Lassaletta et al. – 50 year trends in nitrogen use efficiency of world cropping systems: the relationship between yield and nitrogen input to cropland

This dataset measures the nitrogen balance of agricultural inputs and outputs.

Nitrogen inputs are measured as the application of nitrogen to crops either from synthetic fertilizers, or organic sources such as manure.

Nitrogen output is measured as the nitrogen produced in the form of crops.

Nitrogen use efficiency (NUE) is the ratio between nitrogen inputs and output. A NUE of 40% means that only 40% of nitrogen inputs are converted into nitrogen in the form of crops. The remaining 60% is lost to the environment as a pollutant.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
