S09E08 Deep placement of phosphorus and potassium (P&K)

Deep placement of phosphorus and potassium can improve crop nutrition and therefore improve crop competition, helping you control weeds. We talked with Professor Mike Bell from the University of QLD, who has been focused on deep placement of P&K in the northern regions, and Kurt Mayne, who has been implementing it into his operation in QLD.

Joining us on this extra-long episode of the WeedSmart Podcast was Professor Mike Bell from the University of Queensland, who shared his extensive experience of soil nutrition and more recent work on P&K deep placement in the north.

We also talked with Kurt Mayne, a grower from Rolleston, QLD, who has been implementing a deep placement regime into his operations, and heard about his recent experience with milk thistle.
