This Ancient Practice Could Help Revitalize America’s Corn Belt

Farmers can build more resilient farmlands by growing trees alongside crops and livestock, a technique called “agroforestry.”

Drive through rural Minnesota in high summer and you’ll take in a view that dominates nearly the entire US Midwest: an emerald sea of ripening corn and soybeans. But on a small operation called Salvatierra, 40 minutes south of Minneapolis, Reginaldo Haslett-Marroquin is trying something different. When he bought the land in 2020, this 18-acre patch had been devoted for decades to the region’s most prevalent crops. The soil was so depleted, Haslett-Marroquin says, he thought of it as a “corn and soybean desert.” Soon after, he applied 13 tons of compost, sowed a mix of prairie grasses and rye, and planted 8,200 hazelnut saplings.

While he won’t reap a nut harvest until 2025, the farmer and Guatemalan immigrant doesn’t have to wait to make money from the land. He also runs flocks of chickens in narrow grassy paddocks between the rows of the fledging trees, where they hunt for insects and also munch on feed made from organic corn and soybeans, which they transform into manure that fertilizes the trees and forage.

Salvatierra is the latest addition to Tree-Range Farms, a cooperative network of 19 poultry farms cofounded in 2022 by Haslett-Marroquin. Chickens evolved from birds known as junglefowl in the forests of South Asia, he notes, and the co-op’s goal is to conjure that jungle-like habitat. Chickens crave shade and fear open spaces; trees shelter them from weather and hide them from predators. In 2021, Haslett-Marroquin’s nonprofit, Regenerative Agriculture Alliance, purchased a poultry slaughterhouse just south of the Minnesota border in Stacyville, Iowa, where farms in the Tree-Range network process their birds. You can find the meat in natural-food stores from the Twin Cities area to northern Iowa.

By combining food-bearing trees and shrubs with poultry production, Haslett-Marroquin and his peers are practicing what is known as agroforestry—an ancient practice that intertwines annual and perennial agriculture. Other forms include alley cropping, in which annual crops including grains, legumes, and vegetables grow between rows of food-bearing trees, and silvopasture, which features cattle munching grass between the rows.

“With just a couple feet of soil standing between prosperity and desolation, civilizations that plow through their soil vanish.”
