  • N2O ✔
  • CH4 ✔
  • Energy 
  • Resources 

What it does

Reduction of methane formation in the covered slurry tank as well as reduction of nitrous oxide

How to get it done

  • What is to be done:identify potential solutions that fits purpose and define an investment plan
  • Impact:high
  • Potential to be realised and possible conflict of interest:investment can be substantial
  • Roadmap and time horizon:1-5 years
  • Cost:interest rate/depreciation of investment
  • Investment:between €30/m3 – €230/m3 for slurry tank to be covered
  • Financing:bank loan, agricultural investment funds, national schemes

How to measure, assess impact and whom to talk to

  • Impact:high impact with reduction of methane formation in the covered slurry tank as well as reduction of nitrous oxide. Will lead to increased slurry nutrient content
  • What to measure:volume of slurry tank covered in m3 and additional nutrient content
  • How to measure:volume (m3) of slurry and respective modelling. Repeated lab analysis of slurry before and after coverage
  • Solution providers:Ceno-tec (www.ceno-tec.de), Stallkamp (www.stallkamp.de), PAS (www.pastanks.nl), Milieusystemen (www.milieusystemen.nl)

D2 – Manure storage and Compostation

Description

Use of appropriate composting methods for manure to reduce emissions and to promote soil quality

Impact

  • CO2 
  • N2O ✔
  • CH4 ✔
  • Energy 
  • Resources 

What it does

Reduction of methane formation in manure as well as reduction of nitrous oxide and promotion of humus build up

How to get it done

  • What is to be done:determine and implement the appropriate procedure together with the local extension service
  • Impact:medium
  • Potential to be realised and possible conflict of interest:potential investment is substantial and implementation is labour intensive. Operations are demanding. There might be conflicts with local rules and building codes to get operations realized
  • Roadmap and time horizon:1-5 years
  • Cost:compostation site and machines as well as necessary labour. Need additional substrate for compostation that is paid for to break even
  • Investment:between €10Ks and €100Ks to get up and running
  • Financing:bank loan, agricultural investment funds, national schemes

How to measure, assess impact and whom to talk to

  • Impact:medium impact trough reduction of methane formation in manure as well as reduction of nitrous oxide and promotion of humus build up. Can lead to higher soil fertility and higher crop yields
  • What to measure:tons of compost produced and its use as well as reduced kgs of mineral fertilizers
  • How to measure:tons of compost produced and applied to be recorded as well as mineral fertilizer being replaced
  • Solution providers:GujerInnoTec AG (www.gujerinnotec.com)
  • Farmer acceptance:low (14% of farmers in AgroCO2ncept have implement measures by 2020). Acceptance increases if humus build up measured

D3 – Slurry tank in soil

Description

Use of appropriate composting methods for manure to reduce emissions and to promote soil quality

Impact

  • CO2 
  • N2O 
  • CH4 ✔
  • Energy 
  • Resources 

What it does

By storing the slurry in the soil, it is cooled to below 10°C and microbial methane-generating processes are slowed down

How to get it done

  • What is to be done:determine and implement the appropriate procedure together with the local extension service
  • Impact:medium
  • Potential to be realised and possible conflict of interest:potential investment is substantial. There might be conflicts with local rules and building codes
  • Roadmap and time horizon:1-5 years
  • Cost:interest rate and depreciation of investment
  • Investment:several €100Ks
  • Financing:bank loan, agricultural investment funds, national schemes

How to measure, assess impact and whom to talk to

  • Impact:medium impact trough reduction of methane formation in manure. Will lead to higher nutrient content of manure and respective reduction of mineral fertilizers
  • What to measure:volume (m3) of slurry tank in soil and its use as well as kg of mineral fertilizers reduced
  • How to measure:volume (m3) of slurry from tank in soil applied to be recorded as well as mineral fertilizer being replaced
  • Solution providers:local construction company, LBG (www.lbg-bau.ch)
  • Farmer acceptance:medium (50% of farmers in AgroCO2ncept have implement measures by 2020)

D4 – Slurry tank aeration

Description

GHG emissions are reduced by appropriate aeration measures of the slurry (e.g. weekly stirring)

Impact

  • CO2 
  • N2O ✔
  • CH4 ✔
  • Energy 
  • Resources 

What it does

GHG emissions are reduced by appropriate aeration measures of the slurry (e.g. weekly stirring)

How to get it done

  • What is to be done:adopt daily/weekly operations and update slurry tank installations, if needed
  • Impact:low
  • Potential to be realised and possible conflict of interest:easy to implement. Potential investment is minimal
  • Roadmap and time horizon:1-5 years
  • Cost:machines, working hours and energy use for stirring/ventilation
  • Investment:€0 – €5’000
  • Financing:own ressources

How to measure, assess impact and whom to talk to

  • Impact:low impact trough reduction of methane formation in manure and nitrous oxide emissions. Will lead to higher nutrient content of manure and respective reduction of mineral fertilizers
