You have to wonder about the folks who tell developing nations not to use or subsidize fertilizer as a way of ending famines.

Malawi hovered for years at the brink of famine. After a disastrous corn harvest in 2005, almost five million of its 13 million people needed emergency food aid.

But this year, a nation that has perennially extended a begging bowl to the world is instead feeding its hungry neighbors. It is selling more corn to the World Food Program of the United Nations than any other country in southern Africa and is exporting hundreds of thousands of tons of corn to Zimbabwe.

In Malawi itself, the prevalence of acute child hunger has fallen sharply. In October, the United Nations Children’s Fund sent three tons of powdered milk, stockpiled here to treat severely malnourished children, to Uganda instead. “We will not be able to use it!” Juan Ortiz-Iruri, Unicef’s deputy representative in Malawi, said jubilantly.

Farmers explain Malawi’s extraordinary turnaround — one with broad implications for hunger-fighting methods across Africa — with one word: fertilizer.

Over the past 20 years, the World Bank and some rich nations Malawi depends on for aid have periodically pressed this small, landlocked country to adhere to free market policies and cut back or eliminate fertilizer subsidies, even as the United States and Europe extensively subsidized their own farmers. But after the 2005 harvest, the worst in a decade, Bingu wa Mutharika, Malawi’s newly elected president, decided to follow what the West practiced, not what it preached.

Stung by the humiliation of pleading for charity, he led the way to reinstating and deepening fertilizer subsidies despite a skeptical reception from the United States and Britain. Malawi’s soil, like that across sub-Saharan Africa, is gravely depleted, and many, if not most, of its farmers are too poor to afford fertilizer at market prices.

“As long as I’m president, I don’t want to be going to other capitals begging for food,” Mr. Mutharika declared. Patrick Kabambe, the senior civil servant in the Agriculture Ministry, said the president told his advisers, “Our people are poor because they lack the resources to use the soil and the water we have.”

Good grief! We in America make the great Midwestern agricultural zone explode with food each year through the use of fertilizers. In Israel, the desert has bloomed for the same reason. Why the heck tell developing nations -- nations where people are starving -- not to use the methods that we know work for us?

Am I for a free market? You bet I am. But in a case like Malawi, where the choice is between a little socialism and a lot of starvation, I fall firmly on the side of ensuring that people have enough to eat. It is time for other nations to follow the example set by this formerly starving African nation -- and for those who encourage a different path to question their own wisdom and motivations.
