Iron Deficiency Chlorosis was a common sight in the soybean fields of northwest Minnesota and eastern North Dakota this year. North Dakota State University has evaluated over 200 Roundup Ready and Xtend soybean varieties and 40-plus conventional and Liberty Link varieties for IDC tolerance. The test results are available online. Many varieties had very little chlorosis, but the top variety in the two plots is from REA Hybrids—RX0228. The North Dakota Soybean Council funded this research.
