Fertilizer is the quiet hinge between the energy market and the food market. The nitrogen in a bag of urea was, a few months earlier, natural gas — so a gas price shock in Europe and a calf shortage in Texas and a monsoon in India all meet, eventually, in the cost of growing a tonne of grain. We publish four Fertilizer Supply-Risk reports — Brazil, India, the US and the global producers — each a different window onto the same chain. This is what they track, why, and how to read the signal at the top of each one.
Start with the chemistry, because everything else follows from it. Nitrogen fertilizer is manufactured, not mined. Natural gas is reformed into ammonia, ammonia is processed into urea and other nitrogen products, and that nitrogen is spread on a field to grow a crop. Gas is roughly 70–90% of the cash cost of making ammonia — so the price of natural gas is, to a first approximation, the price of nitrogen fertilizer.
That single fact explains the chart below. We rebuild the cash cost of urea from the gas price in two regions — the US on cheap shale gas (Henry Hub) and Europe on imported gas (TTF) — and lay the world price on top. For most of the last six years the US has made urea for a fraction of Europe's cost. Then 2022 happened: Europe's gas spiked, its urea cash cost blew out above $1,400/t, marginal plants shut, and the world price followed. Today the wedge is back to its structural shape — US near $141/t, Europe near $389/t.
The chain is global, but every country sits on it differently. A pure importer feels a price shock; a low-cost producer barely notices the cost but worries about moving the product; a country with administered prices routes the shock into its government's budget instead. So rather than one blurred world average, we publish four reports — each tuned to how that region actually experiences fertilizer risk.
Each report leads with the same thing: a single Tightening / Neutral / Easing signal, built as a transparent sum of three or four components you can see line by line. We never hand you an opaque verdict — the point is to show the mechanism and let you weigh it. Here is where the four sit today.
Nitrogen is made all over the world wherever gas is cheap, so it is rarely a concentration problem. Potash is the opposite. It is mined, not made, and the deposits sit in a handful of places — so a few countries control most of world supply. That is why potash shows up as the binding risk in two of our four reports: the US single-sources ~90% of its potash from Canada, and on the global view potash exports are near-monopolistic.
This is the cross-report payoff. The Producers report measures the concentration structurally (a Herfindahl index of 0.70 for potash, where 1.0 is a monopoly); the US report measures the consequence for one buyer (that ~92% single-border dependence on Canada). The same fact, read from the supply side and the demand side — and a disruption the Producers report flags upstream is the cost shock the Brazil, India and US reports show downstream.
Every report's headline is a net score. The rules are the same across all four:
The number is never the whole story — the components beneath it are. A Neutral +1.0 built on “cheap producer cushion (−1) offsetting a single-source potash risk (+1)” is telling you something very different from a flat zero. Read the line items. And remember the cadence: these are monthly, fundamentals-driven reads — a risk state, not a buy or sell timing call. They are built to be read by you and, through our data layer, by an AI working on your behalf.
The series that drive these four reports — the self-computed gas→urea margins, import and export flows by origin, the potash concentration index, the Brazilian farmgate barter, India's landed-vs-subsidy gap, and the Mississippi barge read — are the data we publish, queryable directly and through our MCP layer for AI-assisted analysis. If you would rather run the supply-risk math yourself than take our read, that is exactly what the data is for.
