Abstract
The fate of various levels of phosphorus applied to a grass-legume forage mixture on a strongly P-"fixing" Gibbsihumox soil was tracked over 9 years. The status of the plots at the end of that time is shown in a photo, and the forage yield in the plots is plotted against P applied for four occasions of sampling over the period.
