2022 Crop Acreage Report 

The June 30th USDA Crop Planting Report indicates that Iowa will plant 12.7 million acres of corn and 10.3 million acres of soybeans.  That is a 1.6% reduction in corn acres from a year ago, and a 2% increase in soybean acres from a year ago. Nationally, USDA reports that farmers have planted 89.9 million acres of corn, a drop of 3.7% from a year ago, and 88.3 million acres of soybeans, an increase of 1.3% from last year. 

Figure 1. Iowa Corn and Soybean Acreage 

Iowa corn acreage is declining by 102,727 acres per year, on average over the past decade.   

Iowa soybean acreage is increasing by 53,636 acres per year, on average, over the past decade (Figure 1). 


 Figure 2. U.S. Corn and Soybean Acreage 


U.S. corn acreage is declining by 353,764 acres per year, on average over the past decade, and U.S.  

U.S. Soybean acreage is increasing by 1 million acres per year, on average, during that time period. (Figure 2). 


Figure 3. 2022 Corn Planted Acres 

Iowa leads the nation in planted corn acres.  It is followed by Illinois, Nebraska, Minnesota and South Dakota. 

There are 23 states that plant 500,000 or more acres of corn. These states account for more than 95% of U.S. planted corn acres. 




Figure 4. 2022 Soybean Planted Acres 

Illinois is the leading state for soybean planted acres.  Iowa is in 2nd place, followed by Minnesota, Missouri, and North Dakota. There are 20 states with 500,000 or more planted acres of soybeans.  These states account for more than 97% of U.S. soybean acres. 


The June crop acreage report is a fairly accurate predictor of actual crop acreage for corn and soybeans in Iowa. Over the past 4 years, the June acreage number for Iowa corn has been between 97-99% of final corn acreage.  In recent years, corn acres harvested for grain have been between 92% and 96% of the June acreage number with the low year being 2020 when a large swath of Iowa was affected by the derecho. 

In recent years, Iowa’s final soybean acreage has been 101% to 102% of that reported in the June crop report. Harvested soybean acres in Iowa have fluctuated between 99% of the June acreage number and 101% of the June soybean acreage number. 

For the U.S., the June corn crop acreage has been between 98% and 101% of final acreage. Corn acreage harvested for grain in the U.S. averages 90% of the June corn acreage number with the recent low being 89% and the recent high being 92%.  Nationally, soybean harvested acreage has averaged 103% of the June soybean acreage number with the low being 101% of the June number and the high being 107% of the June number. In years when plantings are delayed, the final harvested acreage of soybeans tends to have the largest upward adjustments from the reported June soybean acreage figures.
