Many alfalfa fields in northeastern Indiana suffered serious winter injury. Statewide, alfalfa weevil damage was more common this year and control was difficult because of persistent spring rain. Timely forage seeding of perennial legumes and cool-season grasses this spring was not possible because of excessive rain. Continued rainfall has limited the ability to make hay on a timely fashion and forage quality will be compromised. A result of all of these concerns is that forage supplies in the Midwest USA will likely be reduced in 2019. Producers need to carefully consider all options to meet forage needs if winter injury and waterlogged soils reduced forage yield and quality.

Light green alfalfa in the background of the photo was adequate in all nutrients except S which was 0.14% – well below the critical level of 0.25%.
Now that alfalfa has broken winter dormancy, it is time to assess the wellbeing of the crop. It is important to scout the entire field and not just one location as differences in soil types can change conclusions made about alfalfa health.
