Low Zinc in Maize: Causes, Symptoms, and Solutions
Causes:
- Low zinc in soils often results from high pH levels, excessive phosphorus, or poor organic matter content.
- Sandy soils or soils that are heavily eroded are particularly susceptible.
Symptoms:
- Stunted growth, chlorosis (yellowing) of young leaves, and interveinal necrosis.
- White stripes appear on the lower parts of the leaves, affecting the plant's overall vigor.
Solutions:
- Soil Testing: Regular soil testing can help identify zinc deficiencies early.
- Zinc Fertilization: Apply zinc sulfate or chelated zinc fertilizers to correct deficiencies. Foliar sprays can also be used as a quick remedy.
- Crop Rotation and Organic Matter: Incorporate organic matter to improve soil health and enhance zinc availability.
