Editor's note: CNN Foreign Affairs Correspondent Jill Dougherty and National Security Producer Laurie Ure were given exclusive access as the Afghan and Pakistani agricultural ministers went to Iowa. See the report Monday on CNN's "The Situation Room" with Wolf Blitzer (5 to 7 p.m. ET) and on CNNi's "Connect the World".
Across the road from his cornfield in Colo, Iowa, family farmer Keith McKinney pulls out his cell phone and checks the latest market prices from the Chicago Board of Trade.
"Soybeans are up $3. Corn is $3.25 up. And I get that information three times a day."
Armed with that information, McKinney can sell his crops when he wants, locking in prices even before they're planted.
Watching him with keen interest is Afghan Agriculture Minister Mohammad Asef Rahimi. He's thinking of farmers back home.
