Ep 10: Dr. Andrew McGowan

What this episode covers

What is soil really doing beneath the surface?In this episode of How We Grow, Chad talks with Dr. Andrew McGowan, a soil scientist, agronomist, and member of Rosy Soil’s Soil Advisory Board. Andrew also works at Terradot, where he helps lead field trials and deployments focused on enhanced rock weathering and carbon removal.Andrew breaks down why soil is much more than “dirt,” how growers can make better sense of soil tests, and why simple observations — like digging a hole — can reveal so much about plant performance.They also talk about where growers can overcomplicate soil data, how to test new products without jumping in too fast, and why replicated field trials are so important for separating real value from hype.Later, Andrew explains enhanced rock weathering: how crushed rock can help remove CO2 from the atmosphere while potentially supporting soil pH, calcium, magnesium, and silica levels.A practical conversation on soil health, smarter growing decisions, and the future of carbon removal in agriculture.Links & ResourcesRosy Soil: https://www.rosysoil.com/Terradot: https://terradot.earth/Kansas State Agronomy: https://www.agronomy.k-state.edu/USDA NRCS Web Soil Survey: https://websoilsurvey.nrcs.usda.gov/
