| Physical description |
Physical Description Cropmaster 15 is a blend of DAP, chipped Potassium Chloride and Ammonium Sulphate Granular. These components all have similar particle size (2-4mm diameter) which minimises segregation during transport and spreading.
The colour of Cropmaster 15 can vary, depending on the source of the components. DAP varies from light brown to black, Ammonium Sulphate Granular varies from reddish brown to white while Potassium Chloride varies from red-pink or white to grey.

Provide nitrogen (15.1%), phosphate (10%), potassium (10%) & sulphate (7.7%) for field crops, greenfeed brassicas, sheep, beef and dairy pasture
A cost effective product providing readily available nitrogen, phosphate, potassium and sulphate
Commonly used in cropping situations where potassium is required
Cropmaster 15 is cost effective, providing readily available nitrogen, phosphate & potassium with good spreading and flow characteristics.
Cropmaster products are blends - they are made up of separate granules of each different nutrient. Cropmaster 15 is a blend of DAP granules & chipped Potassium Chloride. In compound fertilisers like the Nitrophoska Products range each granule contains all the different nutrients. For this reason blended fertilisers are usually a lot cheaper than compound products.
As long as the granules in the blend are of a similar size (as they are in the Cropmaster range) the is usually little difference in the performance of a compound compared to a blend. However, in some intensive production situations (e.g horticulture) small differences can be important and it may more beneficial to use a compound.
Uses
The primary use for Cropmaster 15 is as a fertiliser to provide nitrogen (15.1%), phosphate (10%), potassium (10%) & sulphate (7.7%) for field crops, greenfeed brassicas, sheep, beef and dairy pasture. It can be used as an alternative source of phosphate if soil sulphate levels are high or sulphate is not required.
Application rates and advice
Because all Cropmaster products contain nitrogen, correct calibration of application equipment is important.
As with most solid fertilisers, Cropmaster 15 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.
Also, clean drills and spreaders after use to avoid corrosion.
Spring planting for cereals & legumes 180-375kg/ha. Where more than 200 kg is required, broadcast the balance. If direct drilling, lower these rates to less than 125kg Cropmaster 15/ha for cereals. In some crops e.g. potatoes, rates of up to 1500kg/ha can be used, usually via a planter. At very y high rates it is preferable to broadcast some of the fertiliser, and apply the balance at planting or as a side dressing.
Pastoral
For boosting pasture growth, apply 125-250kg/ha. For hay/silage situations, use Cropmaster 15 at 180-375kg/ha to allow for the heavier removal of nutrients by these crops.
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.
