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 conditions 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 transparent 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:precision farming equipment for application costs 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 spread 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: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:medium
  • Potential to be realised and possible conflict of interest:use of precision farming will make farmers more transparent 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: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 spread 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: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: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:compost production with cost of €10-20 per ton of compost
  • Investment: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 spread 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:low
  • 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:improved sprayer with cost of about €10’000-30’000 per sprayer
