WEOC vs. Copilot: copied and pasted. The "bottom line" portion is exactly what I had in my own mind: someone's trying to sell something. Be careful who you listen to and always test the messaging you allow into your thought process. #WEOC #Skeptic #LookingForAnswers #FAFO From Copitot: Hot take: WEOC is wildly overrated as a soil “health” metric. Yeah, it’s flashy. It moves fast. It reacts to management. It makes great conference slides. But here’s the uncomfortable truth nobody selling tests wants to say out loud: • WEOC is labile to the point of chaos. A warm week, a rain event, or a mower pass can swing it. That’s not “sensitivity”—that’s volatility. • There’s no standard method. Change the extraction ratio, shaking time, or pre‑treatment and you get a different number. If pH behaved like this, we’d riot. • Context dominates the signal. Climate, texture, mineralogy, and land use can overshadow management. A “high” WEOC in Iowa might be meaningless in Arizona. • It doesn’t predict yield. Zero validated agronomic thresholds. Zero decision‑ready guidance. It’s a research metric masquerading as a management tool. • It’s not uniquely special. POXC, HWEOC, MBC, respiration—they all capture different slices of labile C. WEOC isn’t the king; it’s just one more contestant. • It’s a tiny fraction of SOM. Treating WEOC like a master indicator is like judging a whole farm by one fencepost. Bottom line: WEOC is useful, but the hype is outpacing the science. If someone tells you it’s the soil health metric, they’re selling something—or oversimplifying a complex system.
