Data on the effects of crop rotational diversity and nitrogen fertilisation on cereal yields
https://doi.org/10.5878/8af1-0q60
Data contain standardised yields of several different cereals collected between 1958 and 2020 from 32 long-term agricultural trials across North America and Europe. Yields in tonnes per hectare were standardised against the overall mean yield per site across all treatments and years. Treatments include different levels of crop rotational diversity and nitrogen fertilisation.
This data was used in the article: Smith et al., Increasing crop rotational diversity can enhance cereal yields, Communications Earth and Environment, 2023.
See the attached documents for more information, including, ‘Metadata.txt’ for description of data codes, ‘Crop_rotation_information_desc.txt’ and ‘Crop_rotation_information.tsv’ detailing cropping sequence and mean yields of each rotation per site and ‘R_script_Smith_etal.Rmd’ to see how this data was used in the associated article.
R markdown output of the script is provided in the form of R_script_Smith_etal.pdf.

Description of the mode of collection:
Data was originally collected from long-term agricultural trials across Europe and North America (see contributors of data). A research team at SLU collated and formatted the data to fit the purpose of examining the trends for the effects of crop rotational diversity and nitrogen fertilisation on cereal yields across a large geographical range.
