Why Your Fertilizer Isn’t Working (And What Soil Health Has To Do With It) | AG & Culture Podcast Ep. 3Farmers and homeowners spend billions on fertilizer every year.So why are so many seeing less return on the same inputs?In Episode 3 of the AG & Culture Podcast, Mike Usry and Joseph Boehm break down one of the biggest misconceptions in modern agriculture: fertilizer isn’t the problem — but it’s also not the solution.Drawing from decades of soil study and real-world experience, Mike explains:• Why over-reliance on NPK (Nitrogen, Phosphorus, Potassium) leads to diminishing returns• What fertilizer actually is — and what it isn’t• The difference between macro nutrients and trace minerals• Why carbon is the most ignored element in soil health• How synthetic fertilizers affect soil pH and salinity• The “soil engine” analogy — microbes vs. fuel• What over-fertilization really does underground• How to revitalize depleted soil• Why monocropping damages ecosystems• How long land should rest to recover• The difference between passive rest and active restoration• The balance between synthetic efficiency and regenerative systemsMike also addresses whether soil becomes “addicted” to fertilizer and explains why the real issue isn’t chemical dependence — it’s biological imbalance.This episode challenges the idea that more fertilizer equals more production and instead focuses on the unseen world beneath your feet: the soil microbiome.If you’re a:– Farmer– Rancher– Home gardener– Lawn care professional– Homesteader– Or just someone curious about food systemsThis conversation will change the way you think about fertilizer forever.Coming Up Next: Episode 4 — The Power of CarbonListen now and subscribe for deeper conversations on agriculture, soil biology, regenerative systems, and the cultural roots of food.
