For decades, agriculture has treated soil like a chemical system.
Add fertilizer to correct deficiencies. Increase yield.
But what if the real problem isn’t nutrients, it’s biology?
In this episode of Soil Talks Podcast, Brandon Kail sits down with Jon Stika, author of A Soil Owner’s Manual and a former NRCS agronomist with over 30 years of experience studying soil health and regenerative agriculture systems.
Together, they unpack one of the most important shifts happening in modern farming:
Soil is not a chemical system.
Soil is a biological system.
John explains why the Green Revolution pushed agriculture toward fertilizer dependency, how soil aggregates create habitat for billions of organisms, and why rebuilding soil biology may be the most profitable path forward for farmers.
Inside this conversation:
• Why modern agriculture became dependent on fertilizer
• The hidden soil biology beneath every field
• Why soil tests were built for degraded systems
• How soil aggregates control water infiltration and nutrient cycling
• Why yield per acre can be a misleading metric
• The transition period when moving toward regenerative agriculture
• How soil health affects nutrient density in food
If agriculture is going to remain profitable and resilient, the conversation must move beyond inputs and toward restoring the biological systems that make soil function.
Listen to understand why many farmers are shifting from a chemistry-first model to a biology-first approach.
