This EDDHA iron chelate is used in all kinds of crops. Even in ornamentals, where the aesthetics of the plant is a vital factor for its correct commercialization.

Application dose of chelated iron

The application doses of the EDDHA iron chelate vary depending on the phenological state of the plant, its age of cultivation in the case of vineyards and orchards, the time of year, as well as the physical and chemical properties of the soil, and method of cultivation. app.

Note that there are certified EDDHA iron chelates on the market that are compatible with integrated management and organic production programs. An example of an ecological EDDHA iron chelate is JISAQUEL ® Fe S-6, manufactured by the plant nutrition specialist firm JISA.

But to be able to give some data as a reference on the possible application doses of the EDDHA iron chelate in crops, the following doses are valid, for example.

Application dose of iron chelate in fruit growing:

  • Citrus, between 7 and 30 grams per foot.
  • Young stone fruit trees such as apricot trees, plum trees, peach trees, etc. between 5 to 20 grams per foot.

Application dose of iron chelate in horticultural and ornamental plants:

  • 0.5 grams per square meter in a young culture stage.
  • From 0.5 to 5 grams at the start of production.
  • From 5 to 7 grams per square meter when they are in full production.
  • In young red fruit plants (strawberry, raspberry, etc.). About 0.5 grams per square meter.
  • In red fruit plants at the beginning of production. About 0.5 to 0.7 grams per square meter.
  • In red fruit plants in full production. About 0.7 to 1.5 grams per square meter.

Finally, add that, although with all possible reservations, the specific iron chlorosis correctors are usually compatible with most products and phytosanitary products, except those that are strongly alkaline or that contain metallic micronutrients, such as copper or manganese.
