We provided a global gridded, crop-specific fertilization dataset at 5-arc-minute spatial resolution, including the rate, type, frequency, and placement of N inputs in 2000. 2. We downloaded the global gridded crop-specific non-tillage dataset at 5-arc-minute spatial resolution from Porwollik et al, but aggregated the results for other crops. 3. We downloaded the global gridded crop-specific irrigated area dataset at 5-arc-minute spatial resolution from MIRCA2000, but further divided the irrigated rice into either continuously or intermittently flooded systems. <b>License:</b> Creative Commons Attribution 4.0 International Data may be freely downloaded for research, study, or teaching, but must be cited appropriately.
