Fertilizer consumption as a percentage of fertilizer production is a supply-structure ratio, not a measure of fertilizer applied per hectare. The World Bank series compares calculated fertilizer consumption with domestic fertilizer production. For a clean cross-country comparison, this article uses the 72 economies with an actual 2023 observation rather than ranking all 115 most-recent observations together.
That distinction matters because the 115-row file spans observation years from 1967 to 2023. Forty-three economies have a latest non-missing value from before 2023. Treating those values as if they all described the same year would mix time differences with country differences. The 2023 subset gives a smaller but internally consistent comparison.

What does 100% mean in this indicator?
The World Bank description defines fertilizer consumption from production plus imports minus exports. The series covers nitrogenous, potash and phosphate fertilizers, including ground rock phosphate, while traditional animal and plant manures are excluded. On that accounting basis, 100% means calculated consumption equals domestic fertilizer production.
A value above 100% means consumption exceeded domestic production in that year. With positive production, the identity is consistent with imports exceeding exports. A value below 100% means domestic production was larger than calculated consumption, which can occur when exports exceed imports. These are relationships inside the indicator definition; they should not be turned into a complete measure of import dependence without checking the underlying trade and production quantities.
This is also different from the World Bank indicator for fertilizer consumption in kilograms per hectare of arable land. A country can have a very high consumption-to-production percentage because it produces little fertilizer domestically, even if its farm application rate is moderate. Conversely, a large fertilizer producer can have a low ratio while still using substantial amounts on its own farms.
Why the comparison uses 72 economies, not all 115
The source file contains the most recent non-missing observation for 115 economies. Only 72 of those observations are dated 2023. The remaining 43 come from earlier years, with the oldest in 1967. Those older values remain valid historical observations, but they are not suitable for a single-year ranking beside 2023 values.
Mixing them would create a map that looks geographically complete while quietly combining different decades. A color difference might then reflect a change in year rather than a structural difference between countries. Because the package marks a map as optional, the safer presentation is a same-year chart and table for 2023, accompanied by a clear explanation of the coverage gap.
This choice does not convert missing 2023 values to zero and does not discard extreme official values. It simply separates the question “what is the latest available value for each economy?” from the different question “how did economies compare in 2023?” The first can use all 115 rows with a year column; the second should use the 72 observations that share the same year.
The 2023 distribution is strongly right-skewed
Across the 72 economies with 2023 data, the median ratio was 90.78%, while the arithmetic mean was 589.53%. The large gap tells us that a small set of very high ratios pulls the mean upward. The 25th percentile was 36.21% and the 75th percentile was 253.65%, so the middle half of the observations lay roughly between those two values.
The 90th percentile was 655.19%. Thirty-seven economies were below 100%, while 35 were above 100%; none was exactly 100%. Nine had ratios of at least 500%, five were at or above 1,000%, and two exceeded 2,000%. The count around the 100% threshold is fairly balanced, but the magnitudes are not: the upper tail can extend extremely far because production is in the denominator.
Another useful way to read the distribution is by broad bands. Sixteen observations were below 25%, 21 were from 25% to under 100%, 26 were from 100% to under 500%, seven were from 500% to under 2,000%, and two were at least 2,000%. A linear chart spanning the full range would compress most countries near the bottom, which is why the accompanying chart uses a logarithmic horizontal scale.
Why can the ratio exceed 1,000% or even 20,000%?
Estonia recorded the highest 2023 value in the same-year subset at 20,163.27%, followed by France at 7,180.74%. Finland was at 1,716.04%, Tanzania at 1,550.75%, and Sri Lanka at 1,461.40%. Brazil, Cuba, Bangladesh and Romania were also above 500%. These values are striking, but the ratio itself explains why they can occur.
Domestic fertilizer production is the denominator. If production is very small relative to consumption, the percentage can become extremely large. A ratio of 20,000% means consumption is about 200 times the reported production level; it does not mean farms apply 200 times as much fertilizer per hectare as farms elsewhere. That distinction is essential whenever the denominator can approach zero.
The indicator description also notes that some chemical compounds counted in fertilizer statistics have other industrial uses. This can make consumption data an imperfect proxy for the amount actually available to crops. For that reason, extreme official values should not be clipped or declared erroneous merely because they look unusual. They are better treated as signals to inspect production, trade and product coverage in more detail.

