H1 – Reduction of tillage intensity

Description:

Reducing tillage saves fuel and strengthens humus buildup and thus CO2 storage in the fields

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

If the soil is tilled less about 5-15l of fuel per hectare can be saved and if no longer turned, the humus content can be increased. If a 10% increase can be achieved in 5 years around 13t of CO2 can be stored per hectare

 

How to get it done
What is to be done
Especially with no-till tillage (e.g. no-till), no longer turn the soil but conserve it
Impact
Medium
Potential to be realised and possible conflict of interest
Changing tillage needs to be part of the entire cropping system and will need different management and machines to cope with weeds, diseases and crop reminder in order to keep or increase sustainable yield levels
Roadmap and time horizon
1-5 years
Cost
Reduced cost through less tillage. There is going to be a yield dip for a few years to fully establish the new system and mangement
Investment
New tillage and seeding equipment. If with normal replacement cycle no additional investment, if not can be significant and several €10’000 up to €100’000 for an average European farm
Financing
Bank loan, leasing, agricultural investment funds, national schemes
How to measure, assess impact and whom to talk to
Impact
Medium impact through fuel savings, savings in gray energy from machines and C storage in soil
What to measure
Soil carbon content and fuel / machinery use
How to measure
Fuel measures from machines, soil carbon with sampling and satellite input, gray energy from machines with C-balance tools
Solution providers
AgriCircle (www.agricircle.com), Treffler (www.treffler.net) and other machinery producers, local extension service
Farmer acceptance
Medium (16% of farmers in AgroCO2ncept have implement measures by 2020). First steps are rather easy, but the less tillage, the more demanding and the bigger the change

H2 – Reduction of passages and soil load

Description:

Vehicles should not exceed a maximum contact area pressure and a minimum number of trips should be achieved through optimal equipment, crop rotation, plot structure, etc.

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

The reduced passes and wheel loads can save energy and prevent soil compaction or denitrification due to lack of oxygen

How to get it done
What is to be done
Matching of attachment system (number of trips) and machine park (wheel loads) by means of Terranimo/TIM and carbon balancing tools
Impact
Medium
Potential to be realised and possible conflict of interest
Combination of different passages might lead to side effects like soil can not rest / dry before drilling and bigger, heavier machines
Roadmap and time horizon
1-5 years
Cost
Reduced cost through less passages
Investment
Might need new equipment. To be evaluated case by case
Financing
Own resources, Bank loan, national schemes
How to measure, assess impact and whom to talk to
Impact
Medium impact through fuel and energy savings and the prevention of soil compaction or denitrification due to lack of oxygen
What to measure
Soil carbon content and fuel / energy use
How to measure
Fuel measures from machines, soil carbon with sampling and satellite input
Solution providers
AgriCircle (www.agricircle.com), Terranimo (www.terranimo.ch – Also directly included in AgriCircle), flotation tyre producers and tyre pressure systems such as from PTG (www.ptg.info)
Farmer acceptance
Medium (11% of farmers in AgroCO2ncept have implement measures by 2020). First savings are easy. Further optimizations become harder

H3 – Optimization of spatial utilization structures and use of GPS-technology

Description:

Improvement of cross-farm spatial structures, e.g. through melioration, leasehold land consolidation and land use exchange, as well as improvement of on-farm management structures as well as the use of GPS technology for parallel driving

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

On optimally shaped and used surfaces, machining is simplified, the distances traveled are reduced, and thus the effort and energy consumption are minimized. Also overlapping / headland in cultivation is minimized and leading to savings in fertilizer, seeds and crop protection

How to get it done
What is to be done
Potential analysis based on the plot and management plans and evaluation of best fitting GPS solution
Impact
High
Potential to be realised and possible conflict of interest
Exchange of land can also lead to friction amongst the farming community and lead to less collaboration leading to higher emissions
Roadmap and time horizon
5-10 years
Cost
Cost of melioration and h of discussions amongst farmers to agree on changes. Annual licences of GPS-RTK signal of €0-1’500/year
Investment
Cost of melioration, invest in GPS devices of around €15’000-25’000 per tractor
Financing
Own resources, National schemes
How to measure, assess impact and whom to talk to
Impact
High impact through reduced fuel and energy consumption and less overlapping / less headland in cultivation minimizing inputs
What to measure
Fuel and energy use, amount of overlap in cultivation
How to measure
Fuel and energy measures from machines, overlap with drones or measuring on the ground
Solution providers
AgriCircle (www.agricircle.com), FMIS and machinery producers, open source GPS solutions such as CEREA (https://cerea-forum.de/forum) or AgOpenGPS (http://agopengps.gh-ortner.com/doku.php), drone producers such as DJI (www.dji.com), Yuneec (www.yuneec.com), Sensefly (www.sensefly.com)
Farmer acceptance
Medium (32% of farmers in AgroCO2ncept have implement measures by 2020). Needs inter-company approaches
