CHICAGO (Reuters) - A spike in bargain-basement crop sales by U.S. farmers needing to make room in storage bins for autumn harvests could boost profitability at grain handlers such as Archer-Daniels-Midland ( ADM ) and Bunge Global ( BG ).

Both companies, which trade and process soybeans and corn and benefit from geographic differences in supply, recently flagged slow farmer selling as a drag on second-quarter earnings.

Eight farmers in the key Midwestern crop-growing states of Iowa, Indiana, Illinois and Ohio told Reuters they are emptying storage bins of corn and soybeans harvested in 2023 after holding tight to supplies all year, as favorable weather for crop development finally dashes their hopes for higher prices.

Farmers earlier resisted sales as corn and soy futures prices sank to 2020 lows this year under pressure from large supplies.

Low prices are also driving some to use less crop chemicals, which could create a short-term pinch for agribusinesses like Corteva Inc ( CTVA ) and Syngenta, analysts said.

Increased sales should result in cheaper soybean ownership for ADM and Bunge, which process the crop into soybean oil and meal used for livestock feed, said Heather Jones, founder of Heather Jones Research.

More farmer selling also helps ADM and Bunge obtain supplies to use any excess manufacturing capacity, said Arun Sundaram, senior equity analyst at CFRA Research.

"Agribusinesses operate with a lot of overhead and have high fixed costs, so running manufacturing plants at or near capacity is key to preserving efficiencies and margins," he said.

'HAUL OF SHAME'

Growers, who are projected to suffer the largest ever year-to-year dollar drop in farm income in 2024, previously hoped that poor weather or geopolitical disruption would spark a rally.

"I'm throwing in the towel and making room for the new crop," said Ron Heck, a farmer in Perry, Iowa. Farmers start harvesting what the U.S. government expects to be the third largest corn crop and second largest soybean crop in September.

Heck said he recently hauled corn as fast as he could to a local plant owned by POET LLC, the world's largest ethanol producer, that offered to pay cash prices 42 cents per bushel, or about 10%, higher than futures.

Selling accelerated in the Midwest in late July as forecasts for hot, dry weather lifted futures to two-week highs, grain dealers said. The gains were short lived, as markets again collapsed to 2020 lows last week.

"We didn't get the hot, dry predicted weather, and there was no point in waiting for a weather rally," Heck said.

One grower in Illinois described farmers taking grain to local facilities for sale as the "haul of shame" because they should have sold earlier when prices were higher.

SELLING AT A LOSS

Justin Campbell, who farms outside Terre Haute, Indiana, is among those who booked sales last week as corn prices declined.

"I thought, 'We haven't found a bottom yet in prices,' so I wanted to get some of it priced," Campbell said.

Another Indiana farmer, who requested anonymity because he does not want neighbors to know about his sales, said he recently finished selling last year's corn to an ADM elevator for $3.54 per bushel, below his cost of production. He needed cash to make a payment that was coming due on an equipment loan.

Bunge, the world's largest oilseed processor, expects more farmer sales after its profit margins suffered in the April-June quarter from slow selling in North and South America, CEO Greg Heckman said last week. Bunge raised its full-year outlook, citing improving processing margins, following a 56% decline in adjusted second-quarter agribusiness earnings from a year earlier.

"The weather, it looks good," Heckman told analysts on an earnings call. "I think as you see that North American crop develop, we'll see some more marketing there."

Without making much money from farming, some growers said they are buying less fungicide, insecticide, fertilizer and equipment.

Chris Gibbs, who farms about 375 acres in Ohio, said he was not going to buy and pay for fungicide to be applied across all his fields to prevent plant disease as he normally does.

"I'm going back to walking the beans and corn rows, looking for problems in the field and only treating areas that absolutely need the help," Gibbs said.

Illinois farmer Dave Kestel said he is spraying fungicide on less than half his corn fields, cutting his use of a Corteva ( CTVA ) product called Aproach. Corteva ( CTVA ) on Wednesday cut its annual sales and operating earnings forecasts due to tighter farmer margins.

Still, farmers tend to pay up for seeds that promise to produce hefty yields, said Seth Goldstein, strategist at Morningstar Research Services. And deciding to cut back on chemicals can be tricky because growers want to produce big harvests to make the most money they can at low prices.

"Even in a down market, you still have to protect the crop," said Kristen Owen, executive director of equity research at Oppenheimer & Co.
