USDA vs Pro Farmer: What Are the Latest Yield Estimates Really Telling Us?
Corn yield estimates are suddenly a long way apart.
USDA is at 180.7 bushels per acre. Pro Farmer is at 173.2.
That 7.5-bushel difference has helped put some life back into the corn market—but for producers, the bigger question isn’t which estimate is right.
It’s whether this rally is giving you an opportunity you should be doing something with.
Corn: This Is Where the Biggest Question Mark Is
USDA’s August estimate put the national corn yield at 180.7 bushels per acre, with production estimated at roughly 16.0 billion bushels.
Then came the Pro Farmer Crop Tour.
After traveling across the Corn Belt and sampling fields, Pro Farmer estimated the national corn yield at 173.2 bushels per acre, with production at approximately 15.34 billion bushels.
That’s a pretty significant difference.
Based on those production estimates, we’re talking about a gap of roughly 660 million bushels.
And that’s exactly why the market reacted.
December corn rallied following the Pro Farmer estimate, closing Monday at $5.15½.
But here’s what you need to keep in the back of your mind:
A lower yield estimate does not automatically mean we have a shortage.
The U.S. is still looking at a historically large corn crop. The question is whether the crop is large enough to keep ending stocks comfortable once we account for demand.
That’s what the market will be trying to figure out as we move toward harvest.
Soybeans Tell a Different Story
Soybeans aren’t giving us the same bullish yield story.
USDA’s August report put the national soybean yield at 52.7 bushels per acre.
Pro Farmer came in slightly higher at 53.3 bushels per acre, with production estimated at approximately 4.57 billion bushels.
So while Pro Farmer is showing a significant production cut in corn compared with USDA, soybeans are telling a different story.
That matters because soybeans can rally on weather concerns, fund activity, outside markets, or strength in corn—but that doesn’t necessarily mean the soybean balance sheet has suddenly become tight.
So Which Estimate Should We Believe?
Neither one should be treated as the final answer.
USDA gives us an important starting point based on surveys and objective yield measurements. Pro Farmer gives us a field-level look at what scouts are seeing across the Corn Belt.
But neither one is a harvested yield.
The combine still gets the final say.
If USDA continues lowering corn yield, the balance sheet could tighten. If its 180.7-bushel estimate proves closer to reality, the market may have less of a supply problem than the recent rally suggests.
Over the next several weeks, we’ll be watching USDA’s numbers, early harvest results, and whether demand is strong enough to absorb what could still be a very large crop.
But there’s another yield estimate I think matters even more to your marketing decisions right now.
The Yield Estimate That Matters Most Might Be Your Own
Your own yield estimate should be one of the most important numbers in your marketing plan right now.
National yield helps determine the broader balance sheet.
Your farm-level yield helps determine how many bushels you actually have available to market.
If you’re expecting a better-than-average crop and still have a lot of bushels unpriced, this rally may mean something very different to you than it does to a producer with disappointing yield potential or a large percentage of the crop already sold.
That’s why there isn’t one marketing answer that fits every operation.
You have to know your numbers.
What Does This Mean for Grain Marketing?
This is where I think the conversation gets more important than the headline.
The market is giving us something that we haven’t had much of recently:
An opportunity to make a decision.
Corn has rallied as the market questions how big this crop really is.
That doesn’t mean you should sell everything.
It also doesn’t mean you should sit on everything waiting for $6.
It means you should be looking at your numbers.
Before Your Next Grain Sale, Know These Four Numbers
Your expected production
Your cost of production
The percentage of your crop already priced
Your profitability at today’s price
Then ask yourself: How many unpriced bushels am I comfortable carrying if the market gives these gains back?
And if today’s price gives me profitable opportunities, how much risk am I willing to take waiting for another 25 or 50 cents?
Those are more useful questions than trying to guess whether USDA or Pro Farmer will ultimately be right.
The Bottom Line
The latest yield estimates are giving the market something to talk about, especially in corn.
A 7.5-bushel-per-acre difference between USDA and Pro Farmer is significant.
But we’re still talking about estimates.
The combine will ultimately give us the answer.
The goal shouldn’t be to guess which estimate will be right.
The goal should be to have a marketing plan that works either way.
Take another look at your expected production, what you already have priced, and the profitability available today.
Because the market doesn’t have to give you the perfect price.
You need to make sure you’re prepared when it gives you a price worth taking.
