MICROELEMENTS - IRON Iron: It possesses a very low mobility. It plays a very important role in the synthesis of chlorophyll and in the photosynthetic process. It activates numerous biochemical reactions and is absorbed as ion Fe++ or ion Fe+++. Series from the Gerbera Cultivation Manual that entails useful information for Gerbera Growers. Informative advice from one specialist to the other. Published by Schreurs and Written by Dottore Mercurio. In sub-alkaline and alkaline ground it can become unavailable due to it’s insolubility with Carbonates and Phosphates (in these cases, it is necessary to raise the doses normally recommended).
Deficiencies: The Gerbera is very sensitive to variations of Iron in it’s leaves, showing itself as interveinal chlorosis (yellowing) on the youngest leaves. In serious cases, initially there is a leaf de-coloration to creamy yellow, and the leaves become smaller.
Following this there occurs a necrosis of the leaf apexes and interveinal zones. In an advanced phase of the phenomenon the leaf veins also become yellow. A useful suggestion is to add the element during the base fertilization, before the transplant.
Excesses: It can cause deficiencies of Manganese. Click HERE to order the Gerbera Cutivation manual |
