Tunisia vs USSR: Biological fixation — Cropland nitrogen per unit area
Biological fixation — Cropland nitrogen per unit area over time
- Tunisia
- USSR
How they compare
USSR currently reports 2.04 kg/ha against 1.91 kg/ha in Tunisia, a difference of 0.13 kg/ha.
That makes USSR's figure about 1.1 times Tunisia's.
The two have swapped places 4 times across 31 shared years of data; in 1961 it was USSR ahead.
Tunisia ranks 150th and USSR ranks 148th of 191 countries.
USSR has averaged higher in every one of the 4 decades both report.
Head to head by decade
| Decade | Tunisia | USSR | Difference | Ahead |
|---|---|---|---|---|
| 1960s | 0.8599 kg/ha | 2.44 kg/ha | 1.58 kg/ha | USSR |
| 1970s | 1.43 kg/ha | 2.36 kg/ha | 0.9349 kg/ha | USSR |
| 1980s | 1.5 kg/ha | 2.61 kg/ha | 1.11 kg/ha | USSR |
| 1990s | 1.57 kg/ha | 2.51 kg/ha | 0.936 kg/ha | USSR |
Averages of every year both report within each decade.

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 (%).
