Historical Planted Acre Changes for Corn and Soybeans | an interview with Gray Schnitkey

Friday, March 31, 2017, USDA will release the Prospective Plantings report. The survey of U.S. farmers will estimate how many acres of corn and soybeans will be sown this spring. University of Illinois Agricultural Economist Gary Schnitkey talks with Todd Gleason about the historical changes in planted acres.

At its annual Agricultural Outlook Conference in February, USDA projected that planted acres of corn would decrease from 94.0 million acres in 2016 to 90.0 million in 2017, a decrease of 4 million planted acres. At the same time, soybean acres are projected to increase from 83.4 million acres in 2016 to 88.0 million in 2017, an increase of by 4.6 million acres. Herein, we evaluate historical changes in acres across counties, thereby providing perspective on where likely 2017 acreage changes may occur.

U.S. Planted Acres

In 2016, planted acres to corn in the United States was 94.0 million acres (see Figure 1). This acreage level was the third highest number of planted acres since 2000, only being exceeded by 2012 (97.3 million acres) and 2013 (95.4 million acres). The 2017 projection of 90 million acres would be a 4.0 million acre decrease from the 2016 level. Plantings of 90.0 million acres would be about the same level as occurred in 2014 (90.5 million acres) and would be below the average planting for the last ten years.



In 2016, planted acres to soybeans was 83.4 million acres, the highest amount ever planted in the United States. Before 2014, planted acres to soybeans never exceeded 80 million acres (see Figure 1). Planted acres exceeded 80 million acres in each year since 2014: 83.2 million acres in 2014, 82.6 million in 2015, and 83.4 million in 2016.

In the following maps, acreage changes from 2011 to 2016 will be shown. In 2011, U.S. corn acres were 91.9 million, 1.9 million acres higher than in 2016. Reversing the corn acre increases during this five year period would go part way to reaching the decreases projected for 2017. The soybean acreage increase from 2011 to 2016 of 8.4 million represents twice the change projected from 2016 to 2017.
Corn Acre Changes

Figure 2 shows a map color coded to give changes in acres from 2011 to 2016. Counties colored blue had increases in acres, counties coded in orange had decreases in acres. Those counties that are yellow had essentially the same acres in 2016 as they did in 2011.



Several areas had pronounced increases. In particular, the northern Great Plains had sizeable increases. Between 2011 and 2016, North Dakota increased acres by 1.2 million, South Dakota by .4 million, and Minnesota by .4 million. Another area of sizable increase was Texas, with the planting .9 million more acres in 2016 than in 2011. Counties along the Mississippi River, especially in Arkansas, increased acres as well.

There were areas of notable decreases as well. Sizable decreases in corn acres occurred in Illinois. Between 2011 and 2016, planted acres in decreased by 1.0 million in Illinois. Indiana and Iowa had modest decreases as well.

Soybean Acre Changes

Figure 3 shows a map with planted acre changes for soybeans. Similar to corn, soybean acres increased in the upper Great Plans. Planted acres increased by 2.0 million acres in North Dakota, 1.1 million acres in South Dakota, and .5 million acres in Minnesota.



Other areas of significant increase were Illinois with a 1.1 million acres increase in planted soybeans. Planted acres also increased along the Mississippi River, parts of Kentucky and Tennessee, as well as areas in North and South Carolina.

Perspective on Changes for 2017

Areas with large acreage changes in the past likely will contribute in a significant way to acre changes from 2016 to 2017. These areas include the upper Great Plans, Texas, and the corn belt.

It seems conceivable that total corn and soybean acres could continue to increase in the upper Great Plains in 2017. Much of the acreage increases of corn and soybeans between 2011 and 2016 came from acres previously planted to wheat. In 2017, wheat acres could continue to decrease, leading to increases in corn and soybean acres. Whether corn acres will decrease while soybean acres increase in this region is an open question. One event that could lead to acre decreases is higher incidence of prevented planting. Prevented plantings were low in 2016, leaving open the possibility of increases in prevented planting acres in 2017.

Texas could see acreage shifts away from corn. Cotton prices look favorable, and an increase in cotton acres could contribute to fewer acres in corn.

Illinois and the corn belt in general could see shifts from corn to soybeans. Returns from crop budget suggest soybeans will be more profitable than corn (farmdoc daily, December 6, 2016), suggesting a shift is possible.

While budgets suggest the possibility, acre shifts have been slow in coming. Perhaps the most likely area where a shift will occur is where corn acres exceed soybean acres by a considerable margin. Corn acres divided by soybean acres exceed 1.0 in many counties in southern Minnesota, Iowa, northern and central Illinois, and western Indiana (see Figure 4). Bringing these areas back closer to a 50% corn - 5% soybean rotation, indicated by 1.0 corn divided soybean value, could increase profits suggesting that switches are possible.



Summary

Areas that experienced large acre changes in the past likely will be the ones where acres changes occur in 2017. This suggests focus on the upper Great Plains, Texas, and Illinois and the corn belt more generally. Continued corn and soybean acreage increases in the upper Great Plains seem reasonable to expect, except if prevented planting acres increase significantly. Texas could experience reduced corn acres. Budgets suggest switches to more soybeans from corn in the Midwest, although this is the case in previous years. Further indications of planting attentions will be received with the release of NASS’s Prospective Plantings report on March 31.

USDA March 31 Report Day React - interview with Darrel Good

Prospective Plantings

Grain Stocks

Grain Stocks & Prospective Plantings Reports Previews

USDA will officially kick off the new year for the spring planted crops when it releases two reports on the last day of the month.

The Grain Stocks and Prospective Plantings reports will be released March 31st. Darrel Good says both will help set the tone of the trade for corn and soybeans going forward.

