Summary
Executive summary
Nature of the issue
Reactive nitrogen (Nr) has well-documented positive effects in agricultural and industrial production systems, human nutrition and food security. Limited Nr supply was a key constraint to European food and industrial production, which has been overcome by Nr from the Haber–Bosch process.
Given the huge diversity in Nr uses, it becomes a major challenge to summarize an overall inventory of Nr benefits. This full list of benefits needs to be quantified if society is to develop sound approaches to optimize Nr management, balancing the benefits against the environmental threats.
Approaches
When reviewing trends in European Nr production rates, including those from chemical and biological fixation processes, and the consumption of this Nr in human activities, agriculture is by far the largest sector driving Nr creation.
Particular attention has been given to relationships between N application rates, productivity and quality of products from major crops and livestock types, including consideration of the mechanisms underlying variations in N response/outputs and the derived impacts on land use and land requirements.
Key findings/state of knowledge
The economic value of N benefits to the European economy is very substantial. Almost half of the global food can be produced because of Nr from the Haber–Bosch, and cereal yields in Europe without fertilizer would only amount to half to two-thirds of those with fertilizer application at economically optimal rates.
