OPTIFER

EC FERTILIZER – MICROELEMENTS MIXTURE IRON (Fe) + MANGANESE (Mn)

OPTIFER is a compound made of EDDHA iron chelate and EDTA manganese chelate especially indicated to cure multiple deficiencies of iron and manganese, frequent in fruiting plants and vegetables. Iron is a very important element in fact iron deficiency leads to a poor increasing of plants and a poor quality and production. OPTIFER is a high solubility product with a high stability of chelate fraction. Thanks to its formulation (IRON + MANGANESE) OPTIFER is a unique product which can be applied to many kinds of crops and soils.

OPTIFER must be applied on roots at the first evident multiple symptoms of iron and manganese deficiency. The product must be dissolved in the water at the indicated dosage, using almost 15 litres of water for each plant. It is recommended the supply by fertirrigation, lister or injectors. For better results, dissolve a part of the product in spring and another one in autumn (from August to October). In very dry soils we suggest to use a bigger quantity of water.

In general, OPTIFER must be used on adult plants at a dose of 18-30 Kg pro Hectar, according to crop needs. On young plants reduce the dose of 50%.

WARNINGS:
It is recommended to not expose to light, the EDDHA chelate agent is sensitive to light.
