March 2, 2022 | Joseph Hopper

The United States Department of Agriculture (USDA) National Agricultural Statistics Service (NASS) released their 2021 soybean county estimates for Iowa on Thursday. According to the data, Iowa’s average soybean yield of 62 bu/acre narrowly tops the previous all-time record of 60 bu/acre set in 2016 and blows away last year’s state average of 53 bu/acre. Fifty-two of Iowa’s counties averaged at least 60 bu/acre soybean yields.

Grant Kimberley, Iowa Soybean Association (ISA) Sr. Director of Market Development, says as the demand for soybeans continues to increase domestically and internationally, Iowa is well positioned to continue its role as a supplier of high quality soybeans.

“This record state yield shows what is possible when you layer the improvements in genetics, farmer practices and just-in-time rainfall,” says Kimberley.
