Synthetic nitrogen application rates by crop and country
Source:R/datasets.R
mueller_synthetic_n.RdCountry- and crop-process-level synthetic nitrogen application rates (kg N ha\(^{-1}\)), derived from Mueller et al. (2012). Used as reference crop-specific N rates in the WHEP nitrogen pipeline.
Format
A tibble with one row per crop-process-country combination containing:
proc_code: Internal process code (e.g."p001").crop_process: Descriptive crop process name (e.g."Rice production").crop_original: Crop name as in the source dataset.unit: Unit of the rate value (always"kgN/ha").iso3c: ISO 3166-1 alpha-3 country code.rate_value: Nitrogen application rate (kg N ha\(^{-1}\)).
