Other trial notes

​This investment is designed to collect and collate data from a range of different soil types under plus and minus K fertiliser treatments to validate K responsiveness and look to ascertain if current critical K values are accurate across all soil types. The investment is also designed to demonstrate the value of tissue testing to diagnose K deficiency and validate best practice methodologies of application including banding of K which has been shown to provide benefits vs topdressing, foliar application & claying.

Colwell K in top 10 cm, 130 ppm
