Soil Acidity and Liming on the Palouse - what we know in 2020
Dr. Haiying Tao Assistant Professor and Nutrient Management Specialist in the Department of Crops and Soil Sciences: WSU Pullman
Soil Acidity 101-
Worldwide, soil acidification is a major soil health problem limiting crop yield and quality. In the past decade, soil acidification has become a growing concern for dryland crop production in the Pacific Northwest. We will discuss the causes of soil acidification, the effects of soil acidification on soil health and crop yield and quality, and methods of amelioration.
Dr. Rick Engel Professor in the Land Resources and Environmental Science Department: Montana State University, Bozeman
Soil acidification of cultivated fields in semiarid Montana: adaptation and challenges to remediation-
Farmers in parts of Montana are experiencing crop growth reductions or complete crop failures as a result of soil acidification and Al toxicity. This presentation will discuss results from recently initiated onfarm trials that include sugar beet lime applications, seedplaced P and cultivar selection; and to discuss some of the challenges to soil acidity remediation in Montana.
Dr. Tim Paulitz USDA-ARS Research Plant Pathologist, Pullman
Co-authors: Daniel Schlatter, Chuntao Yin, Christina Hagerty and Kurt Schroeder
Soil pH and Soil Microbes: Cause and Effect-
We will discuss how liming affects bacterial communities in the soil, especially those involved in nitrification which produces the low pH. These results are from liming trials in WA, OR and ID. We also describe bacterial communities that are adapted to acid soil layers in direct-seed systems. It is critical to understand the role of soil microbes to develop management strategies for this long term problem of soil acidity.
Dr. Tim Murray Professor and Chair, Department of Plant Pathology, WSU Pullman
Effects of Soil Acidity on Wheat Diseases-
Dr. Murray will describe the effect of soil acidity on several wheat diseases of importance in the Inland Pacific Northwest and ways to mitigate its impact. He will describe preliminary results of research using alternative liming products such as fly ash and biochar to mitigate the impact of pH on disease, mineral nutrition, and aluminum toxicity.
Dr. Dave Huggins: Research Soil Scientist with USDA-ARS Sustainable Agroecosystems Research Unit
Long-term Soil Acidification, Obvious and Hidden Dangers
What we know, dont know, and progress toward managing soil pH.
Dr. Kurt Schroeder: Assistant Professor and Cropping Systems Agronomist at University of Idaho, Moscow
Managing soil acidification in cereal-based cropping systems-
This presentation will provide an update on a long-term study in northern Idaho to study the impact of liming on crop performance and changes in soil chemistry. Lime application is costly, but the benefits will be realized over multiple years. This project is just entering its fourth year and a summary of returns on this capital investment will be discussed. In addition to liming research, there will be an update on screening for aluminum tolerance in wheat.
Jim Durfey: Instructor in Department of Crop and Soil Science at WSU, Pullman
The application question-
This presentation will discuss addressing the logistics of lime application. Various materials lend themselves to equipment considerations as an important component of any decision to apply lime.
Soil Acidity Management on the Farm
Palouse Farmers Josh Jones and Seth Millhorn will each share their experience with the legacy of soil acidity on their farm.
The Effects of Acidic Conditions on Palouse Crops
This session will feature a hands-on activity using live plants to demonstrate the effects of soil acidity on common Palouse crops
This workshop is eligible for 7 CCA credits
