James Hepp is sick of excuses.

The 36-year-old farmer manages about 1,600 acres of corn, soy, and small grains in northern Iowa. He keeps a close eye on his bottom line and says he wants to build a business that his three young children would be foolish not to join. For Hepp, a first-generation farmer, that means doing things differently from his neighbors.

In an effort to preserve soil health, he tills only narrow strips of land, leaving much of his field undisturbed. Hepp also avoids applying nitrogen fertilizer when he’s not growing crops.

At first, Hepp’s approach to farming focused on cutting costs. It let him make fewer passes with the tractor, saving money by using less diesel, herbicides, and fertilizer. The benefits for soil and water quality were a bonus.

“We’re doing this and it works. Like, what do you mean that you can’t afford to do it?”

But after more than a decade of hearing government agencies and ag commodity groups in Iowa urge farmers to fall in line with the state’s voluntary Nutrient Reduction Strategy and adopt conservation practices that could limit the nitrogen and phosphorus runoff fouling waterways, Hepp is fed up with inaction.

“You know, the Nutrient Reduction Strategy has been around for what, 13 years now?” said Hepp, often held up as a role model for his runoff-reducing efforts. “If you’re not doing it now, I don’t know what’s going to make you do it besides regulation.”

Hepp represents one-third of the “Lobe Rangers,” a trio of corn and soy growers in Iowa’s flat and fertile Des Moines Lobe who have taken to social media to highlight the enormous gap between the conservation goals outlined in Iowa’s strategy for nutrient loss and the actual adoption of conservation practices on cropland. Fifth-generation farmers Matthew Bormann and Zack Smith round out the squad.

Bormann, Hepp and Smith are hardly the first Iowans to call for policies that target the environmental footprint of a relatively unregulated industry. Regulation has been a rallying cry in the last year for environmental groups, politicians and citizens who fear the state’s poor water quality could be linked to its rising cancer rates.

But as award-winning farmers and former county Farm Bureau board members who’ve made a living growing thousands of acres of Iowa’s two biggest commodity crops, Bormann, Hepp, and Smith represent a different demographic in the reform........
