Product Description

Cropmaster Brassica fertilisers are a blend of Cropmaster DAP and Potassium Chloride, plus boron. These components all have similar particle size (2-4mm diameter) which minimises segregation during transport and spreading.

DAP can vary from light brown to black while Potassium Chloride can be red-pink or white to grey.

Why Use Cropmaster Brassica + Boron

  • Provide N (13.9%), P (15.4%) & K (9.5%) + B for forage brassicas
  • N& P are the two most essential elements for brassica production
  • Boron is added to prevent disease in boron deficient crops

Caution When Mixing

​Although Cropmaster Brassica + Boron generally mixes well with other products, it is not compatible with the following:

Superphosphate, Sulphur Super 30 and Magnesium Oxide

Cropmaster Brassica + Boron  can be compatible with the following under certain circumstances:

Dry Lime

Segregation may occur when mixed with product with differences of particle size.

Refer Compatibility Chart.

Important Information


    Provide nitrogen (13.9%), phosphate (15.4%) & potassium (9.5%) + boron for forage brassicas

    Nitrogen and phosphate are the two most essential elements for brassica production

    Boron is added to prevent disease in boron deficient crops

    The two most essential elements for brassica production are nitrogen and phosphate.  Cropmaster Brassica + Boron provides these necessary elements, with the addition of potassium for environments where soil potash levels are low to moderate.
    Boron is typically added for swede and turnip crops to ensure the bulbs do not suffer from Brown Heart, which is caused by a boron deficiency.
  • USES

    Cropmaster Brassica + Boron is designed for the establishment of forage brassica crops. They provide a balanced mix of nitrogen, phosphorus and potassium with the option of including boron (as Borate 46).


    Typical rates of application will be 250-300kg/ha, however it this will vary according to soil fertility and paddock history. If boron is included in the mix, ensure all the fertiliser is broadcast, and none goes down the spout with seed when drilling, due to the risk of germination injury.

    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.
    As with most solid fertilisers, Cropmaster Brassica + Boron can be stored over a season as long as it is kept in a cool, dry, well ventilated area. Store bags in a dry place ensuring they are tightly sealed.

    Always clean drills and spreaders after use to avoid corrosion.​
