Libfer SP is an iron fertilizer with EDDHA chelate. Thanks to the chelate, the iron is and remains stable and available, even in soils with a low pH value. This iron chelate is one of the few iron chelates that is effective in soils/substrates with a high and low pH. It contains a large part of the biologically effective isomer, the ortho-ortho isomer and has an ortho-ortho content of 4%. Because this microgranulate dissolves iron fertilizer quickly and completely, unlike other iron chelates where residue remains, it does not clog any residue that could block nozzles or other parts.
Iron is necessary for the production of chloroplasts and therefore has a very important function in the photosynthesis of a plant. The nutrient is also important for the development of growth points in the roots.
Application
Use Libfer SP for extra gift of iron. Because iron precipitates relatively quickly, the use of a chelate is recommended to prevent iron deficiency. This EDDHA iron chelate is well suited for use in soils/substrates with a low pH value, but also for soils/substrates with a high pH value.
If Libfer SP is administered by irrigation, rinsing with clean water is necessary.
Dosage

| Preventive |
1 to 3 grams per m2 |
| Moderate deficiency |
4 to 7 grams per m2 |
| Severe deficiency |
8 to 10 grams per m2 |
In the case of roses, Fe-EDDHA can make it more difficult to absorb manganese. Watch out for chlorosis and, if necessary, spray manganese sulphate or chelate.

The dosage mentioned above for crops on substrate applies to a 100x concentrated solution in A-tanks of 1000 litres.

Libfer SP should be applied in fruit cultivation through the roots in the period from mid-March to mid-June. The required amount should be given immediately before or during the rain. It is important to do the application in a moist soil/substrate.
Packaging
Libfer SP is available in 20 kg packs. The Libfer SP is also available in smaller packages of 1 kg and 5 kg, but under the name Easygro Fe-EDDHA 6% (4.0 o-o).
