Show Notes

What should you consider when choosing a potassium source?

In this episode, host Dr. Alan Blaylock is joined by David Holden, owner of Holden Research and Consulting, to explore how crop needs, soil properties, water source and the nutrients supplied alongside potassium can affect how well a particular source fits into a system. They compare potassium chloride (MOP) and potassium sulfate (SOP), discuss why chloride can create challenges for certain crops and explain what growers should think about when evaluating each source.

They also explore how potassium rate, timing and placement can align with crop demand, why potassium availability matters as crops develop and how irrigation can influence the source you select. The conversation offers practical considerations for selecting and evaluating potassium sources, including potassium chloride, potassium sulfate, potassium thiosulfate and potassium nitrate.
