What ? This is well-supported unless you have been sadly influenced by the brainwashing of corrupt American Agricorpos - who btw do a terrific job of FUD & misinformation. I even learned about the benefits of organic farming in high-school biology class.
"organic farming generally had higher soil organic matter, lower nutrient losses per hectare, lower energy requirements and generally better biodiversity outcomes"

Actually, there are dozens of papers. The research is extremely supported for sustainable agriculture with the corresponding caveat of lower yields like I mentioned. No idea how you got "deeply unsupported".
