Short summary

Available historical global N fertilizer map as an input data to global biogeochemical model is still limited and existing maps were not considered NH₄⁺ and NO₃⁻ in the fertilizer application rates. In our products, by utilizing national fertilizer species consumption data in FAOSTAT database, we succeeded to estimate the ratio of NH₄⁺ to NO₃⁻ in the N fertilizer map. The products could be widely utilized for global N cycling studies.
