Liquid iron plant nutrient.

Ferrogat – properties
Ferrogat is a solution containing 0.65% chelated iron.

Ferrogat – Chemical composition
30% Fe-EDTA

Fertigating with Ferrogat
When fertilizing with Ferrogat via the irrigation system, it is advisable to inject it towards the end of the irrigation application, specifically during the last third of the irrigation turn, so that it remains in the bulk area of the active roots. The ability of the crop to absorb iron depends on the presence of a high concentration of available iron in the vicinity of its roots. Therefore it is recommended to apply the recommended amount of Ferrogat in a short period of time and at high concentration, rather than applying it in diluted form during the entire irrigation.

It is also recommended to split the yearly recommended amount of Ferrogat into a limited number of fairly large doses. For example, if an annual dose of 100 Lt/ha is required, it is preferable to apply 4 doses of 25 Lt/ha, rather than 10 doses of 1 litre each.

It is more efficient and convenient to continuously provide iron with Ferrogat, rather than wait for iron deficiency symptoms to develop. Preventive fertilization avoids damage to the plants and the reduction of yields.

Recommendations for the application of Ferrogat

Prior to or with planting/ sowing – 20-30 litres/hectare.
Two to three additional doses of 30 – 40 litres/hectare during the growing season.
60 – 80 litres/hectare upon initiation of flowering.
If deficiency symptoms develop earlier, increase the dosage by 30 – 40 litres/hectare.
Two to three applications of 20 – 30 litres/ hectare each, starting with the initiation of irrigation.
Total 40 – 80 litres/hectare.
Weekly application of 20 – 30 litres/hectare. Tomatoes
Every second week, 40 – 60 litres/hectare. Cucumbers
According to crop type, 20 – 60 litres/hectare weekly or every second week. Flowers

Artificial or detached growing media

According to crop type, maintain a constant concentration of 1 – 1.5 ppm iron in the irrigation water; 0.16 – 0.25 litres Ferrogat /m³ of irrigation water, or as weekly applications.


Quantity Lt/ha Quantity Lt/tree No. of doses Deficiency level
40 0.10 1 Light chlorosis
60 0.15 2 Moderate chlorosis
80 0.20 3 Severe chlorosis
100 0.25 4 Chlorotic tree

Calculated for 400 tree/hectare

Advantages of Ferrogat
Ferrogat is a mixture of two iron chelates:

70% of the iron is in the form of Fe-EDDHMA, one of the most stable iron chelates available. This chelate remains stable over a very wide range of pH values (including above pH = 10), and remains available in soils with a high content of line (CaCO3) for a long periods of time.

The remaining 30% of iron is in the form of Fe-EDTA, which is relatively unstable at pH values above 7 and remains available to the plant for approximately one week.

Ferrogat is a ready-to-use liquid preparation, requiring no further handling. The iron in Ferrogat is completely and immediately available to the plant.

Ferrogat is supplied in 10 litres cans, jumbo containers of up to 1,000 litres, in bulk or added to a liquid fertilizer containing macro- elements (N,P,K).
