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.
Although Cropmaster 15 generally mixes well with other products, it is not compatible with the following:
Superphosphate, Sulphur Super 30 and Magnesium Oxide
Cropmaster 15 can be compatible with the following under certain circumstances:
Segregation may occur when mixed with product with differences of particle size.

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
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.
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.
