Dr Nigel Davies - Muntons PLC - Profiting from Sustainability Feedback Session April 2015

  1. 1. Practical Sustainability What’s in it for you? Dr Nigel Davies – Manufacturing and Sustainability Director
  2. 2. Emissions from Agriculture What are our targets?
  3. 3. GHG Emissions Reduction from Crops Government View Nitrogen measurement and use • 40% farms have no nitrogen management plan (26% by area) • Highest N emissions from soils is where N application is high or soils warm and wet • Use of nitrification inhibitors – cost effective? Precision Farming • 22% use GPs; 20% use soil mapping for nitrogen • 50% of farmers say GPS is too expensive Plant Breeding • Greater influence of root soil interaction • Breeding for nitrification inhibition in spring barley (JHI)
  4. 4. GHG Emissions Reduction from Crops Government View Soil Organic Carbon • No- or reduced-till can increase soil organic carbon? Latest studies suggests it is the same but redistributed differently • Soil C storage too risky due to potential run-off and risk of subsequent nitrous emissions Policy / Legislation • Roadmap of voluntary measures • Sustainable Intensification support • Possible legislation planning in 2016 for 2028-2032
  5. 5. “Our farmers are making an important commitment to reduce their greenhouse gas emissions and we will continue to support them to achieve this … I expect the partner organisations to show clear leadership as industry works to meet this challenge.” Sir James Paice, 2012
  6. 6. GHG Emissions Reduction from Crops Priorities identified and by whom

  11. 11. Carbon Footprint of Malted Ingredients A common currency
  12. 12. Emissions from Crops Analysis
  13. 13. Carbon Footprint: Scopes 1-3 Fuel 17% N2O from Soil 35% N fertiliser 48% Difference between models 6%
  14. 14. .. becoming a ‘low carbon grower’ should not add cost to the production of malting barley … Use of abated nitrogen fertiliser Precision farming techniques that result in more efficient use of/reduction of inputs Use of Green compost to comply with PAS100 ** to improve soil structure/reduce the inorganic fertiliser used Use of alternative fertilisers that comply with PAS110** Nitrogen fixing cover crops Adherence to Conservation Grade/LEAF protocols to improve biodiversity Compliance with the SAI Platform Protocol To qualify as ‘low carbon’ growers must adhere to at least TWO of the following* ** No onions or other products known to taint grain are permitted * In addition to completing a carbon footprint form

  16. 16. Choice of Fertiliser Matters Urea-based fertilisers generate more carbon footprint than solid ammonium nitrate. BUT …… Urea in production has the lowest carbon emission. So control of emissions in soil e.g urease inhibitors can change the balance
  17. 17. Cost effective Choices? Urease inhibitor – why? If Urea applied when it is dry can lose 30% effective N in 72h Nitrification inhibitor – why? Prevents loss of ammonium to nitrate which is easily leached
  18. 18. Range of Carbon Footprints of Farms Supplying Malting Barley
  19. 19. Example Carbon Footprints from HGCA Case Studies

  21. 21. Farmer Sustainability Group meetings What has been discussed so far Topics identified • Cover Crops • Compost Use • Water Use • Precision Farming • External certification Issues: • Implications of low carbon barley supply contract • Emphasise this will not cost farmers more • Must not disadvantage us in securing the quality and quantity of barley we procure • Report back to our farmers about how low carbon barley production can be achieved
  22. 22. LEARN: Chosen specialist topic : You will learn something new Future Farmer Sustainability Group meetings What You Should Expect SHARE: Experiences of applying different sustainable options IMPROVE: You must be enabled to improve your ability to implement sustainable farming practices
