Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
The database used for meta-analysis consisted of 46 studies published between 1980 and 2017 in peer-reviewed scientific journals. The studies assessed the buffer zone effects on nitrate-N or the total N in the surface runoff or on nitrate-N in the groundwater. Data were extracted from tables and digitized from figures using the ImageJ 1.37 program.
