Three of the region’s preeminent speakers for soil, food and climate change are joining together to present on Feb. 15 at Fall City.

The presentations are part of a Master Gardeners workshop, from 8 a.m. to 1:15 p.m. at The Commons at Chief Kanim Middle School (32627 SE Redmond-Fall City Road, Fall City). The speakers are aiming to address Valley farmers, gardeners and environmentalists.

At 9 a.m., Ann Biklè will present. Biklè is a biologist and environmental planner whose career spans the fields of environmental stewardship, habitat restoration and public health. She is the co-author along with her husband, David Montgomery (also a presenter), of “The Hidden Half of Nature,” a thought-provoking book about leveraging the cultivation of microbiomes to transform agriculture and medicine.

David Montgomery will speak at 10:10 a.m. A professor of environmental science writing in the Department of Earth and Space Sciences at the University of Washington, Montgomery specializes in geomorphology and has studied the way soils have shaped human civilizations both now and in the past.

Chad Kruger is the director of WSU’s Center for Sustaining Agriculture and Natural Resources (CSANR) and the Northwestern Washington Research and Extension Center (NWREC) in Mount Vernon. Kruger will present at 11:20 a.m.

The cost of the workshop is $25, and it includes coffee, tea and water. Check in begins at 8 a.m.

Sponsors include King County Master Gardeners, SnoValley Tilth and their 60 farmers, King County government, and King Conservation District.
