Using Soil Buffer Tests to Predict Lime Requirement – Carol McFarland: WSU Department of Crops and Soil
Different soils can require very different quantities of lime to raise soil pH. Buffer Tests is a quick method that soil test labs use for recommendation for how much lime to apply. This presentation will provide an overview of how buffer tests work, and how the different tests perform on Palouse soils. The audience will come away with an increased understanding of how to use this information on their soil test reports to better understand lime requirements on their soils.
Lime Calculator: In this hands-on mini-workshop, we will provide an overview of how to use the online lime calculator provided by WSU Extension as a decision support tool (attendees are encouraged to bring tablets, laptops, or smartphones to fully participate in this workshop).
