- Seed germination processes
- Iron uptake regulation
Deficiency Symptoms:
Leaf tip necrosis, accumulation of toxic urea (rare deficiency)
📊 Micronutrient Availability vs Soil pH
💡 Key Insights
Most micronutrients are more available in slightly acidic soils (pH 6.0-6.8). Maintaining proper soil pH is crucial for optimal micronutrient uptake. Regular soil testing helps identify potential deficiencies before they impact plant health.
