Your Soil Has Nutrients But Your Crops Are Still Starving Here's Why

Some farmers are sitting on thousands of pounds of nutrients and their crops are still starving. Why? Because the missing link isn’t fertilizer. It’s function. In this episode of Soil Talks™ Podcast, we sit down with Tom Vander Heiden, GM of Ag at ST Biologicals, to unpack what most soil conversations completely ignore: the living systems that turn nutrients into yield. This isn’t theory. This is what shows up when you slow down, dig in, and actually observe the soil. In this conversation, we cover: Why soil tests often miss the most important part of the equation The biology gap (high nutrient soil, hungry plants) How carbonic acid unlocks minerals already in your field Why manure diversity worked before it was called regenerative Why you don’t fix fields at 60 MPH, you fix them with a shovel One line from this episode says it all: “The greatest limiting factor of yield… is the farmer’s shadow.” If you’re serious about profitability, resilience, and building a farm your kids actually want to inherit this conversation will change how you look at soil.
