Technology that enables polluting emissions from agricultural systems to be reduced based on handling nitrogen fertiliser and irrigation, the use of nitrification and urease inhibitors, handling automatic gas measurement systems (NOx, NH3 and N20) in the field and data management.

Technological Offers type


Available from: 2015

Handling nitrogen fertilisation to reduce emissions

Description of the services offered

  1. Developing tests under real farming conditions
  2. Obtaining the GHG and NOx emission curve under various fertiliser formulas and irrigation systems with automatic measuring systems in-situ.
  3. Carrying out tests with 15N to quantify processes in the N Quantification cycle of NH3 volatilisation using micro-meteorological techniques.
  4. Optimisation of fertiliser handling (inorganic and organic)

Needs requested and applications

The agricultural industry¿s adaptation to the European Green Deal compels improvement to efficiency in the use of resources in agricultural systems over the next decade (2030). At the COAPA Research Group we do specialist reports and consultancy on greenhouse gas emissions and other contaminant gases on agricultural land (NH3 and NOx) and we help in designing and reviewing industrial research studies aimed at constructing innovative solutions. We provide facilities, equipment and human resources to carry out product studies and testing, and always seek the best way to protect the research results.

Sector or area of application

Fertiliser companies

Differential skills

The COAPA Group consists of 11 doctorate researchers, 3 trainee researchers and 2 technicians and is led by the Senior Lecturer, Antonio Vallejo. The services are carried out by specific staff with high technical and research qualifications in agriculture-based emission mitigation strategies (nitrogen fertiliser handling, use of nitrification and urease inhibitors, irrigation-fertilisation interaction and crop rotation), handling automatic gas measurement systems in the field (NOx, NH3, N2O) and data management (storage codes, data study and statistical analysis), which ensure the high quality of the services the group offers.

Previous references for provision of services

Over the past 5 years, the group has taken part in 16 projects with companies, foundations and associations in the fertiliser industry and associations of producers, and directed 5 Spanish projects and 4 international projects (AgroGreen-SUDOE, Towards INMS,International Atomic Energy Agency, International Institute for Applied Systems Analysis). It has also coordinated two regional projects (AGRISOST) using the technology set out in this offer.
