A WSU Extension Workshop brought to you by The Farmers Network
Join us for the opportunity to hear from the regional experts on soil acidity in Eastern Washington and Northern Idaho, as they share their work. Registration will open at 7:45 and the last event will conclude at 3:45. The workshop agenda will include:
-Effect of Soil Acidity on Wheat Diseases
Dr. Tim Murray Professor and Extension Plant Pathologist:
Soil acidity directly affects crops, pathogens, and mineral nutrition. Dr. Murray will describe what we know about the effect of soil pH on several soilborne wheat diseases. He will also discuss ways to mitigate the impacts of soil acidity and associated pathogens.
-Advances in liming and root-acid soil research
Dr. Bill Pan Professor, Scientist, and Extension Specialist in the Department of Crops and Soil Sciences:
Anthropogenic soil acidification continues to be documented in the inland PNW. Novel liming approaches will be required to neutralize subsurface acidity. We are experimenting with organic-lime mixtures using locally available straw pulping, lignin-rich coproduct. He will share his high resolution imagery of crop root growth and dieback in amended and unamended acid soil.
Dr. Haiying Tao Assistant Professor and Nutrient Management Specialist in the Department of Crops and Soil Sciences:
Stratified soil acidification in no-till systems is difficult to address because it can take many years for surface-applied lime to move to the acidified layer. WSU researchers have found an effective strategy to address this problem. Dr. Tao will present how mixing lime materials with lignin-containing black liquor can help move into and neutralize the acidified zone.
-How does your wheat grow?
Dr. Paul Carter Associate Professor and County Extension Director:
Dr. Carter will report the extent of soil acidification issues from his soil survey and work with over 30 on-farm research trials conducted in Columbia County. The presentation will focus on the relationship between soil acidity and liming effects on essential soil nutrient interactions, and crop deficiency symptoms as well as agronomic effects. Paul will introduce best practices for measuring pH in the field and talk about opportunities for future work.
-Soil pH and microbes how pH affects whos there and what they do
Dr. Lynne Carpenter-Boggs Professor in the Department of Crops and Soil Sciences:
Soil pH has a strong influence on the microbial community. In this presentation Dr. Carpenter-Boggs will discuss the role of microbes in soil health and functioning. The presentation will focus on how soil microbial communities and activities change as soil pH decreases, and how this influences soil fertility, health, and functioning.
-Liming exercise: agronomic strategy and economic risk and return assessment
Carol McFarland: Research Associate in Cropping Systems, in the Department of Crop and Soil Science
Doug Finkelnburg: Area Extension Educator, Cropping Systems
This interactive session will provide an opportunity to build and share knowledge within the audience on the topic of soil pH by discussing and sharing ideas for management approaches to various case studies.
-Soil Acidity and Liming: In the Field
Dr. Kurt Schroeder: Assistant Professor and Cropping Systems Agronomist
Dr. Schroeder will discuss the results from his years of working with multiple lime products in on-farm liming trials around the Palouse region. The presentation will include the implications for management of various crop types and varieties
-Soils Influence on Herbicide Persistence, Activity, and Movement
Rachel Zuger: Research Associate in Weed Science in the Department of Crop and Soil Science
Soil characteristics such as texture, organic matter, CEC, and pH can effect herbicide activity, effectiveness, and persistence. Soil properties should be considered when determining herbicide rates, application timing and placement, varieties, and herbicide plantback restriction. Knowing individual field soil types and history can help prevent potential problems.
Lunch and light refreshments are included with registration.
This workshop is eligible for 7 CCA credits
