| Physical description |
Physical Description Magnesium Oxide is an off-white coarse chip (2-5mm) with some fine powder. |
| Farm types |
Cropping, Dairy, Livestock, Horticulture, Lifestyle
|
| Uses include |
Capital fertiliser, Magnesium source, Maintenance fertiliser, Pasture growth
|
| Cautions for mixing |
Conditions For Mixing Although Magnesium Oxide does mix well with some products, it is not compatible with the following: Sulphur Super 30, Urea, Flexi-N (magnesium coated Urea), Ammonium sulphate granular, Ammonium sulphate standard, Calcium Ammonium Nitrate (CAN), Nitrophoska, Cropmaster DAP, Mono Ammonium Phosphate (MAP), Ammonium Nitrate, Potassium Nitrate. Segregation may occur when mixed with product with differences of particle size. Refer Compatibility chart. When mixed with other fertilisers, it is important to reduce the bout width when spreading, as Magnesium Oxide does not spread as well as many other products |

Suitable for pastoral, arable and horticultural applications
Cost-effective source of magnesium where large amounts are required
Maintain or increase soil pasture magnesium levels, both for plant and animal requirements
Magnesium Oxide is a cost-effective source of magnesium where large amounts are required.
Availability of the magnesium from this product will rely on soil acidity because Magnesium Oxide slowly dissolves through reactions with hydrogen (acid) ions in the soil. The rate of dissolution will depend on particle size, the finer the particle, the faster it will dissolve. The Magnesium content will become plant available within 6 months of application in most conditions.
Uses
This high analysis fertiliser is suitable for pastoral, arable and horticultural applications.
Magnesium Oxide is used to maintain or increase soil magnesium levels and pasture magnesium levels, both for plant and animal magnesium requirements. Its use can reduce the need and amount of direct animal Magnesium supplementation as well as reducing animal losses from hypomagnesaemia. However it may not always supply enough magnesium for animal requirements in the spring,so supplementation should be considered.
Application rates and advice
Rates of application are typically up to 40kg/ha (21 kg Mg/ha) as a maintenance dressing, or up to 200kg/ha as capital inputs.
Actual spreading rates will vary according to farm type, climate, productivity, soil type and crop type. Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate. Call our Customer Centre for information.
When mixed with other fertilisers, it is important to reduce the bout width when spreading, as Magnesium Oxide does not spread as well as many other products.
As with most solid fertilisers, Magnesium Oxide can be stored over a season as long as it is kept in a cool, dry, well ventilated area. It can be very dusty so precautions may need to be taken.
