Initial profiling of Biological Nitrification Inhibition in New Zealand’s elite ryegrass cultivars

Proven in temperate crops and tropical pastures, Biological Nitrification Inhibition (BNI) may offer a natural plant-mediated means to combat N₂O emissions in grazed temperate livestock systems. Herein we report initial investigation into BNI using a broad set of New Zealand’s elite ryegrass genetics in a standard hydroponic bioassay, concluding a 12-month CCAAE Early Investment funded project. During the project we have met twice with seed industry and pastoral sector stakeholders and received positive feedback on project progress, findings and the potential for BNI to reduce agricultural N₂O emissions.
