Test for Iron (Fe)

Iron (Fe) is an important component of plant nutrition. In case the plants have fading leaves this may be due to lacking iron.

The sera Fe-Test provides quick information about possible deficiencies.
Detection of chelatized (stabilized) iron is possible.

Sufficient for approx. 75 measurements.

Iron is one of the many important nutrients for all aquatic plants. Inadequate iron level affects plants adversely. However, high iron content in the water harms the fish.

Not every type of iron is usable by the plants. Thus, iron from tap water is disadvantageous.

Discolored yellow leaves of aquatic plants are a definite symptom of iron deficiency.

Iron values of above 0.5 mg/l are harmful for fish and plants.

The ideal iron concentration immediately after fertilization is 0.25 – 0.5 mg/l.
