scouted July 11, 2024
- Background
- Soybeans were scouted at the V9 growth stage and brown/yellow discoloration of leaves and stunted plants were observed in patches areas across the field.
- Conclusion
- This issue was confirmed by an NC State Extension Specialist as Zinc Toxicity following review of soil test reports. The application of sludge aided in the accumulation of metals like zinc, which led to these symptoms. In most instances, there are limited remedial options for this season.
