Citrus trees—whether oranges, lemons, limes, or mandarins—demand consistent and balanced nutrition throughout their lifecycle. Applying citrus fertilizer effectively can significantly boost yield, fruit quality, and resistance to disease. In this comprehensive guide, you’ll learn how to prepare your soil, apply fertilizer properly, and ensure your citrus trees receive optimal nutrition. Whether you’re a commercial grower or a backyard enthusiast, the right citrus fertilizer strategy can transform your harves
Preparing the Soil Before Applying Citrus Fertilizer
Before applying any citrus fertilizer, proper soil preparation is essential for nutrient uptake. Citrus trees prefer slightly acidic to neutral soil (pH 6.0–7.5), rich in organic matter and well-drained.
Start with a Soil Test A comprehensive soil test will help determine existing nutrient levels and deficiencies. Look for levels of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), and micronutrients like boron (B), zinc (Zn), and iron (Fe).
Recommended Preparations Before Fertilization Include:
Loosening the Soil: Improves aeration and root penetration.
Amending Organic Matter: Incorporate compost or organic fertilizer like Ugarit 10-0-5+70% Organic Matter (rich in humic and fulvic acids).
pH Adjustment: Add lime to raise pH or sulfur (e.g., SULPHOMIN, which provides 15% SO? and 45% N) to lower it.
Proper soil preparation ensures your citrus fertilizer—whether granular or liquid—functions at its full potential.
Fertigation: Ideal for orchards with drip or micro-sprinkler systems.
Foliar Spray: Used for quick correction of micronutrient deficiencies with products like SULFOMIX, which contains Fe, Zn, Mn, Cu, and B.
Soil Drench: Apply around the root zone for deep absorption.
Pro Tip: Use calibrated equipment to ensure precise delivery, especially when using concentrated formulas like Ugarit DKP (33% P?O?, 44% K?O) or Super DKP.
Post-fertilization care ensures nutrient absorption and minimizes environmental loss. Follow these practical steps to get the best results from your citrus fertilizer program.
After Fertilization, Ensure the Following:
Irrigation: Water immediately after applying granular fertilizers to dissolve nutrients and prevent runoff.
Mulching: Apply organic mulch to retain soil moisture and enhance microbial activity.
Weed Control: Remove weeds that compete for nutrients, particularly near Zone 2 and 3.
Monitor Leaf Color: Yellowing may indicate deficiencies; apply micronutrient-rich sprays such as SULFOMIXor Ugarit Beet for balanced trace elements.
If using fertigation, always flush irrigation lines to prevent clogging from residue, especially after concentrated phosphorus applications like Phosphoric Acid 85% w/v or Ugarit 0-52-34.
Bonus: Micronutrient Management in Citrus Fertilizer Programs
Citrus trees are particularly sensitive to micronutrient imbalances. To optimize yield and quality:
Zinc & Manganese: Critical for chlorophyll formation. Use Ugarit Grapes (Zn, Mn, Mg) as foliar spray in spring.
Boron: Improves fruit set and reduces cracking. Use SULFOMIXor CALCIMAGwhen leaf analysis shows deficiencies.
Effective use of citrus fertilizer requires understanding soil conditions, nutrient timing, application methods, and tree physiology. By implementing a balanced fertilization strategy using scientifically formulated products like Yarafert and Ugarit, growers can maximize citrus yield, fruit quality, and tree longevity.
