Product Description  

DOWCROP®️EDDHA, is a chelate that protects nutrients against precipitation in a wide pH-range: 4-9, which is higher than EDTA and DTPA in pH range. This makes the EDDHA-chelates suitable for alkaline and calcareous soils as well as soils containing high levels of carbonate. It is mainly used for fertigation in open fields and soil injection as well as fertigation in high tech, soil-less cultures. The product contains the highest percentage of the ortho-ortho is omere: 4.8% o-o and it is easy, rapid to dissolve in water and compatible with most water-soluble fertilizers.

  • Iron chelates are the only effective way of correcting iron deficiency in alkaline soils because they are the only iron compounds stable enough to remain in solution in these conditions.

  • Chelates are complex organic molecules that are capable of binding to iron so tightly that

chemical reactions are prevented. As a result, a supply of soluble, biologically available iron is maintained.

The most suitable of these iron chelates for soil application is EDDHA FE 6% - a well-known iron source to all growers. Unfortunately, not all products described as Fe 6% EDDHA are as effective as they are claimed to be.

One reason for this is the very complex nature of the chelate, which consists of a number of parts called isomers.

Although all of the EDDHA isomers will chelate iron, one is biologically much more efficient than the others: the ortho-ortho isomer.

  •  EDDHA Fe 6% had a high proportion of this isomer providing the rapid response necessary for effective treatment of iron deficiencies.

  • In addition to the complex chemical structure a major factor in the quality of iron chelates is solubility, essential to ensure maximum availability to the plant.

Application Recommendation  

 EDDHA-Fe 6 works best when crops are not under moisture stress  and  are  supplied  with adequate major nutrients.

EDDHA-Fe 6 is most effective when applied at crop stages where demand for iron is most critical and when the crop is most responsive to iron applications.

If this product is to be applied as a liquid either on the soil or on the foliage, it is NOT necessary to pre-mix with a small amount of water. Instead, add this product directly into the solution tank slowly and maintain good agitation. Agitation and stirring should continue until the product is fully dissolved.

As a matter of precaution, for tank-mix applications with other agricultural inputs such as fertilizers and pesticides, it is advisable to prepare a sample mixture of these products to ensure good compatibility before the application.


Product Usage  



g/1,000 l water

Iron(Fe) content


M mol/L














EEDHA Fe 6 can be applied around the plants as a powder, liquid spray, and liquid injection or through drip irrigation systems

When applied as a powder, it should be washed in or irrigated with water within 4 hours of application.

When applied as a spray onto the soil, make sure that coarse spray nozzles are used and that adequate volume of water is used to wet the soil thoroughly.

When applied as a soil injection, it should be done at less than 1 meter apart.

General Rates of Application

The rates recommended below represent the upper and lower limits of the range. Actual rate to be applied depends on size of the plant and the level of need as determined by the level of deficiency of iron.


Application Rates

Apples and stone fruits

28g-140g per tree

Citrus, Avocados, Mangoes

Young tree 500g-700g per 100m2 Mature Tree:200-500g per tree

Annual maintenance: 100g-150g per tree


3.7g-7.5g per meter of row in a band or as a side dressing

Tomatoes, Cotton, Legumes, vegetables and root crops

1kg—2kg per hectare as maintenance or 2kg—5kg per hectare if chlorotic.

Apply prior to planting or when deficiency symptoms appear.

Ornamental Shrubs

20g-50g per bush


Applications: (10 - 50 kg/ha)

1x: In spring period

1x: At first symptoms of deficiency

The pH in the tank should be above 3.

The mentioned indicated dosages and application stage are subject to soil and climatic conditions, influence of previous crops and other specific conditions. Exact dosages and application stages can only be given after an objective diagnostic procedure by e.g. soil, substrate and / or plant analyses.


Applications on tree crops

This product is to be applied in a wide circular band under the full canopy of the tree, regardless of the method of application.

Note: Above application recommendations are under general conditions, your consultation to local agronomists are strong recommended.
