Emissions from agricultural fields

In the coming years, agriculture faces a major transition to reduce emissions of ammonia and greenhouse gases, including the potent nitrous oxide, which constitutes the primary source of emissions from cultivated areas. To achieve ambitious national and international reduction targets, there is an urgent need for effective technologies and mitigation measures in agriculture. These may include various cultivation, fertilisation and tillage strategies, as well as biochar and fertiliser additives (e.g. nitrification inhibitors).

Documented effects of climate and environmental technologies

For new technologies and measures aimed at reducing field emissions to be considered at national and international levels, their effectiveness must be documented based on measurements under representative field conditions. We work with a variety of methods to determine emissions, for example via manual flux chambers combined with gas chromatography analysis of samples, or continuous measurements using automatic flux chambers and state-of-the-art measuring instruments.

We therefore offer:

  • Advisory services and expertise for the development of technologies and strategies to reduce field emissions.
  • Documentation of the mechanisms of action for a given measure under controlled conditions (e.g. prior to testing in field trials).
  • Documentation of the effect of a technology or cultivation strategy on nitrous oxide emissions, as well as other related sources of nitrogen loss, under representative cultivation conditions in field trials.
  • Documentation of ammonia volatilisation during fertiliser application.

So, if you or your company have a promising technology, product or cultivation strategy that can contribute to reducing nitrous oxide emissions from fields, please feel free to contact us to learn more about the possibilities.
