Although Ammonium Sulphate generally mixes well with other products, it is not compatible with the following:
Ammonium Sulphate can be compatible with the following under certain circumstances:
Superphosphate, Sulphur Super 30 and Dry Lime.
Segregation may occur when mixed with product with differences of particle size.
Flexi-N (magnesium coated Urea) can be used as a substitute when mixing with Superphosphate based products
Refer Compatibility chart.
Provides an equal balance of readily available nitrogen and sulphur.
Meets short term sulphur deficits in cropping and patoral situations.
The safest nitrogen fertiliser to mix with non-superphosphate based fertilisers.
Volatilisation of ammonia is very low compared to Urea - the timing of application is flexible.
Ammonium Sulphate will meet short term sulphur deficits of crops and pastures, crop quality requirements, or the maintenance sulphur requirements of pasture.
Ammonium Sulphate Granular is reccommended for arable and cropping situations, silo fills and drrilling seed. It is used in Cropmaster, Ammo 31 and Ammo 36 blends.
Ammonium Sulphate Standard is recommended for pastoral blends and broadcasting.
Actual spreading rates will vary according to farm type, climate, productivity and soil 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.
Volatilisation of ammonia from Ammonium Sulphate is very low compared to Urea, therefore the timing of the applications is flexible.
Clean equipment after use to avoid corrosion. As with most solid fertilisers, Ammonium Sulphate can be stored over a season as long as it is kept in a cool, dry, well ventilated area.
