Overview of the role of nitrogen for food and fibre production and the implications of this for GHG emissions
The three presentations in this webinar will cover the role of N in various agricultural systems, the estimation of Nitrogen Usage Efficiency (NUE), the sources, drivers and size of N related Greenhouse gas (GHG) emissions losses, and global N emissions assessment.
Optimising fertiliser application – what level of precision can we achieve?
