Maximum of 2L/ac of any combination of micronutrients when mixed with a seed placed starter fertilizer.
Role of Iron
- Required for the formation of chlorophyll
- Essential for plant respiration, photosynthesis
- Required for symbiotic nitrogen fixation
- Energy transfer
Iron Soil Availability
- 12-22 ppm in soil test is medium amount
- Availability decrease with rising pH
- Poorly drained soils reduce iron uptake
