Recording available : BNI Flagship – Key driving genetic, environment and management factors that influence nitrous oxide mitigation in tropical and temperate crops
This webinar presents the findings of a global meta-analysis examining the factors that regulate the effectiveness of biological nitrification inhibition (BNI) in reducing nitrous oxide (N₂O) emissions from agricultural systems. BNI is a plant-mediated process in which certain metabolites inhibit soil nitrifying microorganisms, slowing the conversion of ammonium to nitrate and potentially reducing N₂O emissions. By synthesizing results from 23 published studies, this analysis evaluates the influence of genetic, environmental, and management factors on cumulative N₂O emission reduction. The results highlight that plant genus and species, soil physical characteristics (including texture, clay and sand content, and bulk density), soil nutrient status (such as soil organic carbon, total nitrogen, available phosphorus, NH₄⁺ and NO₃⁻), drainage conditions, irrigation, geographic factors, measurement timing, and nitrogen fertilization practices (type and application rate) are key drivers shaping BNI effectiveness.
