Fertiliser use in the Great Barrier Reef catchment

Pulsford, 1996:

"The report provides, for each catchment, a summary of major land uses and some details of fertiliser use practices. The area, mean annual runoff and rainfall data are tabulated for each catchment, as are historical usages of phosphorus and nitrogen. For 1990, tables are provided to show the total quantities of the nutrients applied to the main groupings of crops and pastures, the averages rates for the catchment and ratios of nutrient applications to mean annual runoff volume.

The more significant statistics contained in the report include:

  • The total area of the 28 catchments from the Daintree to the Mary River, is 38 million hectares.
  • Almost 83 000 tonnes of nitrogen were applied to crops and pastures and in stock feed supplements in 1990. This was about the same as had been applied, cumulatively, up to 1945."
