As climate change threatens farming, incentives for cover crops could help

Once a farmer understands how ecosystems function, planting cover crops is an obvious choice. At least, that’s what North Dakota farmer Gabe Brown believes. For nearly three decades, Brown has been planting his cash crops (barley, oats, wheat, rye, and others) alongside cover crops—plants that are not for sale but instead are planted among cash crops to help retain water, prevent erosion, and increase soil fertility.

“The reason we made the decision is simple—it’s profitable,” said Brown. Since planting cover crops, Brown’s farm has saved a fortune on fertilizer and water, and Brown said he has seen an increase in yield, too.

But in addition to boosting some farms’ profits, many climate and agriculture experts say that cover crops may help farms withstand the effects of weather extremes driven by climate change. As crops across the country suffer dramatic losses, less than a quarter of US farms currently use cover crops, leading some to call for federal farm programs to incentivize the practice more strongly. Yet other experts are less enthusiastic about cover crops’ potential, saying bigger solutions are needed to transform the farming system as climate change advances.

Farmer safety net growing more costly as climate changes

As cool weather sets in to the US Midwest, much of the farm state of Iowa is suffering from moderate to severe drought, but for farmer Brent Drey, another worrisome weather trend is also top of mind: Over the past few decades, the Drey family farm has noticed an uptick in rainfall, which often comes down so hard and fast that the moisture actually does more harm than good.

“There are times, especially in the spring, where it can dump three or four inches in a matter of an hour or two,” Drey said. “That really makes a mess for any farmer.”

Drey Farms, which grows 3,000 acres of mostly corn and soybeans near Sac City, Iowa, has sometimes lost production due to excess moisture, according to Drey. Flooding, heavy rains and excess snow melt can complicate planting, and drown out or sicken maturing crops as wet conditions lead to elevated levels of mold, fungus, and toxins.

For Drey and other farmers who suffer production losses due to excess moisture, the US Department of Agriculture (USDA) has long offered a crop insurance program to cover their losses.
