Garden Success — Soil Science, Rice & Water: A Conversation with Dr. Jake Mowrer

This week on Garden Success, host Stephen Brueggerhoff sits down with Dr. Jake Mowrer, the newly appointed director of Texas A&M AgriLife Extension's Soil, Water and Forage Testing Laboratory, for a deep dive into everything happening beneath our feet. Jake shares how he stepped into the lab director role after 11 years as a soil fertility and water resource management professor (and 15 years in Extension work in Georgia before that), and explains why "don't guess, soil test" should be every gardener's and farmer's starting point. The conversation ranges from the philosophy of "soil function" versus the trendy NRCS term "soil health," to Texas's declining rice acreage and Jake's cutting-edge research showing that intermittent flooding can cut rice irrigation water by 25% with zero yield loss — a potential game-changer for water-strapped Texas rice farmers. Along the way: the surprising size of the soil microbiome, why extension work touches far more of daily life than most people realize, and a candid look at what did and didn't work in Jake's multi-year solarization trials for weed and nematode control (spoiler: mustard-based biofumigation is winning out). Two callers phone in with real backyard battles: Jennifer wrestles with Bermuda grass overtaking a flower bed and asks about solarizing with plastic, and Rose seeks mulch strategies to keep lawn grass from creeping into her front garden bed. Jake and Stephen offer practical, science-backed advice for both. Plus: a reminder about next Thursday's new monthly segment, Ask the Plant Doctor, featuring the Texas Plant Disease Diagnostic Laboratory, and a plug for Stephen's free native-plant landscape design talk on July 18th at the Bryan library.
