DES MOINES, Iowa — Farm groups and some members of Congress from farm states are decrying proposed cuts to crop insurance and other safety net programs for farmers included in President Donald Trump’s budget.

The proposed cuts come even as farmers are facing their fourth straight year of falling income, and could particularly affect farm states such as Iowa, Kansas and Nebraska that helped Trump win the November election.

“Clearly, this budget fails agriculture and rural America,” American Farm Bureau Federation President Zippy Duvall said in a statement.

The proposed budget would cap the amount of money the U.S. government provides to help farmers pay insurance premiums and eliminate insurance coverage for lost revenue when crop prices and per-acre yields fall. That would reduce the federal insurance program’s budget by $28 billion over 10 years.

Trump has also proposed reducing subsidies to farmers, cutting those programs by $9 billion by decreasing the maximum income level from $900,000 to $500,000 for a farmer to be eligible. The budget would also cut 5,263 jobs at the U.S. Department of Agriculture, a 5.5 percent reduction in staff.

Farmers, economists and agriculture experts say it is important to support the agriculture sector, which makes up about 11 percent of U.S. employment, or about 21 million jobs, and contributes nearly $1 trillion to the nation’s domestic productivity.

“The strength of the agricultural economy has implications for rural America, but also for the larger U.S. economy,” Robert Johansson, the USDA’s chief economist, told senators last month.

Michigan Sen. Debbie Stabenow, the leading Democrat on the Senate Agriculture Committee, warned that the proposed cuts “would have a disproportionate impact on small towns across our country and leave those communities in crisis.”

But some people say there’s no need for farmers to worry just yet.

“What I’ve been telling farmers is let’s just relax a bit before we panic. It’s going to be hard for Trump to get anything done. That’s become really obvious,” said Brent Gloy, a former Purdue University agriculture economist.
