Can the world feed itself?
Historic fertilizer crunch threatens food security
For the first time ever, farmers the world over — all at the same time — are testing the limits of how little chemical fertilizer they can apply without devastating their yields come harvest time. Early predictions are bleak.
In Brazil, the world’s biggest soybean producer, a 20% cut in potash use could bring a 14% drop in yields, according to industry consultancy MB Agro. In Costa Rica, a coffee cooperative representing 1,200 small producers sees output falling as much as 15% next year if the farmers miss even one-third of normal application. In West Africa, falling fertilizer use will shrink this year’s rice and corn harvest by a third, according to the International Fertilizer Development Center, a food security non-profit group.
“Probably farmers will grow
enough to feed themselves. But the question is what they will have to feed the cities,” said Patrice Annequin, a senior fertilizer market specialist for IFDC based in Ivory Coast. When you add increased hunger across West Africa on top of existing risks like terrorism, “this is absolutely dangerous for many governments in our region.”
For the billions of people around the world who don’t work in agriculture, the global shortage of affordable fertilizer likely reads like a distant problem. In truth, it will leave no household unscathed. In even the leastdisruptive scenario, soaring prices for synthetic nutrients will result in lower crop yields and higher grocery-store prices for everything from milk to beef to packaged foods for months or even years to come across the developed world. And in developing economies already facing high levels of food insecurity? Lower fertilizer use risks engendering malnutrition, political unrest and, ultimately, the otherwise avoidable loss of human life.
“I’m reducing the use of fertilizer in this crop cycle. I can’t afford such stratospheric prices,” Marcelo Cudia,
61, a farmer in the Philippines’ rice-producing region of Central Luzon, said outside the patch of land he’s been cultivating for the last 13 years. About 12,000 miles away, Brazilian soybean farmer Napoleão Rutilli is facing the same tough choices. “If fertilizers are expensive, we’ll use less fertilizers. If we’ll use less, we’ll produce less,” said the second-generation farmer, 33. “Food prices will increase and everyone will suffer.”
Why are fertilizer prices going up?
Commercial farmers rely on a combination of three key nutrients — nitrogen, phosphorus and potassium — to fuel their harvests. Those inputs have always been key, but it was only about a century ago that humanity learned to manufacture mass-produced ammonia-based nutrients. The discovery of the Haber-bosch method in the early 1900s, which is still used to make fertilizer today, has allowed farmers to vastly increase their yields. The agriculture industry has since come to depend on — even hinge on — man-made fertilizer. Although soil’s needs are different region to region, the general trend is pretty undisputed: More fertilizer use brings more food production.
But as costs for synthetic nutrients have skyrocketed — in North America, one gauge of prices is nearly triple where it was at the start of the pandemic — farmers have had to start paring back use, sometimes dramatically. That’s put the world in uncharted territory.
“Fertilizer prices are up an average of 70% from last year,” said Timothy Njagi, a researcher at the Tegemeo Institute of Agricultural Policy and Development in Kenya, referring to prices in the country. “The fertilizer is available locally, but it’s out of reach for the majority of farmers. Worse, many farmers know that they cannot recover these costs.”
Prices have been climbing for more than a year for a host of reasons: runaway pricing for natural gas, the main feedstock for much of the world’s nitrogen fertilizer; sanctions on a major Belarusian potash producer; backto-back late-summer storms on the U.S. Gulf Coast that temporarily shut-in production in the region; plus Covid-19 restrictions that have disrupted every global supply chain, including chemicals.
That tightening in the physical fertilizer market has galvanized China, the largest phosphate producer, to restrict outgoing shipments in order to build up a stockpile at home, further exacerbating the global shortage. Add Russia’s invasion of Ukraine, which effectively cut off nearly a fifth of the world’s nutrient exports, and the fertilizer industry and its pricing mechanisms are arguably more broken than ever before.
“Fertilizer sales are very, very low, to the point of desperately low, and this should be traditionally the busiest time of the year,” said Jo Gilbertson, head of fertilizer at Agricultural Industries Confederation, a U.k.based trade association. “The seeds of the problem are being sown now.”
How will lower fertilizer use hit output?
“My biggest concern is that we end up with a very severe shortage of food in certain areas of the world,” Tony Will, the chief executive of the world’s largest nitrogen fertilizer company CF Industries Holdings Inc., said in a March interview.
In the Philippines, urea — a key nitrogenous fertilizer — is now about 3,000 pesos (about $57) per bag, and even more when transported to the fifelds. That’s more than three times the price at this time last year, said Roger Navarro, president of Philippine Maize Federation Inc. “Farmers will tend to decrease the usual fertilizer dose of their crop and that will lessen the production,” he said, forecasting a 10% drop in yields. “It is rather sad, but this is reality.”
The yield outlook is even worse elsewhere. Peru’s agricultural industry is facing a defifcit of 180,000 metric tons of urea, and output of staples such as rice, potatoes and corn could tumble as much as 40% unless more fertilizer becomes available. The International Rice Research Institute predicted crop yields could drop 10% in the next season, meaning there’ll be 36 million fewer tons of rice — enough to feed 500 million people. In Subsaharan Africa, food production could drop by about 30 million tons in 2022, equivalent to the food requirement of 100 million people, the IFDC said in December — and that forecast was made before the war in Ukraine pushed prices to new records this spring.
There’s also a growing concern less fertilizer use will result in lower-quality crops. Just ask Gary Millershaski, who farms nearly 4,000 acres of wheat and roughly 3,000 acres of corn and sorghum in southwest Kansas. Also chairman of the Kansas Wheat Commission, Millershaski said the commission’s “biggest fear” this spring is that farmers may have skipped applying nitrogen as the wheat emerged from winter dormancy several weeks ago. If they did, it could hurt protein content of the grain and result in a “lower class of wheat.”
With nearly half of U.S. wheat exported to other countries, that’s a problem that will impact consumers the world over. The harvesting of hard red winter wheat, the most widely grown class in the U.S. and the grain that’s used to make all-purpose flour, will begin in June.
