Aim: Develop plants and planting strategies that result in reduced emissions from soil.
What does success look like?
Low nitrous oxide plants and strategies adopted on farm
How will we get there?
What input is needed?
Science is needed to identify and understand plant effects on soil processes related to nitrous oxide emissions.
Commercial input will be needed, if plant varieties/breeding are agronomically sensible, to gather data to support incorporation into New Zealand farming practice.
Commercial input will also be needed if natural nitrous oxide inhibitors are identified to evaluate and breed
What's the timeline?
"POTENTIAL TO REDUCE N2O EMISSIONS FROM URINE PATCHES: Trials aligned with the FRNL programme have demonstrated the potential of feed management options and plant species to reduce N2O emissions from urine patches during 2015/16. Monoculture trials have shown that plantain and lucerne had around 35-70% lower emissions than perennial or Italian ryegrass and white clover at the same level of nitrogen (N) supply. Linking in with a P21 trial using winter forage crops and crop-specific urine, showed that, at the same rate of urine-N returned, N2O emissions from fodder beet were about 40% lower than from a kale crop."
