“…Grain yield for the nitrification inhibitors was ranked pronitridine at 9.4 L ha -1 (9.02 Mg ha -1 ) = pronitridine at 18.7 L ha -1 (9.01 Mg ha -1 ) = non-treated (8.94 Mg ha -1 ) ≥ nitrapyrin (8.63 Mg ha -1 ). Differences between pronitridine and nitrapyrin might be due to differences in the longevity of these products in the soil or the ability to affect ammonia volatilization (Fox & Bandel, 1989;Aita et al, 2014;Frame, 2017). Yield data indicate that adequate N was supplied to the crop for high yields at 202 kg N ha -1 or greater, and no advantage was observed when adding a nitrification inhibitor when compared to the nontreated control.…”

“…Nitrification inhibitors have been utilized not only to reduce gaseous and leaching loss of N fertilizer by delaying nitrification of N fertilizers in the soil (Bremner & Blackmer, 1979;Aulakh et al, 1984;Bronson et al, 1992;Delgado & Mosier, 1996;Weiske et al, 2001;O'Callaghan et al, 2010;Khalil, 2011;Omode & Vyn, 2013;Aita et al, 2014;Fisk et al, 2015;Frame, 2017), but also to increase crop yields (Randall et al, 2003;Ruser & Schulz, 2015;Ren et al, 2017). The most consistent results in the north central U.S. with nitrapyrin (2-chloro-6-(trichloromethyl) pyridine) and dicyandiamide (DCD) were reported on coarse-textured soils with reduced rates of N (Malzer et al, 1989).…”

Nitrification inhibitors have been used to enhance the efficiency of nitrogen fertilizers. This research evaluated the effectiveness of nontreated urea ammonium nitrate (UAN) at 0, 67, 135, 202, and 270 kg N ha -1 as well as UAN treated with nitrification inhibitors (pronitridine at 9.4 and 18.8 L ha -1 or nitrapyrin at 0.5 kg a.i. ha -1 ) to enhance N uptake and increase yield of corn (Zea mays L.). The study took place from 2012-2014 in upstate Missouri on a claypan soil. During the experiments, environmental conditions (high, medium, and low yielding years) affected corn response to pronitridine and nitrapyrin. In general, UAN plus pronitridine at 9.4 L ha -1 had similar effects on corn compared pronitridine at a higher (18.7 L ha -1 ) rate. During a high-yielding year (2014), in order to produce yields equivalent to 67 kg N ha -1 plus pronitridine at 9.4 L ha -1 or nitrapyrin, UAN needed to be increased 14 to 19%. Similarly, the amount of nontreated UAN needed to be increased 8 to 11% for yields to be equivalent to UAN at 135 kg N ha -1 plus pronitridine at 9.4 L ha -1 or nitrapyrin. Grain N removal and agronomic efficiency was highest with pronitridine at 9.4 L ha -1 and nitrapyrin combined with 67 and 135 kg N ha -1 , respectively. This research indicates that pronitridine was as effective as nitrapyrin when added to a pre-emergence application of UAN placed between the rows in a dribble band.

“…Sometimes urease and nitrification inhibitors are jointly added to urea fertilizer to decrease leaching and volatilization losses, but some recent studies have shown that nitrification inhibitors increase NH 3 losses by maintaining high soil pH due to urea hydrolysis, thus reducing the benefit of the urease inhibitor (Frame, 2017;Kim et al, 2012). In a study under controlled conditions, the mixture of both inhibitors caused the NH 3 losses to be like that of the nontreated urea (Soares et al, 2012).…”

Despite the significant inroads into increasing agricultural productivity in recent decades, nitrogen remains a key limiting factor for crop growth and yield. Though highly variable globally, the amount of reactive N added yearly onto cropland that is subsequently lost to the environment remains high. As such the interest in agronomic approaches to address this and improve nitrogen use efficiency (NUE) is currently very high. Here, we have shown the combined approaches of management interventions such as no-till, intercropping with leguminous and grass species, use of nitrogen inhibitors, and combined crop-livestock systems offer considerable potential for enhancing NUE and are already being readily deployed in the tropics. Grass species such as Brachiaria in particular have demonstrated enormous potential via their deep root architectures to reduce losses by leaching. However, the potential for increases in NUE through interaction and association of the root systems with the soil microbial community via rhizodeposits remains a major area for future research. Increasingly it is recognized that truly enhancing NUE requires consideration of the whole system. Improving

“…Extensive research has been conducted on NI's with several reviews on the effects of NI's on the reduction of N loss and the impact on crop production (Aulakh, Rennie, & Paul, 1984;Burzaco, Ciampitti, & Vyn, 2014;Cerrato & Blackmer, 1990;Cook et al, 2015;Fisk, Maccarone, Barton, & Murphy, 2015;Frame, 2017;Prasad, 1995;Wolt, 2004). Research on NI's has shown positive, neutral, or negative effects on grain yield (Quemada, Baranski, Nobel-de Lange, Vallejo, & Cooper, 2013;Wolt, 2004).…”

Nitrogen (N) losses due to leaching, denitrification and/or ammonia volatilization are of utmost concerns since they reduce farm profitability and adversely affect environmental quality. To combat these N losses, a new nitrification inhibitor (NI), pronitridine, can be used to slow down the nitrification process. A two-year (2014, 2015) field experiment was conducted to evaluate the effectiveness of pronitridine at different rates (9.4, 18.7, and 28.1 L ha-1) with anhydrous ammonia (AA) at 112 kg N ha-1 when applied in the fall or pre-plant on claypan soils in northeast Missouri. Using pronitridine at 9.4 L ha-1 with AA in the fall during a low yielding year (2015) increased corn grain yield 7% compared to AA + nitrapyrin (2.3 L ha-1). Agronomic efficiency and yields were greatest with pronitridine at 9.4 L ha-1 than AA + nitrapyrin. Grain N removal was highest for AA + pronitridine at 18.7 L ha-1 compared to AA + nitrapyrin. Pre-plant application of AA + pronitridine at 9.4 L ha-1 increased grain starch content compared to AA without NI, but it was not significantly different from AA + nitrapyrin. Results indicated that pronitridine was effective in increasing yields when applied in the fall and was similar to other NI’s when applied pre-plant in the spring.
