Krishikranti Iron Fe EDDHA 6% | Chelated Iron Fertilizer for Alkaline Soil

Krishikranti Iron Fe 6% EDDHA is a chelated iron micronutrient fertilizer that corrects and prevents iron deficiency (chlorosis) in crops. It contains 6% iron in a stable EDDHA-chelated form that stays plant-available even in alkaline and calcareous soils with pH up to 9.5. It is used in wheat, citrus, grapes, soybean, vegetables, and fruit trees where iron deficiency causes yellowing of leaves and reduced yield. Why Iron Deficiency Happens in Indian Soils Indian soils are not short of iron the problem is availability. In alkaline and calcareous soils (pH above 7.5), iron becomes insoluble. Roots cannot absorb it. The result is iron chlorosis: young leaves turn yellow while the veins stay green. This is one of the most common micronutrient disorders in Indian agriculture especially in the Indo-Gangetic plains, black cotton soils (Vertisols), and calcareous soils of Madhya Pradesh, Rajasthan, Gujarat, and Maharashtra. Regular iron fertilizers like ferrous sulfate fail in these soils. The iron reacts with soil calcium carbonate and precipitates before reaching the root. EDDHA chelation solves this the EDDHA molecule keeps iron protected in soil solution so the plant can absorb it. Product Technical Specifications Iron Content 6% (Fe) Chelate Type EDDHA Effective Soil pH 4.0 — 9.5 Form Water-Soluble Powder Colour Dark Red / Maroon Application Soil / Drip / Foliar The ortho-ortho EDDHA isomer is the most active and stable fraction in alkaline soils. Fe EDDHA is far more stable than EDTA (effective only up to pH 7) or DTPA (effective only up to pH 7.5). In soils with pH above 7.5, Fe EDDHA is the only chelated iron form that delivers reliable crop-available iron. Target Crops and Iron Deficiency Symptoms Crop Category Specific Crops Common Symptom of Iron Deficiency Fruit Trees Citrus (lemon, orange, mosambi), Apple, Mango, Guava, Pomegranate Interveinal chlorosis on young leaves; pale yellow new flush Vine Crops Grapes Bright yellow young leaves; poor fruit set; weak cane growth Field Crops Wheat, Soybean, Groundnut Yellow-green seedlings; stunted early growth; pale canopy Vegetables Tomato, Capsicum, Brinjal, Spinach, Cucumber, Peas Yellow new leaves; poor fruit development; low yield Paddy (Aerobic) Rice grown without continuous flooding Yellowing of young leaves; poor tillering; stunted growth Plantation Banana, Chilli, Coconut Yellow leaf tips; poor plant vigour; reduced fruit size Important: Iron chlorosis always appears first on new and young leaves. If older leaves are yellowing, the cause is likely nitrogen or magnesium deficiency not iron. Diagnose correctly before applying. Dose and Application Rate Doses below are based on standard EDDHA Fe 6% label recommendations. Always read the actual product label before use. Apply at the higher end if deficiency is severe or soil pH is above 8.5. Soil Application / Drip Fertigation Crop Method Dose per Acre Dose per Hectare Best Timing Wheat Fertigation / Soil drench 500–1,000 g 1,250–2,500 g Tillering to jointing stage Soybean Fertigation / Soil drench 500–1,000 g 1,250–2,500 g Vegetative growth stage (V2–V4) Groundnut Fertigation / Soil drench 500–1,000 g 1,250–2,500 g Pegging to pod fill stage Citrus (Lemon / Orange) Soil drench at drip zone 20–50 g/tree — Pre-flowering or at new flush Apple / Pear Soil drench at root zone 20–60 g/tree — Bud break to new leaf stage Mango / Guava Soil drench at drip zone 30–60 g/tree — At new flush emergence Grapes Drip fertigation 500–800 g 1,250–2,000 g Bud burst to pre-flowering Tomato / Capsicum Drip fertigation 500–800 g 1,250–2,000 g Vegetative + early fruiting stage Brinjal / Cucumber Fertigation / Soil drench 400–700 g 1,000–1,750 g Vegetative growth period Banana Drip fertigation 20–40 g/plant — Monthly during active growth General Vegetables Fertigation / Soil drench 400–800 g 1,000–2,000 g Vegetative growth period 🌿 Foliar Spray (Emergency / Curative Use) Crop Dose per Litre Water Water Volume per Acre Spray Timing Repeat All field crops 0.5–1 g / litre 150–200 litres Early morning; at first chlorosis symptom After 10–15 days if needed Vegetables 0.5–1 g / litre 150–200 litres At first yellowing of new