MSU Extension to host soil acidity and soil health workshop in Fort Benton on Feb. 27

BOZEMAN — The Chouteau County Soil Acidity Working Group has organized a soil acidity and soil health workshop at the Fort Benton Ag Center, 1205 20th St., on Feb. 27, in cooperation with Montana State University Extension, the Chouteau County Conservation District, Big Sandy Conservation District and the U.S. Department of Agriculture Natural Resource Conservation Service.

MSU Extension will co-host a soil acidity and soil health workshop at the Fort Benton Ag Center on Feb. 27.

Registration for the workshop will begin at 9:30 a.m., with presentations beginning at 10 a.m.

Most agricultural soils in Montana have near-neutral to alkaline conditions with surface soil at pH 6.5 to 8, according to Clain Jones, a soil fertility specialist with MSU Extension. Some areas of Montana, however, have developed acidic soil layers in the seeding zone, which consists of about the top 6 inches of soil, Jones said. Speakers at the conference will address the issues surrounding increasing soil acidity.

The morning presentations will include a producer report and presentations from the USDA Natural Resource Conservation Service, Chouteau County Conservation District, MSU researchers and MSU Extension.

The afternoon programs will all be via teleconference, and will include soil specialists from Washington State and North Dakota.

A brief Chouteau County Soil Acidity Working Group meeting will follow the workshop.

Presentations will include:

“Identifying Soil Acidity in your Fields,” Kent Squires and Bill Summers, Geraldine, producers.

“Identifying Soil Acidity Issues when Looking at Soil Tests,” Marni Thompson, NRCS resource conservationist.

Chouteau County Conservation District update, Dale Krause, ag consultant and certified crop adviser for Chouteau County Conservation District. Krause will update producers on the CCCD Cover Crop Acidity project.

“Preventing Acidification,” Clain Jones, MSU Extension soil fertility specialist.

“Soil Acidity Tolerance in Cereal Grain Varieties,” Jason Cook, MSU plant sciences and plant pathology.

“Soil Acidity and Soil Health,” Jon Stika, Dickinson, North Dakota, research and extension center agronomist, via teleconference. Stika will cover increasing soil organic matter and discuss how improving soil biology can assist with soil acidity.

“Lime Materials and Application,” Dave Huggins, USDA Agricultural Research Service in Washington state, via teleconference. Huggins will discuss options for choosing lime materials, as well as considerations such as particle size and percent calcium carbonate. The differences between pH and buffer pH will also be addressed.

“Managing Soil Acidity in No-Till Systems,” Dave Franzen, Extension soil specialist at North Dakota State University, via teleconference. Franzen will discuss the importance of no-till and drawbacks to deep tillage. He will also cover why and how soil acidity develops and cover liming material success of surface lime applications in no-till studies.

Funding for the workshop is thanks to an MSU grant from USDA’s Western Sustainable Agriculture Research and Education program, the Chouteau County Extension office and the Chouteau County Conservation District. Lunch will be provided.