Quote Summary - The Stocks report will be modestly important as it always is for corn. It will give us a reading on how fast we are feeding last year’s crop, but the real information will be in the Prospective Plantings report. It can be a mixed bag. This is because we all know actual plantings deviate from intentions. Certainly, though, when we see the March survey and what farmers are planning this year, it will provide a lot of information about the potential size of the upcoming crops.

The Prospective Plantings report is set up to be very interesting. More than a few acres around the United States need a new home on the spreadsheets. For instance, last fall farmers seeded about 2.8 million fewer acres of winter wheat than they did the previous year. When you couple those acres with what most expect to be fewer Prevent Plant acres, it creates an interesting combination says the University of Illinois agricultural economist.

Quote Summary - On the surface this says, “We’ll have more acres available than we had last year”. What the intentions report will give us a hint at is whether producers are thinking about leaving some acreage idle in 2016 because of the generally low commodity prices. For example, will the winter wheat acres that didn’t get planted go to fallow, or to annual pasture, or will they go to sorghum or an oilseed. Will we see some of the so called fringe areas leave some acreage idled as the numbers would suggest we’ve seen in the past when prices are low. So, that big picture question will be most important in the March plantings report.

Again, the reports will be released March 31st. Last year there were 6.7 million acres of Prevent Plant. That’s on the high side because of the heavy 2015 rainfall. Darrel Good expects this year to be something closer to 3 million acres. And, when you round up to 3 million fewer acres of winter wheat, you get about 6 million float acres that need a home this year either idled, or planted.

The Final Days of the USDA Report Data

Tuesday the Department of Agriculture will release one of its most anticipated reports of the year. It began collecting data from farmers at the beginning of this month. The crop acreage data is compiled, encrypted and transferred to Washington, D.C.

USDA contacts more than 80,000 farmers across the United States in March. It asks them a series of questions. One in the series is about which crops and how many acres of each they expect to plant this season. The agency sends all those farmers a letter to do this. Those not responding get a phone call, and then if they still don’t respond receive a face-to-face visit. The collection was completed Wednesday March 18th. Last Friday the Illinois and Missouri National Agricultural Statistics Service staffs, if the schedule went as Mark Schleusener expected, should have been reviewing the information.

Quote Summary - The last few days before publication there is an analysis period. Friday morning we are going to look at a balance sheet. We’ll add up all the corn, soybeans, wheat, hay, etcetera, and CRP. In Illinois the total is pretty constant across years with the mix of crop acres changing from one year to the next. So, we’ll make estimates on acreage in each, add them up, and compare it to previous years to see if the sum of the parts makes sense. We’ll do that Friday morning and then submit our estimates in an encrypted file to our Washington, D.C. headquarters. There will be more analysis done under secure conditions and the report comes out March 31.

This analysis is done by National Agricultural Statistic Service staff. Schleusener says the staff is primarily gifted in two area; statistics and agriculture. And he says the sum of those two qualifications is what’s required to do a good job for NASS. Schleusener serves at the NASS Illinois State Statistician.

Quote Summary - So, we are looking at what the number shows. What comes out of the computer, and how that compares to previous surveys and other factors. For instance, this balance sheet approach is a way to make sure we don’t go off-the-rails by being a little bit too high on each crop and a lot too high overall. The balance sheet makes sure we don’t go in that direction.

It gives the analysts a chance to see errors before the Prospective Plantings figures are reported up the chain or out the door. The Prospective Plantings report will be released in Washington, D.C. at noon eastern time Tuesday March 31, 2015.

How USDA NASS Counts Acres

USDA has just wrapped up its survey of more than 80,000 U.S. farmers. The agency uses the information to develop the March 31st acreage forecast.

In the spring USDA’s National Agricultural Statistics Service division contacts farmers in hopes of learning how much of each crop they expect to plant. The agency contacts farmers across the United States. Corn and soybean farmers are of particular interest. This year more than 4000 Kansas farmers were tapped, along with around 3700 in Nebraska and about 3000 in each of the Dakotas, Iowa, and Illinois. Another 2000 farmers each were contacted in Indiana and Ohio.

Quote Summary - Our goal is to make sure we are measuring small, medium, and large farms. So, we use what’s called a stratified sample.

That’s NASS Illinois State Statistician Mark Schleusener.

Quote Summary - That is a fancy way of saying for the biggest farms, we are going to talk to all of them; for the large, but not biggest we will talk with one out of three of those and for the medium, maybe one out of ten; and for the smaller farms we might measure one out of twenty-five of those.

Each farmer surveyed is asked how many acres they operate. How much of that land they intend to plant to corn or soybeans, and how much might already be in wheat. They’re also asked about oats, sorghum, and hay. The response rate goal, and usually achievement, is an amazing eighty percent.

Quote Summary - Yes, our goal is an 80% response rate on all surveys and we use several methods of data collection. Every producer in the sample receives a letter with a planting intentions questionnaire. The letter also has instructions for reporting to a secure internet website. These are both inexpensive ways of gathering data. The people that do not respond will be called. If this doesn’t work then someone will make a farm visit for a face to face. Both these methods are more effective, in general, but also are more expensive.

The biggest problem NASS faces when taking the acreage survey is that farmers usually haven’t yet made all their planting decisions. The agency knows this and is satisfied with best estimates. The individual reports are confidential by law and the data collected is exempt from legal processes.

The data can be aggregated at the county, state, and national level. Computers flag any large acreage changes at the individual level so that an analyst can check for a data entry error or make a follow up call. The state statisticians review the total number of crop acres for any major changes - total crop acres generally remain constant - and then submit the estimates in an encrypted file to USDA NASS in Washington, D.C. There more analysis is done and the final report is produced for release March 31.
