5L Liquid Fertiliser Magnesium Chelate
This 5 L product is a liquid magnesium feed (5% MgO). Magnesium is the central element of the chlorophyll pigment, so it can be used to green up turf where iron levels are already sufficient or where grass is showing signs of magnesium deficiency.
Key Features
- Supplies magnesium, the central element of chlorophyll, for green-up
- 5% magnesium oxide (3.02% elemental) plus 2.20% nitrate nitrogen
- Chelated formulation – the nutrient is protected from precipitation for more efficient uptake
- A 5 L pack covers 10,000 m²
How to Use
| Applicator | Application Rate | Water Volume | Pack Size (Litres) | Pack Coverage (m²) |
|---|---|---|---|---|
| Boom Sprayer | 5 ltr/ha | 200 ltr/ha | 5 | 10,000 |
| Knapsack | 0.5 ml/m² | 20 ml/m² | 5 | 10,000 |
- Half fill the sprayer with clean water, add the concentrate as required, then keep mixing thoroughly while topping up with the remaining water.
- Use a suitably calibrated sprayer and apply evenly, taking care not to overlap or miss areas.
- Irrigate the treated area thoroughly if no rain falls within 2 days of application.
- Do not apply during hot, dry weather or in frosty conditions.
Applications
- Green-up where there is already ample iron
- Acidic soils where grass shows signs of magnesium deficiency
- Situations where magnesium demand has risen, for example after potassium levels have been raised or a pH amendment has been applied
What is a Chelate?
The word chelate (pronounced 'key-late') comes from the Greek χηλή (chele), meaning claw, because the chelating molecule wraps around the central molecule much like a lobster's claws. In practice, a chelating agent is an organic molecule that encapsulates a plant nutrient molecule and stops it from precipitating out, which would otherwise make the nutrient unavailable. The change in surface properties of the chelated molecule makes the encapsulated ions far more likely to be absorbed through the roots and leaf tissue, so the applied nutrient is used more efficiently.
