Biological fixation — Cropland nitrogen per unit area in Southern Africa, 1961–2023
Source: Food and Agriculture Organization of the United Nations. Measured in kg/ha.
Analysis
Southern Africa recorded 15.37 kg/ha for biological fixation — cropland nitrogen per unit area in 2023. That is the highest value across all 63 years on record.
That represents a change of up 19.0% on the previous year and up 144.2% over ten years.
Over the whole period, biological fixation — cropland nitrogen per unit area in Southern Africa peaked at 15.37 kg/ha in 2023 and was at its lowest, 1.92 kg/ha, in 1995.
That places Southern Africa 12th out of 37 regions with data for 2023, putting it in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.

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 (%).
