Liming and pH: Timing, economics, materials, and more

UMN Extension Nutrient Management Podcast

In this episode of the Nutrient Management Podcast, our panelists discuss liming in detail. What kind of variation is there in liming recommendations?

What should growers know about selecting liming materials? What other bits of advice do our panelists recommend?
