Chelated Micronutrients (Foliar Application)

About

What Are Chelated Micronutrients - and Why They Matter in Modern Agriculture Even after applying regular micronutrients, do your crops still show yellowing leaves, poor fruit set, or stunted growth? That's because essential elements like iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) often get locked in the soil and become unavailable to plants. Chelated micronutrients solve this problem. In these fertilizers, each metal ion is bound to a special organic molecule called a chelate - forming a ring-like "claw" structure that protects the nutrient and keeps it soluble. This ensures the micronutrient remains readily available for plant uptake even in challenging soil conditions. At Ases Chemical Works , our Chelated Micronutrient Range is formulated specifically for foliar application , helping farmers achieve quicker correction of deficiencies and better yields. How Chelation Works The term chelate comes from the Greek word chēlē , meaning claw - because the chelating molecule grips the nutrient ion tightly, shielding it from reactions that would otherwise make it unavailable. For example, in alkaline or calcareous soils, micronutrients can react with hydroxide (OH⁻) or carbonate (CO₃²⁻) ions and precipitate. Chelation prevents this, keeping the nutrient in a plant-available form. Common chelating agents include EDTA , DTPA , and EDDHA , each designed to maintain stability under different soil pH levels. Benefits of Using Chelated Micronutrients · Improved nutrient uptake - Chelated forms are easily absorbed through leaves and roots. · Effective in high-pH or calcareous soils - Chelates stay available where normal micronutrients fail. · Faster deficiency correction - Foliar sprays deliver nutrients directly to plant tissues. · Reduced nutrient loss - Chelates minimize fixation or precipitation losses. · Better crop performance - Promotes greener foliage, stronger roots, and higher yields. · Cost-effective - Higher efficiency means you need smaller doses compared
