Diammonium phosphate (DAP) is the world's most commonly used nitrogen and phosphate fertiliser and is used where sulphur levels are good or where sulphur is applied separately. DAP is generally used on pastures and grain crops and is also used in blends for sugarcane and in horticulture.
Monoammonium phosphate (MAP) is a nitrogen and phosphorus fertiliser generally used where soil has a high phosphorous requirement and where sulphur levels are adequate or where sulphur is applied in a separate application. MAP is generally applied at the time of planting for cotton, grain and forage crops.
Triple Superphosphate (TSP) is manufactured by treating phosphate rock with phosphoric acid. TSP has a higher phosphorus content than that of SSP, however it contains very little sulphur. TSP is used in cropping and legume based pastures where little or no sulphur is required and is often used in blended NPK fertilisers.
Single Superphosphate (SSP) is manufactured by treating phosphate rock with sulphuric acid. SSP is particularly popular on legume crops and perennial pastures where both phosphorus and sulphur are required.
