Iron plays a crucial role in photosynthesis in plants since it is required for the formation of chloroplasts. The nutrient is also necessary for the roots' growth points to form. An iron fertilizer containing EDDHA chelate is called Libfer® SP Iron Chelate. Even in low-pH soils, the iron is stable and readily available because of the chelate. One of the few iron chelates that works well in both high and low pH soils and substrates is this one.

It has a 4% ortho-ortho content and is largely composed of the ortho-ortho isomer, which is the biologically active isomer. This microgranulate does not clog any residue that could block nozzles or other parts because it dissolves iron fertilizer rapidly and completely, in contrast to other iron chelates where residue is left behind.

Fruit cultivation should apply Libfer SP iron chelate through the roots between mid-March and mid-June. Give the required amount as soon as possible before or during the rain. It is crucial to apply the material in a damp substrate or soil.
