About this listen
Welcome to Ep. 8 of Regen Radio, the podcast where we confront conventional agronomy and champion regenerative solutions that restore soil, revitalize farms, and release abundance.
Powered by SoilCraft, our mission is to lead innovation in regenerative agronomy—empowering farmers to grow food that heals both the land and its people.
In this episode, we dive into the dirty truth about phosphorus—one of the most essential yet mismanaged nutrients in modern agriculture.
💡 What You’ll Learn:
Why phosphate addiction is real—and how years of MAP (mono-ammonium phosphate) may have broken your soil’s biology
The overlooked role of phosphorus in energy and microbial function
The importance of soil testing methods (Bray, Olsen, Mehlich) and how to interpret them regeneratively
Why soft rock phosphate, when supported by biology, can outperform synthetics over time
The tragic loss of legacy phosphorus in dead soils—and how to unlock it without spending more
How mycorrhizal fungi disengage when synthetic P is overused
A balanced approach to transitional phosphorus programs using both short- and long-release strategies
🔥 Key Insights:
“It’s like discovering a hidden bank account in your soil.”
“You might be paying for MAP every year while losing calcium, biology, and long-term availability.”
“We raised phosphorus levels without applying any phosphorus—just biology.”
🌿 Whether you're in row crops, specialty crops, or soil restoration, this episode will challenge you to rethink phosphorus, availability, and your relationship with your soil’s microbial bank.
