Biochar isn’t a single material—pyrolysis temp and feedstock drive huge differences. Wood charred at 550 °C behaves nothing like manure‑based biochar at 350 °C, yet both wear the same label. That variability kills any blanket soil‑improvement claim. The chemistry is real; the right context is everything. How do you tailor biochar use without over‑generalizing? #CarbonCapture #SustainableMaterials #Decarbonization #EcoTech
