- Algeria
- Polynesia
How they compare
Polynesia currently reports 1.38 kg/ha against 1.25 kg/ha in Algeria, a difference of 0.13 kg/ha.
That makes Polynesia's figure about 1.1 times Algeria's.
The two have swapped places 14 times across 63 shared years of data; in 1961 it was Polynesia ahead.
Algeria ranks 159th and Polynesia ranks 158th of 191 countries.
Across the 7 decades both report, Algeria averaged higher in 1 and Polynesia in 6.

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 (%).
