• Apply in the early morning or late afternoon to improve foliar absorption and avoid scalding.

• In calcareous soils or soils with a high pH, ​​EDDHA chelates are preferable, as they are the only ones stable above pH 7.5–8.

• Maintain constant soil moisture after applying iron: drought severely limits its availability.

• Do not mix in the same tank with highly alkaline products or calcium to avoid precipitation.

• Repeat application every 2–4 weeks depending on the severity of chlorosis and the type of crop.

• In sensitive ornamental plants (hydrangeas, gardenias, citrus), it may be necessary to apply several times a year.

• Perform a preliminary test if using for the first time or on young plants.
