QUELMAG

4% w/w Water-soluble Calcium Oxide (CaO).

4% w/w Calcium Oxide (CaO), chelated with EDTA.

QUELMAG is a liquid magnesium (Mg) chelate designed to prevent and correct magnesium deficiencies in all types of crops.

Magnesium is an essential element for plant photosynthesis as it forms part of the chlorophyll molecule; it also promotes the transport and accumulation of sugars in storage organs.

Thanks to its 100% chelated formulation, QUELMAG is the most effective and rapid way to correct magnesium deficiencies in cultivated plants.

Apply as a foliar spray at a rate of 150–300 cm³/hL.

Depending on the severity of the deficiency, 2 to 3 spray applications are recommended, spaced 20 days apart.

Direct application to the soil: this can be done by spraying the soil directly, followed by watering to help the product reach the roots more easily.

The recommended application rates for citrus and fruit trees are:

Small trees and nursery plants: 1–7.5 cm³ per plant.

Young trees: 7.5–25 cm³ per plant.

Mature trees: 25–50 cm³ per plant.

Application by fertigation: Applied together with irrigation water at a rate of 2.5–5 L/ha.

Depending on the severity of the deficiency, 3–6 treatments spread throughout the growing season will be required.

For foliar applications, it can be mixed with all commonly used fertilisers and plant protection products; however, it must not be mixed with products that are strongly alkaline or with fertilisers containing high concentrations of phosphorus.

It is advisable to avoid the hottest part of the day and to water the foliage thoroughly.
