Ciro Iron Chelate 

Iron chelates

Iron is essential for the formation of chlorophyll. Approximately 80% of the amount of iron in the plant is located in the chloroplasts. Further, the element is a constituent of a large number of proteins and enzymes. Iron deficiency is usually to poor availability in the soil or inhibited transport in the plant. A high pH, poor root growth or too low a bottom temperature of iron can strongly inhibit the incorporation of, despite the fact that iron is generally more than sufficient in the soil. Lack of iron, it is first visible in the head of the plant. The leaves turn yellow and in severe cases even white. This is because after fixation in the plant no more redistribution can take place of iron.
New leaves should therefore be constantly updated with new iron from the roots. Iron is only absorbed through the root tips and therefore the plant should always form new roots to continue to meet the iron requirements. As the leaves grow older the yellowing can be reduced or disappear altogether. The condition is that the plants get enough iron administered.
The magazine incidentally remains weaker.

WHY iron chelate?

Plants respond to iron deficiency with mechanisms to enable sufficient iron take it anyway. The roots H + ions, for example, excrete in order to mobilize the iron around the roots. Calcareous soil contains a lot of HCO3- ions. These ions neutralize the H + ions which iron deficiency in calcareous soils is difficult lifted. In addition, growing roots themselves chelate-like agents that secrete iron can get out of the ground in solution.
Chelates are organic substances which ensure that, for example, iron is readily available to the plant.
Unfortunately, these chelates are, of course, are often not sufficiently present in the medium. In addition, they are not very stable. In order to overcome this, there have been developed a variety of iron chelates that are more stable.

VARIOUS TYPES chelates

The stability of the iron chelates is dependent on the pH and the concentration of the other nutrients. The choice of the proper type of iron chelate forms the basis for effective iron fertilization. Below is an overview of the most common iron chelates and their main characteristics.

EDTA: This is an iron chelate that works up to a pH of 6. In this type of recycling iron will easily detach from the chelate and precipitate in the system.
In the Netherlands this type is mainly used by the compost industry, in sheet feeders and in a number of compound fertilizers.

DTPA: The most commonly used iron chelate in the current greenhouses. This chelate can be used to pH 7. Even in this type of recirculation can be used without problems.
Ciro Products provides two liquid DTPA chelates namely 3 and 6%.

The version is 3% on the basis of Sodium and 6% on the basis of ammonium.
6% is the highest quality DTPA that get and completely free of sodium and sulfate and thus very suitable for recirculation.

EDDHA: Can be used to pH 10. Even in recirculation systems EDDHA Iron can be used fine.

Use in Fertilizer tank ( A )

When dosing of (Iron) chelates is also the pH of the fertilizer solution is important.

If the pH is too high or too low, the iron can chelate from the "fall" of the chelate can be broken. If your FERTILIZER TANK with DTPA iron starts to foam or the liquid is virtually clear then it is likely that the pH of the tank is not good. Chelates can also be decomposed by light.
