Manganese Deficiency

scouted June 30, 2023

Soybeans were scouted at the V4 growth stage and widespread interveinal chlorosis was observed.
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.
