Nitrification inhibitors (NIs), DCD (dicyandiamide), and DMPP (3,4‐dimethylpyrazole phosphate), in combination with urea (UR) and ammonium sulfate nitrate (ASN) fertilizers were studied under contrasting soil textures (sand, loam, and clay) from cultivated soils collected in Brazil and Germany. Soil samples were incubated over 50 days and the content of ammonium ( N - NH4 + ), nitrate ( N - NO3 - ), and soil pH were measured periodically. Applied NIs delayed the nitrification process across all soil textures. Correlation analysis indicated that combining ASN with NIs resulted in higher NH4 + content and efficiency in delaying the nitrification process with high N‐conversion rate (r = –0.82). The combination of ASN+ DMPP increased the efficiency of the N‐conversion rate (r = –0.86) due to H+ release in soil, while UR+DCD (r = –0.50) had an efficiency of the N‐conversion rate similar to UR (r = –0.42). All the NIs had a better performance in reducing N - NO3 - formation in sandy soils as compared to the loam and clay textured soils. Use of DMPP with an N fertilizer results in a soil pH decrease and can be an option to increase the efficiency of the N‐conversion rate, reducing N losses in soil. Overall, our results suggest that NIs have a better performance in reducing N - NO3 - formation in sandy soils as compared to that of the loam and clay textured soils. Use of DMPP with ASN results in a soil pH decrease and can be an option to reduce N losses in soil.

“…Under field capacity moisture application of DCD with prilled urea kept significantly less nitrates at 2 and 3 weeks after incubation. These results are in accord with those of Amberger (1981) and Joseph and Prasad (1993). Nitrate-N in soil due to DCD application with prilled urea under submergence was not significantly different from that under prilled urea.…”

A laboratory study at the Indian Agricultural Research Institute, New Delhi showed that DCD was an efficient nitrification inhibitor under field capacity moisture ( 7 30 kPa) but not so under submerged soil conditions. Nitrification inhibition by DCD was 79.6% after 1 week of incubation and decreased to 59.3% after 3 weeks of incubation under field capacity moisture, while it was only 19.3% after 1 week of incubation and 10.6% and 18.4% after 2 and 3 weeks of incubation under submergence, respectively. DCD can play an important role in reducing N losses from agricultural fields.

An incubation experiment was conducted to determine the nitrification inhibition potential of Brachiaria humidicola (B. humidicola) and their effect on nitrification process. The pots soil was mixed 2 mg of nitrogen through ammonium sulphate. Seven treatments were evaluated viz. control, four root extracts of B. humidicola called as biological nitrification inhibitors (BNIs) (i.e., 70 % ethyl alcohol, 40 % ethyl alcohol, phosphate buffer solution and 2 M KCl salt solution extracts) and two standard chemical inhibitors i.e. dicyandiamide and neem oil coating. The amount of NH 4? -N was reduced 20.66-11.91 lg g -1 soil and NO 3 --N increased 28.89-31.18 lg g -1 soil from 14th to 22nd day time interval. Percent nitrification inhibition was more in BNIs (70 and 40 % alcohol extract) treated soils compared to plant based and synthetic nitrification inhibitors. The nitrification inhibition by B. humidicola also varied it was maximum (64.71 %) observed at 14th day over 22nd day (49.63 %).
