Sulphate of potash (also known as SOP) is widely used in the horticultural sector as well as organic's to provide potassium for chloride-sensitive crops.

It is largely inert and may be blended with virtually all other fertiliser products. 
 

Sulphate of Potash (SOP) is a concentrated source of potassium and sulphur which dissolves readily after application to soils and can be easily blended with a wide range of other fertilisers.

SOP helps promote fruit and vegetable sweetness, flavour and colour.

Benefits
• Suitable for use in a variety of horticultural settings.
• A concentrated source of potassium which dissolves readily after application to soil.
• Even-sized granules for ease of handling and spreading.
• Chloride free.

Directions for use
Sulphate of Potash is mainly used in horticulture.
Apply to crop or soil in small, frequent applications to maximise plant uptake and minimise leaching in soils vulnerable to loss.
Avoid contact with seed.

Storage information
To maintain product quality, SOP should be stored in cool, dry conditions and should not be stored for a prolonged period.

Keep out of reach from children and pets.

WARNING - Avoid placement near waterways.
For detailed advice on good fertiliser spreading practice, see the guidelines in the Code of Practice for Nutrient Management, which can be downloaded from fertiliser.org.nz.
