A fully soluble fertiliser that provides Nitrogen and Magnesium nutrition for vegetables, fruits, vines, flowers, turf and ornamentals.
The Nitrogen in Campbells Nitro-Mag is fully available to plants and provides an immediate and predictable growth response. Nitro-Mag is a fully soluble and available fertiliser and allows Magnesium and Nitrogen nutrition to be applied via fertigation and/ or foliar application.
At the centre of every chlorophyll molecule there is a Magnesium atom. Chlorophyll gives plants there green colour and allows plants to properly photosynthesize. A lack of Magnesium can reduce the green pigmentation in plants and reduce photosynthesis.
Campbells Nitro-Mag cannot be lost to the atmosphere like Urea or Ammonium based fertilisers and:
- Is not affected by temperature, so nutrients are still available when conditions are cold & wet
- Does not contain harmful chlorides or heavy metals
- Is not acidifying to the soil
Where Magnesium requirements are high and supply is lacking, Nitro-Mag can be a significant part of the total Nitrogen budgeting for the fertiliser program. However, the quick acting form of Nitro-Mag means that the product can be specifically applied in response to plant or visual analysis to correct or prevent a deficiency of Magnesium and/ or Nitrogen occurring.
Campbells Nitro-Mag greenhouse grade can be applied through the fertigation system or used in hydroponic systems. Nitro-Mag is particularly suitable in high value vegetable crops where colour and visual appearance is important for the end product.
Caution: Avoid any foliar application during extremes of climate and during flowering
General rates for horticultural crops are between 25 to 50 kg/ha through the fertigation system. When applying Campbells Nitro-Mag through the irrigation system more frequent and smaller applications guarantee the nutrients are supplied to the plants without being lost due leaching or excessive rainfall. The actual rates, number of applications and their timing will vary considerably for different crops and for different districts. Before application, seek advice from your Campbells distributor or your local agronomist.
