Biological fixation — Cropland nitrogen per unit area over time
- Southern Africa
- Zambia
How they compare
Zambia currently reports 28.37 kg/ha against 15.37 kg/ha in Southern Africa, a difference of 13 kg/ha.
That makes Zambia's figure about 1.8 times Southern Africa's.
The two have swapped places 7 times across 63 shared years of data; in 1961 it was Southern Africa ahead.
Southern Africa ranks 10th and Zambia ranks 15th of 29 groups.
Across the 7 decades both report, Southern Africa averaged higher in 3 and Zambia in 4.

About this data
The Cropland Nutrient balance domain contains information on the flows of nitrogen, phosphorus, and potassium from mineral fertilizer, manure applied, atmospheric deposition, crop removal, and biological fixation over cropland and per unit area of cropland. The flows are aggregated to total inputs and total outputs, from which the overall nutrient balance and nutrient use efficiency on cropland are calculated. Statistics are disseminated in units of tonnes and in kg/ha, as appropriate. Nutrient use efficiency is expressed as a fraction (%).
