Olega Fer 3% N + 3% Fe Foliar Fertiliser 5lt

1. What it is & how it works

Q1. What is DCM Olega® FER and what does it do?

DCM Olega® FER is a liquid foliar fertiliser containing 3% iron, 3% urea nitrogen, and 3% seaweed extract, designed specifically to prevent and correct iron deficiency — delivering a
faster and more intense greening response than broad spectrum foliar products or soil-applied iron treatments.

Q2. Why does DCM Olega® FER use two forms of iron, and how do they work together?

DCM Olega® FER combines 2% citrate-complexed iron with 1% DTPA-chelated iron — the citrate complex releases iron rapidly on the leaf surface for an immediate greening response, while the DTPA chelate maintains a more stable pool of available iron for sustained uptake and translocation through the plant.

Q3. What causes iron deficiency, and why is foliar application often more effective than treating the soil?

Iron deficiency is usually caused not by a lack of iron in the soil but by conditions that prevent root uptake — high pH, waterlogging, compaction, or cold — making foliar application
the most reliable corrective route because it bypasses the root and soil chemistry entirely.

2. Application, timing & restrictions

Q4. When and how should DCM Olega® FER be applied?

Apply during the active growing season (spring to summer) once plants are well in leaf, preferably in the late afternoon or evening on slightly moist plants — never in blazing sun or above 25°C, never on opened flowers, and always start at the lowest recommended dose on the first application.

Q5. What are the recommended rates for DCM Olega® FER?

Field rates range from 1–10 L/ha depending on crop and whether the application is preventive or curative, always diluted with a minimum of 400 litres of water per hectare — with a high-rate fast greening option for lawns at 40–60 L/ha in 1,000 litres
of water per hectare.

3. Practical & commercial

Q6. How does DCM Olega® FER differ from DCM Olega® Complex, and when would I choose each?

DCM Olega® Complex is a broad-spectrum foliar product addressing general NPK and multi-micronutrient needs; DCM Olega® FER is an iron specialist for situations where iron
deficiency is the identified or anticipated problem — use FER when chlorosis of young leaves is present or when growing conditions are known to restrict iron availability.

Q7. How is DCM Olega® FER packaged and stored?

Available in 5-litre drums (four per case, 20 litres total) and 15-litre drums — store in a frost-free place and shake well before each use.
