Facing high fertilizer costs, farmers still struggle to use less
This is the fifth and story in a series, “The Price of Plenty.”
As a young boy in the late 1950s, Frank Glenn knew the soft, freshly-tilled brown dirt lining his family’s fields signaled the start of another planting season.
“Back when we were young buckaroos, we would plow and disc and get a crop of weeds to come up [and then] knock them down,” Glenn said.
Frank and his younger brother John would hop on the tractor and start pulling their blue plow through the fields in February and March. Then they would go back with a tiller and turn over the topsoil before planting corn, soybeans, wheat and oats.
Today, the Glenns are still running their family farm in Columbia, growing corn, soybeans and hay. But about 25 years ago they transitioned to a majority no-till operation, no longer digging up the first few inches of soil before planting. Their fields are now filled with big clumps of dirt and old roots from previous harvests.
Rob Myers, director of the University of Missouri Center for Regenerative Agriculture, said less than half of Missouri farmers are using a regenerative method such as cover crops, no-till or integrating crops and livestock. Cost is one of the factors holding farmers back, Myers said.
Farmers use fertilizer to build their soil’s fertility and help increase crop yields. But less than half of the nitrogen fertilizer applied is taken up by the crops. These excess nutrients wash into the Gulf of Mexico, creating a dead zone where fish and shrimp cannot live. But nutrient pollution is not just an environmental problem – it’s a business one.
Farmers are responsible for the cost of implementing alternative practices, and they bear the risk if it doesn’t work. Bruce Shryock, a corn, soybean and wheat farmer in Auxvasse, said farmers are stuck between science and the economy.
“If you spend more and then don’t make any more, then you’re in trouble,” Shryock said.
Farmer finances on the line
A report from the University of Missouri found that net farm income in the state is projected to decrease by 14% this year, while the U.S. Department of Agriculture anticipates national farm income to fall by a fifth. Meanwhile, farmers’ input costs have increased 55% since 2020.
Fertilizer accounts for about a third of these annual costs, and it now costs farmers nearly 73% more than it did in 2020. But farmers continue to buy it because it offers a good return on investment, said Ray Massey, a professor in MU’s College of Agriculture, Food and Natural Resources.
“The economics said that you can make more money if you have higher yields,” Massey said.
Farmers also must factor in other input costs like seed, pesticide, equipment and fuel. Crop revenue has increased but the prices for inputs have continued to rise, so their margins have stayed about the same, Frank Glenn said.
“It seems like they (the ag industry) don’t want farmers to make any money,” he said.
Some farmers coped with the price increases by cutting back on the amount of fertilizer they apply. Glenn said he and his brother went from applying 180 pounds an acre to 120 pounds last year. He said they were lucky crop prices were high or they might have not been able to survive the fertilizer price hike.
“Jesus, it makes you wanna puke,” his brother John Glenn said. “It’s so expensive.”
Promoting intentional fertilizer use
Because fertilizer is expensive, farmers want to get the most bang for their buck, said Andrea Rice, director of research, education, and outreach at the Missouri Fertilizer Control Board.
The agency enforces Missouri fertilizer laws, conducts nutrient research and helps farms implement alternative farming methods.
Rice said high costs and current profit margins discourage farmers from applying more than the recommended amount, noting that farmers lose money if the fertilizer washes off their fields.
Heavy rain or snow melt washes fertilizer into waterways, polluting water and creating toxic algae blooms in lakes and rivers. Ultimately, some of this pollution travels downstream to the Gulf of Mexico and creates a hypoxic area called the dead zone at the mouth of the Mississippi River where water oxygen levels plummet. Any wildlife in these areas must move or suffocate.
“The Gulf hypoxia situation – that’s not something that any farmer would want to cause,” Rice said. But she said the problem did not appear overnight and is going to take time to solve.
Farmers have several ways of measuring how much fertilizer they need to apply to their fields. This includes soil testing and looking at past harvests to compare their yield to the amount of fertilizer they applied.
The Glenns use a satellite to create a grid of their fields and take samples from each block on the grid. They can see how their soil structure varies and pinpoint the exact nutrients each block needs.
Miscalculations such as applying too much fertilizer, applying it on frozen ground or overwatering fields will increase the runoff potential.
Sarah Carden, a senior policy advocate at Farm Action, an advocacy group opposing corporate influence in agriculture, said the industry is set up to support conventional farming, which disincentivizes alternative practices.
It’s easier for conventional farmers to qualify for crop insurance, Carden said, but it gets harder when a farmer wants to decrease the amount of fertilizer they use.
“It becomes a lot riskier for a farmer to participate in alternative forms of production,” Carden said.
Making change happen
One method farmers can adopt to minimize the harmful effects of fertilizer is to plant cover crops, which help decrease erosion, hold moisture in the ground and reduce weeds.
Integrating cover crops was a learning experience for Shryock, the farmer from Auxvasse. In his first year planting cover crops, a wet spring spurred his rye to grow to about 8 feet tall. Getting that tall rye out of the field was a challenge, as it wrapped around his planter shaft and damaged the bearings on his equipment.
“I cussed it that first year,” he said.
Shryock has since learned to kill rye when it’s about 2 feet tall. He saw the benefits of cover crops after that first year as it helped his soil and decreased runoff.
Shryock also no-tills in addition to cover crops. These practices take more time, he said, but they’ve been worth it. He cut back on the amount of fuel he uses, but he still has to buy seed and pesticide and must spend time planting the cover crop. Shryock thinks more people would plant them if there was an incentive to help cover their costs.
Rice said education can help increase the adoption of cover crops, though some farmers are used to doing things the way they and their families always have.
She first advises new clients to do soil sampling. Then, she discusses the type of fertilizer they are using, the amount, application times and if they are using cover crops.
“If we take those things and we do a little bit at a time and we keep encouraging and keep educating over time, there will be a big impact,” Rice said.
The MU Center for Regenerative Agriculture has recently been awarded two grants: $25 million to offer financial incentives for farmers to implement regenerative practices and $10 million to research how to improve varieties of cover crops.
The grant will pay farmers to adopt grid sampling, cover crops and livestock grazing systems to decrease nitrogen runoff. It also will fund programs to help farmers learn about these methods and their benefits.
“It takes time to keep making changes and improvements in agriculture,” Myers said. “But I think we’re headed in the right direction with these practices.”