leaves After 10–15 days if needed Fruit trees 1 g / litre As required per canopy New leaf / flush emergence stage After 15 days if needed Soil application is always preferred. Iron is not highly mobile within the plant foliar iron corrects the sprayed leaves but does not redistribute well to new growth. Use foliar spray for quick emergency response, then follow up with soil application. How to Apply Fe EDDHA 6% Dissolve in clean water. Fe EDDHA is fully water-soluble and dissolves quickly. Use clean, non-hard water for best results. Do not mix with concentrated phosphate solutions. Drip / Fertigation (recommended). Inject the dissolved solution through your drip system directly to the root zone. This is the most efficient method zero wastage, maximum root contact. Soil drench (for trees). Mix in 20–30 litres of water and pour around the base of the plant at the drip zone. Do not apply directly at the stem. Cover the active root area. Foliar spray (curative). Dissolve 0.5–1 g per litre of water. Spray on all leaves, especially young leaves showing yellowing. Spray in early morning or evening. Repeat in 10–15 days if needed. What to expect: Chlorosis starts reversing within 7–14 days of soil application. Full green canopy recovery in 3–4 weeks. Severe deficiency may need two doses. When Not to Use Fe EDDHA 6% Avoid in these situations: Soil pH below 6: In acidic soils, iron is already highly available. EDTA-based chelates are more cost-effective at lower pH. Flooded paddy fields: Waterlogged conditions make iron hyper-available. Iron toxicity (bronzing) can occur. Do not apply in continuously flooded rice. Direct phosphate tank-mix: Do not mix Fe EDDHA directly with concentrated DAP or MAP solution in the same tank it reduces chelate stability. Apply separately or use drip intervals. Afternoon spraying in hot weather: Heat degrades the foliar solution before absorption. Always spray early morning or after sunset. Frequently Asked Questions What is the dose of Fe EDDHA 6% per acre for wheat? The recommended dose for wheat is 500–1,000 grams per acre, applied through fertigation or soil drench at the tillering to jointing stage. Dissolve in water and apply to the root zone for best results. Does Fe EDDHA 6% work in alkaline black soil? Yes. Fe EDDHA 6% is specifically designed for alkaline and calcareous soils with pH up to 9.5. It is the only iron chelate form that remains stable and plant-available in these soil conditions. Standard ferrous sulfate does not work reliably in black alkaline soils above pH 7.5. Why are my citrus leaves turning yellow even after applying iron fertilizer? If you applied ferrous sulfate or iron EDTA in alkaline soil, the iron likely precipitated and never reached the roots. Switch to Fe EDDHA for alkaline soils. Apply 20–50 grams per tree as a soil drench at the drip zone. New leaves should show recovery within 2–3 weeks. Can I mix Fe EDDHA 6% with other fertilizers in the drip system? Fe EDDHA can be mixed with most water-soluble NPK fertilizers and other micronutrients through fertigation. Avoid direct mixing with concentrated phosphate solutions (DAP, MAP). Always do a small jar compatibility test before tank mixing for the first time. Is Fe EDDHA 6% safe for drip irrigation systems? Yes. Fe EDDHA 6% is fully water-soluble and does not clog drip emitters. Drip fertigation is actually the preferred application method it delivers iron directly to the root zone with maximum efficiency and zero wastage. How is Fe EDDHA 6% different from ferrous sulfate? Ferrous sulfate contains higher iron percentage (19%) but the iron immediately reacts with soil calcium in alkaline soils and becomes unavailable. Fe EDDHA 6% keeps iron in a chelated, protected form that stays in soil solution and is directly absorbed by roots. In soils with pH above 7.5, Fe EDDHA gives reliable correction; ferrous sulfate does not. How many days to see results after applying Fe EDDHA? In most field and vegetable crops, yellowing (chlorosis) starts reversing within 7–14 days of soil application or fertigation. Full canopy recovery typically takes 3–4 weeks. For foliar application, visible improvement appears within 5–10 days, but the correction is less complete than soil application.
