Project F1: “Measure”Environmental and management drivers of non-CO2 greenhouse gas emissions in agro-ecosystemsIan Galbally, CSIRO AR: 

Project F1: “Measure” Environmental and management drivers of non-CO2 greenhouse gas emissions in agro-ecosystems Ian Galbally, CSIRO AR Standard Protocols Develop methods N2O Chamber methods SF6 methane method Micro-met methods Methane calorimetry Incubation methods Measure baseline non-CO2 emissions from: Dairy & intensive grazing Grains Cotton Quantify impact of management and identify key drivers eg. Irrigation/ Water N fertiliser management Crop rotation Forage management

Potential BMPs: 

Potential BMPs Minimise surplus nitrate in the soil Fertiliser Management Source, rate and timing (split) of N applications Nitrate N sources Match crop or pasture demand Avoid high nitrogen fertiliser rates. Warm and waterlogged soils Coated/chemically treated fertilisers Controlled-release Nitrification inhibitors Crop & Pasture management Reduce fallow N fixing crops Plant breeding Other nutrients Animal stocking rate Soil management Reduced tillage Irrigation and drainage Soil compaction Incorporate stubble
