Mallee Calculator

The Mallee Calculator is a simple spreadsheet model tailored to Mallee conditions. It was devised to help farmers in their estimates of potential yield and nitrogen fertiliser requirements of cereals and canola. It has been developed by CSIRO Land and Water, Adelaide.

The Mallee Calculator can be used in two decision making modes:

1. To determine a single application of nitrogen fertiliser at sowing. This is the simplest strategy, but involves the full risk of uncertain seasonal conditions.
2. To determine a split application of nitrogen fertiliser. The model allows for a revision of nitrogen fertilisation decisions in August-September which takes into consideration the actual amount of rainfall from sowing to the time of revision, and the initial amount of fertiliser applied. If farm logistics allow it, split or delayed application of nitrogen fertiliser is a valuable tool for management of risk
