OAR@ICRISATBiological nitrification inhibition (BNI) activity in sorghum: Potential role for enhancing nitrogen-use efficiency (NUE)G VSubba RaoauthorKNakaharaauthorYAndoauthorK LSahrawatauthorS PDeshpandeauthorPSrinivasa RaoauthorH DUpadhyayaauthorC THashauthorNitrification 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.Sorghum2015Society for Millets Research, ICAR Indian Institute of Millets ResearchBook Section
