Season 1
Liming and pH: Timing, economics, materials, and more
In this episode of the Nutrient Management Podcast, our panelists discuss liming in detail. What kind of variation is there in liming recommendations? Since pH changes aren’t instant, when is the best time to apply limestone? Is lime application economically justified, and in what circumstances? What should growers know about selecting liming materials? What other bits of advice do our panelists recommend?
Guests:
- John Jones, Soil Fertility, plant nutrition, and nutrient management research, University of Illinois Urbana-Champaign, (Urbana-Champaign, Il)
- Jeff Vetsch, U of M researcher (Waseca)
- Daniel Kaiser, Extension nutrient management specialist (St. Paul)
