of UK GHG emissions; –But is responsible for 76% of all UK Nitrous oxide (N2 O) emissions –and 38% of UK Methane (CH4) emissions • UK target for 80% emissions reduction by 2050
as farming is a biological activity – lots of variables, largely microbiological and biochemical processes • Need to understand where GHGs are emitted in agricultural processes and where are the opportunities for constructive intervention • Defra’s current £14m project for more accurate figures for agricultural emissions in UK
KPI’s and improving production intensity • Understand the biological processes that generate emissions • Understand the relative scale of emissions through the production process • Focus on areas that will have greatest impact
all arable emissions from use of N fertilizers for crop production • Half through manufacture, half from field application • 10- 30 % of all N fertilizer applications wasted • Only 3-5% lost as N2O emissions • Target sourcing and application
–ADAS Tried and Tested/ NFU Nutrient management tools • Avoid applications to waterlogged soils, immediately after or prior to rain • Timing application to crop’s growth • Precision farming to target applications across field
CO2 through respiration of micro organisms • Frequency and intensity of tillage open up SOM aggregates to oxidation • England and Wales 25 year soil survey - average loss of SOM in farmland 0.6%/year • Soil carbon pools, stable, steady, active – role of humus – 30-90T carbon/ha in top 30cm • Minimum tillage, CTF systems
health, replacement rate etc) will reduce GHG/litre milk • Diet modulation • Legumes to replace N fertilizers • Manure management and application 50% less N2O emissions from spring application • N fertilizer application, timing and rates
atmosphere at scale • Need for more robust data on sequestration rates • Soil for long term sequestration of carbon • Biomass for short term CO2 removal • Australian government approved on farm sequestration payments earlier this month
