I1 – Optimization of fertilizer type and quantity

Description:

The reduction of N surpluses to nitrous oxide is to be avoided by optimally adapting nutrient applications to plant requirements and reducing fertilizer and machinery use

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

If sub-field plant needs and soil condition as well as weather patterns are more strongly incorporated into fertilization plans, leaching and volatilization of ammonia, for example, can be reduced by up to 30%

How to get it done
What is to be done
Field-related fertilizer planning combined with precision farming and satellite data to determine sub-field plant needs and soil condition with soil nutrient content including Nmin measurement
Impact
High
Potential to be realised and possible conflict of interest
Use of precision farming will make farmers more tranparent which is not what farmers want to see
Roadmap and time horizon
1-5 years
Cost
Cost of precision farming equipment and tools. Usually such optimizations to get improved application maps cost somewhere between €3-20/ha. Cost of additional soil sampling of about €15/ha and year
Investment
Investment into precision farming equipment for application with additional cost of about €5’000-20’000 per spreader
Financing
Own resources, bank loan, agricultural investment funds, national schemes
How to measure, assess impact and whom to talk to
Impact
High impact through better adjustment of fertilizers to plant needs leading to less leaching and volatilization of nutrients
What to measure
Fertilizer purchased and used vs. yield achieved
How to measure
Amount of fertilizer spreaded through farmers records and machines and yield achieved through farmers records and machines / satellites to measure and check yield
Solution providers
AgriCircle (www.agricircle.com), Yara (www.yara.com) and many more FMIS providers as well as fertilizer and machinery producers. So far a good tool that also includes N-stabilisation and type of fertilizer to be used is not existing
Farmer acceptance
High (74% of farmers in AgroCO2ncept have implemented measures by 2020)

I2 – Optimization of fertilizer application and incorporation

Description:

The distribution of fertilizer is to be optimized so that all fertilizers and especially also the farm’s own fertilizers such as liquid manure, dung and compost can develop its full value in plant nutrition

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

With the help of technical adjustments during application, nitrogen losses in particular, but also energy consumption, are reduced

How to get it done
What is to be done
Application e.g. with drag hoses, precision spreaders. Also conceivable are hosing, slurry drill, cultan fertilization and precision farming
Impact
Medium
Potential to be realised and possible conflict of interest
Use of precision farming will make farmers more tranparent which is not what farmers want to see
Roadmap and time horizon
1-5 years
Cost
Additional cost for maintenance of more complex machines. To be evaluated case by case
Investment
Investment into precision farming equipment for application with additional cost of about €20’000-100’000 per spreader / tanker. If slurry tanker with sensor to measure nutrients that is another €40’000-60’000 for the sensor only
Financing
Own resources, bank loan, agricultural investment funds, national schemes
How to measure, assess impact and whom to talk to
Impact
Medium impact through better application and less nitrogen losses in particular, but also less energy and input consumption
What to measure
Fertilizer applied vs. yield achieved
How to measure
Amount of fertilizer spreaded through farmers records and machines and yield achieved through farmers records and machines / satellites to measure and check yield
Solution providers
Machinery producers such as Amazone (www.amazone.net), Rauch (rauch.de), Bogballe (www.bogballe.com), Samson Agro (www.samson-agro.com), Kotte Landtechnik (www.kotte-landtechnik.de)
Farmer acceptance
High (79% of farmers in AgroCO2ncept have implemented measures by 2020)

I3 – Humus build-up and C storage through compost

Description:

Compost stabilizes and promotes humus on the fields and reduces the use of mineral fertilizers

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

In humus carbon is stored directly on the fields and with the saving of mineral fertilizer grey energy is saved (approx. 5 kg CO2/kg nitrogen)

How to get it done
What is to be done
Production and spreading of own compost after selection of suitable (possibly inter-company) composting systems. Planning and development of a business plan to build and operate the compostation site needed
Impact
Medium
Potential to be realised and possible conflict of interest
Depending on local law and building codes it can take years to get a permit to build a compostation site
Roadmap and time horizon
5-10 years
Cost
Additional cost for compost production with cost of €10-20 per t of compost
Investment
Investment into compost production site and machinery ranging from a few €10’000 up to millions
Financing
Own resources, bank loan, agricultural investment funds, national schemes
How to measure, assess impact and whom to talk to
Impact
Medium impact through soil carbon sequestration and the saving of mineral fertilizer (approx. 5 kg CO2/kg nitrogen)
What to measure
Soil carbon sequestration and fertilizer applied
How to measure
Measurement of soil carbon with soil sampling and satellite data. Amount of fertilizer spreaded through farmers records and machines and yield achieved through farmers records and machines / satellites to measure and check yield
Solution providers
Local extension services, AgriCircle (www.agricircle.com), GujerInnoTec (www.gujerinnotec.com)
Farmer acceptance
High (68% of farmers in AgroCO2ncept have implemented measures by 2020)

I4 – Optimization of the use of crop protection products

Description:

Reduction of plant protection products by means of forecasting systems, higher efficiency in application as well as promotion of beneficial insects

Impact
CO2
N2O
CH4
Energy
Resources

What it does:

The use of pesticides has an impact on a farm’s carbon footprint primarily through their influence on yield and the energy required to produce and apply them

How to get it done
What is to be done
Clarification of technical / structural adjustments as well as potential for forecasting systems on the farm
Impact
Small
Potential to be realised and possible conflict of interest
Saving of crop protection can also lead to higher yield uncertainty and especially lower yield stability and can thus lead to a higher mental load of farmers
Roadmap and time horizon
1-5 years
Cost
Additional cost for maintenance of improved crop protection application technology and cost of forecasting system
Investment
Investment into improved sprayer with cost of about €10’000-30’000 per sprayer
Financing
Own resources, bank loan, agricultural investment funds, national schemes
