Description Nitrification and denitrification are the primary drivers for generating reactive -N (NO3-, N20 and NO) the two processes of N-cycle, largely responsible for soil-N losses, resulting poor N-recovery and low-NUE in agricultural systems. Suppressing soil nitrifier activity facilitates retention of soil mineral-N as ammoninum, leads to better utilization of N in situations where
nitrification is followed by N losses via leaching and/or denitrification. Soils in the WCS (West Central Sahelian zone of Africa) where sorghum is predominantly grown, are of light-textured sandy-loams with acidic (ph 5.0 to 6.0). Alfisols in India and Ultisols in South America are also of light-textured and acidic, where most of the sorghum grown globally. Nitrogen mineralized from SOM (soil organic matter) or from inorganic fertilizers is quickly nutrified and lost through leaching.
