YaraTera Rexolin® E13 5kg

YaraTera Rexolin® E13 is a stable, water-soluble Fe-EDTA chelated iron micronutrient containing 13.3% Iron (Fe). It is suitable for agricultural and horticultural crop nutrition through fertigation, hydroponic systems, soil application and foliar feeding. Rexolin E13 is fully chelated with a chelate stability range of pH 1.5–6.5.

What is YaraTera Rexolin® E13?

YaraTera Rexolin® E13 is a stable, water-soluble iron chelate in which iron is chelated by EDTA. It is designed to provide iron as part of agricultural and horticultural crop nutrition programmes.

Iron is an essential micronutrient involved in photosynthetic activity. Under certain soil, water and growing conditions, iron availability can become limited even when total iron is present, making the correct form of chelated iron important in crop nutrition.

Why Use Fe-EDTA Chelated Iron?

Iron can react with other components in soil or nutrient solutions and become less available to plants. Chelation helps keep iron soluble and available within the effective stability range of the chelate.

What Does Iron Do for Plants?

Iron plays an important role in photosynthetic activity and healthy crop development. A crop can also experience mild micronutrient deficiency before clear visual symptoms become visible. This subclinical deficiency is sometimes referred to as “hidden hunger”.

Correct diagnosis should consider crop condition, soil or substrate, irrigation water, pH and the overall fertiliser programme before micronutrient application.

Suitable for Multiple Applications

YaraTera Rexolin E13 can be used across different agricultural and horticultural crop nutrition systems.

Actual application rate should be determined according to crop requirement, growing system, soil or substrate condition, irrigation water quality and the overall nutrient management programme.

Rexolin E13 Chelate Stability

Different iron chelates are stable across different pH ranges. Rexolin® E13 contains Fe-EDTA, with chelate stability approximately between pH 1.5 and 6.5.

This range refers to the stability of the Fe-EDTA complex and should not be interpreted as the recommended operating pH for every crop or fertigation solution. For higher-pH or highly calcareous conditions, another type of iron chelate may be more appropriate.

How to Choose the Right Iron Chelate

Iron chelates such as EDTA, DTPA, EDDHA and HBED have different pH stability ranges. Product selection should therefore take into account soil, substrate and irrigation water pH. Rexolin E13 is an Fe-EDTA product and is generally suited to acidic to near-neutral conditions within its chelate stability range.

Storage

Keep the product in its original packaging and store in a dry place at ambient temperature below 25°C. Protect from direct sunlight and moisture.
