Feeding the soil, as well as the crop for carbon growth
FarmOnline, Other, 04/01/2024
At face value farmers looking to cut greenhouse gas emissions could be forgiven for looking to cut their use of nitrogen (N) fertiliser, which has a high carbon footprint to produce due to the energy intensive manufacturing process. […] CSIRO researcher John Kirkegaard, who has authored several reports into N management in farm systems, recently worked on a paper prepared by lead author Maartje Sevenster on rethinking N-fertiliser and greenhouse gas balances in cropping systems, using data from Dr Kirkegaard’s long-term agronomic trial run for 30 years at Harden in southern NSW.
