In soybeans, chloride is needed for osmotic regulation in plant cells. Deficiency symptoms are not clearly described but may include chlorosis and wilting of leaves in soybeans. Toxicity symptoms include leaf tip scorching, premature yellowing or bronzing of leaves, and leaf loss.
In soybeans, boron is needed for cell walls during cellular expansion and normal development of nitrogen-fixing root nodules. Overall, soybeans are rather insensitive to boron deficiency but very sensitive to toxicity, including scorching/necrosis on the leaf edges.
Would you believe that some growers are adding winter wheat to their rotation to improve soil health? A healthy functioning soil provides numerous local ecosystem benefits including improved water quality, flood and drought mitigation.
The decision to harvest as forage (hay or silage) or grain should be based on economics. However, the decision to not harvest soybeans as grain does need to be made as soon as possible to capture the forage value of drought-stressed soybeans.
