Is Permaculture just bunny hugging hippy shit about growing a few vegetables in a bucket or a serious way of dealing with our planetary existential crises?
Great to see the evidence. It's still just related to farming/agroecology though - when we see the same evidence about the benefits of using PC design for health & well-being, education, livelihoods/business and governance, I'll be fully satisfied!
"The plant-extractable concentrations of soil phosphorous, potassium, magnesium, boron, and zinc were higher on permaculture sites than on conventionally fertilized soils of the control fields, which can be explained by a higher input of organic matter....." and surely also explained by the actions of the soil food web between plant roots (including crops) and soil fauna - that's what's running the cycle of OM breakdown/take up. So imo putting improvement just down to OM inputs is simplistic at best. Still great evidence tho

Yeah OM only unlikely. Compost OM works better when accompanied with cover crops. Soil cycles messed up on conventional sites too I imagine.
