How this figure is calculated
Maize (corn) — Crop residues (N content) divided by Land area (sq. km), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Maize (corn) — Crop residues (N content) ÷ Land area (sq. km)
Computed from
- Maize (corn) — Crop residues Food and Agriculture Organization of the United Nations
- Land area FAOSTAT, Food and Agriculture Organization of the United Nations (FAO)
Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
