Foundations Series #5: Reading the Soil: Agronomy, Soil Testing & Crop Health with Lee Briese
In this episode, agronomist and crop consultant Lee Briese shares his practical approach to understanding and managing soil health. Drawing from years of field experience working with farmers, Lee explains why reading the soil requires more than just lab reports — it involves observation, interpretation, and understanding how chemical, physical, and biological properties interact. Lee discusses why he often prioritizes chemical soil analysis when making management decisions, and how tools like soil testing, visual assessment, and field experience help diagnose what crops truly need. He also emphasizes the importance of soil structure and aggregation, and why physically interacting with the soil — touching it, smelling it, and walking the land — provides insights that lab data alone cannot. The conversation explores how experienced agronomists approach soil much like doctors approach the human body: looking at multiple indicators together to identify underlying issues and guide effective interventions. Originally released as Episode 87, this conversation remains a valuable reminder that successful crop management starts with careful observation, sound data, and a holistic understanding of the soil system.