Very low ratios do not mean farmers use little fertilizer
At the low end of the 2023 subset, Qatar was at 0.19%, Trinidad and Tobago at 0.97%, the United Arab Emirates at 1.76%, Jordan at 2.21%, and Israel at 2.39%. Oman was 2.80%, Morocco 5.34%, Saudi Arabia 7.14%, Lao PDR 7.14%, and Nigeria 12.51%. These values describe consumption relative to domestic production, not absolute fertilizer use.
A country with a large manufacturing base can consume a substantial quantity domestically and still have a low percentage if production is much larger. A country with little domestic production can show a high percentage even if its total consumption is modest. The ratio is therefore better suited to questions about the relationship between domestic supply and use than to questions about agronomic intensity or environmental pressure.
For comparisons of fertilizer use intensity, kilograms per hectare of arable land is more direct. For trade exposure, imports, exports and domestic production should be examined separately. For farm outcomes, crop yields, soil conditions and input prices matter. Using those measures alongside this ratio prevents a single denominator-driven statistic from carrying more interpretation than it can support.
Median and percentiles are more informative than the mean
The 2023 mean of 589.53% is not a good description of a typical economy because the two largest observations are thousands of percentage points above the center of the distribution. The median of 90.78% is more resistant to those extremes: half of the same-year observations are below it and half are above it.
The interquartile range adds context. The 25th percentile at 36.21% and the 75th percentile at 253.65% show where the middle 50% sits, while the 90th percentile at 655.19% marks the start of the most elevated upper tail. Reporting all of these values makes the shape of the data visible without removing legitimate outliers.
The same logic applies to map design. A standard linear legend from near zero to more than 20,000% would place a large majority of economies into a narrow part of the scale. Quantile classes or a logarithmic transformation can improve visibility, but they also make the legend less intuitive. For this indicator, a ranked log chart plus a same-year table communicates the denominator effect more transparently than a visually complete but temporally mixed world map.
What this ratio can and cannot tell you
The ratio can tell you whether calculated fertilizer consumption was smaller or larger than domestic fertilizer production in a given year, and by how much. It can highlight economies where domestic production is tiny relative to use and can identify candidates for a closer look at fertilizer trade. When observations share the same year, it also supports a descriptive comparison of supply structures across economies.
It cannot, by itself, tell you whether fertilizer use is excessive, whether farming is efficient, whether soils are being degraded, or whether a country is food secure. It also does not measure fertilizer affordability or the fiscal impact of fertilizer subsidies. Those questions require different indicators and often country-specific context.
The mixed-year coverage is a second limitation. Forty-three of the 115 latest observations predate 2023, so they should not be silently treated as current 2023 data. As additional values are reported, the same-year group may expand. Any future update should therefore recheck the observation year before recomputing rankings, percentiles or visual classes.
Source and a practical reading order
The underlying series is the World Bank indicator AG.CON.FERT.PT.ZS. The World Bank page identifies the Food and Agriculture Organization of the United Nations as the data source and shows a series spanning 1961–2023. The dataset used here contains 115 latest non-missing country observations; 72 are actually dated 2023 and form the same-year comparison in this article.
A practical reading order is: first check the observation year, then compare the ratio with the 100% parity line, then inspect whether an extreme value may be driven by a small production denominator. After that, bring in fertilizer use per hectare, production volumes and trade flows if the question requires more than a supply-to-use ratio. This approach preserves the official observations while avoiding the two most common mistakes: treating mixed years as one snapshot and treating a production ratio as a farm-use intensity measure.
Frequently Asked Questions
What does a fertilizer consumption-to-production ratio above 100% mean?
Within the indicator formula, calculated fertilizer consumption exceeded domestic production. With positive production, that is consistent with imports exceeding exports, but direct trade data are still needed to measure import dependence.
Why are only 72 economies used for the 2023 comparison?
The 115-row dataset contains each economy’s latest non-missing value, and the observation years range from 1967 to 2023. Only 72 rows are actually dated 2023, so they are the appropriate same-year subset.
Are ratios above 1,000% necessarily data errors?
No. A very small domestic-production denominator can produce extremely large percentages. The official value should be checked against production and trade data rather than automatically clipped or discarded.
Does this ratio show which countries apply the most fertilizer on farms?
No. It compares consumption with domestic production. Fertilizer use intensity is better measured with kilograms per hectare of arable land or other agronomic indicators.
