Micronutrients are involved in all the metabolic processes of the plant (growth, budding, flowering, fructification…), and although they are required at low doses, a deficiency leads to reduced vigour and fructification of the crop.

Iron deficiency in the plant is generally not due to an actual absence in soil, since it is required in minute amounts. It is most often blocked for some reason and cannot be assimilated by the roots.

The usual cause of the blocking is an inadequate substrate pH (too high for the plant).

Kaliter® Excalibur is a high-quality iron chelate developed to prevent and correct iron chlorosis
in plants. As it is formulated with chelating agent EDDHA, it confers the best features to the product to solve iron deficiencies.

Kaliter® Excalibur provides the following advantages:

• It optimises photosynthesis efficiency and improves plant metabolism.
• As a result of the selection of the chelating agents, it provides stability and persistence in all types of soils.
• It improves the sanitary state of the crop, providing higher resistance to adverse situations.
