Plain text source: 
Potassium was applied at rates between zero and 100 kg/ha IBS and banded in the forms of MOP and compound NPK product (Vigour)... Key messages - There were no significant differences between K sources or rates at this trial, despite soil test model predictions of high K response - Canola did not respond to high P application at this site in the absence of Nitrogen - The site was highly N responsive, although the N use efficiency suggests leaching was moderate... Available water capacity computed for each of the specified depth increments..
