Analysis
The most recent figure for biological fixation — cropland nitrogen per unit area in Angola is 9.57 kg/ha, measured in 2023.
The figure is up 5.5% on the previous year and up 5.3% over ten years.
Over the whole period, biological fixation — cropland nitrogen per unit area in Angola peaked at 9.94 kg/ha in 2014 and was at its lowest, 1.51 kg/ha, in 1990.
That places Angola 74th out of 191 countries 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 (%).
