Manganese Deficiency
scouted June 30, 2023
- Background
- Soybeans were scouted at the V4 growth stage and widespread interveinal chlorosis was observed.
- Conclusion
- This issue was confirmed by an NC State Extension Specialist as a Manganese (Mn) Deficiency. Interveinal chlorosis of leaves, pale green color of the whole plant, and stunted growth can be associated with a manganese deficiency in soybeans. If an environment has been over applied with lime, a manganese deficiency may be observed as a result of limited availability at high pH. In this environment a foliar application of Mn was recommended to remedy this issue.
