In this episode of the Root Cause Podcast, host Kaleb Dinwiddie welcomes David Olson of Sustainable Growing Solutions and Austin Cisneros of Elevate Ag for a deep dive into soil biology, plant nutrition, and regenerative farming practices. Drawing on decades of experience, David explains how healthy microbial communities drive nutrient availability, improve plant resilience, reduce fertilizer dependency, and help farmers manage pest and disease pressure naturally. The conversation also explores the value of sap analysis as a real-time tool for understanding plant health, optimizing fertility programs, and making more informed management decisions. Practical, data-driven, and packed with insights, this episode highlights how biology can improve profitability while making farming more sustainable and enjoyable.
