To reduce the amount of nutrient applied following low rates of mill mud without negatively impacting growth
Mill mud contains a large number of nutrients, some of which are in quite high concentrations. It also has the capacity to act as a soil ameliorant and aid in soil structure. Following the application of large rates of mill mud it is common to decrease nutrients, particularly nitrogen and phosphorus.
There is little knowledge about how much fertiliser can be reduced after mill mud is applied at low rates. This trial will investigate different application rates of nutrients following low mill mud application to determine what is required for the following plant cane crop.
