Fe 4.5%
Iron Supplementation for Chlorophyll and Energy Production
Fe 4.5% is a specially formulated liquid iron product designed for in-season supplementation to maintain healthy chlorophyll levels and strong photosynthetic performance. Iron is a vital micronutrient that supports chlorophyll synthesis, respiration, and enzyme activation—processes critical to energy production and overall plant metabolism. Consistent iron availability ensures efficient photosynthesis and sustained growth throughout the season.
Deficiencies in iron often manifest as interveinal chlorosis, where leaf tissue yellows between the veins due to reduced chlorophyll content. This condition lowers photosynthetic efficiency and crop yield potential. Fe 4.5% provides a fast-acting, highly available iron source that prevents and corrects these issues, ensuring vigorous, green foliage and optimal plant productivity. For best results, application timing should be guided by sap analysis to target plant demand precisely.
Key Benefits
- Prevents and corrects iron deficiencies — maintains healthy green foliage and chlorophyll production.
- Enhances photosynthesis and respiration — supports energy generation and metabolic activity.
- Promotes enzymatic functions — activates key enzymes that regulate plant growth and nutrient metabolism.
- Improves plant vigor and productivity — sustains healthy growth and yield potential throughout the season.
- Flexible application methods — suitable for foliar, sidedress, and fertigation programs.
Use Recommendations
Foliar: 1–2 quarts per acre when crops are 4–8 inches high or when deficiency symptoms appear. Repeat as needed.
Soil Application: ½–2 gallons per acre depending on crop, soil conditions, and application method.
For maintenance, apply ½–1 gallon Fe 4.5% per acre.
For severe deficiency, apply 2 gallons per acre.
Do not exceed recommended rates.
