For some reason I can't add attachments anymore. So I have entered the code from a Toolbox that contains irrigation rules that I created at the Apsim Training Course on 17-18 Nov 2009. Just add more features to these ones.

The irrigation rules in the GUI are not really good enough for users. Rather then having to build ones for every new user who asks, we should probably provide some good useful ones for them in the toolbox. Things they usually ask for are things like, allowing the user to enter an "irrigation cycle" (this is the time taken for farmer to move his irrigation equipment around each of his paddock. This should restrict how many days you can have between irrigation). Also triggering irrigation based on sw deficit, also setting the amount of irrigation to apply to be the sw deficit so that it will vary the amount of irrigation each time.
