the no PS treatment. The plants treated with the high and medium doses of PS + DMPP absorbed 70% of total N during the first quarter of the experimental season (104 days). Without DMPP, N uptakes were 55.7% and 63% for the high and medium treatments respectively. The inhibition of nitrification with DMPP increased agronomic efficiency and reduced N leaching by 17%.
