An MFA agronomy column reviewed 2023 crop results, with corn yields from 100 to nearly 300 bushels per acre and test weights down. Soybean yields were mostly in the mid-to-upper 50s, aided by August rains.
Early charcoal rot also appeared after dry conditions in spring.
Mixed yields and some disease losses point to a variable supply picture, with limited direct price impact.
