Cropmaster 13 is a blend of DAP with chipped Potassium Chloride. These components all have similar particle size (2-4mm diameter) which minimises segregation during transport and spreading.
The colour of the individual components can vary depending on where they are sourced. DAP can vary from light brown to black and Potassium Chloride can be red to pink or white to grey. Please note that colour does not indicate the chemical quality of the product.
Although Cropmaster 13 generally mixes well with other products, it is not compatible with the following:
Superphosphate, Sulphur Super 30 and Magnesium Oxide
Cropmaster 13 can be compatible with the following under certain circumstances:
Segregation may occur when mixed with product with differences of particle size.

Provide nitrogen (12.6%), phosphate (14%) & potassium (15%) for field crops, greenfeed brassicas, sheep, beef and dairy pasture
A cost effective product providing readily available nitrogen, phosphate and potassium
Has good spreading and flow characteristics
The primary use for Cropmaster 13 is as a fertiliser to provide nitrogen (12.6%), phosphate (14%) & potassium (15%) 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.
Use as a planting fertiliser for field crops at 60-200kg/ha. Although at the higher rates it may be advisable to broadcast rather than drill the product. For process crops, rates can be much higher with an application rate of 150-625kg/ha depending on P requirements. For greenfeed brassicas, an application rate of 100-300kg/ha is required. It is important to avoid seed contact. If direct drilling, use lower drilling rates (<100 kg DAP/ha). If more is required, the balance should be broadcast.
