Great little film discussing this subject. During the end they touch on breeding perennials that are better at extracting the amounts of phosphorous already in the soils. But even so in the long run we’d need to extract it from human waste because of our current infrastructure with people leaving the countryside for the cities.
Good old Concord and Niagara sell seem to sell the best; they are both old varieties. Sunbelt and King of the North also do well. Some wine varieties from Cornel University are the ones I haven’t cloned yet. Actually, I haven’t paid much attention, the patents may have already expired on them. I have a very nice wild one too, but they don’t sell very well. To clone them I prepare a bed and cover it with clear plastic and just stick the cuttings through the plastic, not at all how it is supposed to be done but it works at about a 50% rate and is easy and cheap to do.
Oh, that’s a neat idea! I wonder if that would work for me? I need to figure out some way to keep in moisture if I’m gonna get things to propagate. (Laugh.) Do you water them, or just leave them there for a few weeks?
Page preparing the launch of Harriet Mella Mycorrhizae course with a long interview of the Author, and then a 10 minutes, condensed video on soil life dynamics in relation with microbiology.
That last video is quite consistant with Olivier Husson’and co-researchers perspective on the soil life regeneration curve (as developped there, in particular from 26’30”, in French sorry… )- though Harriet breaks it down in more easily digestible material for non specialists.

Not a video, but I was invited on @ShaneS podcast : couple nuggets in there regarding what adaptation means for ex, my projects, how the francophone PEPs group us developing, our European GTS gathering in Croatia…
I found this to be an interesting and useful reality check:
It’s helpful to know some of the important challenges that can face a person planning to do homesteading. (I had already thought of the challenge of getting older and less physically able — that’s one of the reasons adapting plants to need less of my time each generation appeals so much to me!)

I leave them there for a whole season and yes, I water them. Keeping them damp especially at first is very important. I water on top of the plastic, and it soaks in trough the holes made when I stuck the cuttings through. I think it’s good if you can, to keep the ground warmer that the air at first but later not, so shade or mulch as best you can once they start growing new leaves. I take the plastic off with scissors in fall or sooner and replace with mulch. Any still alive the next spring are ready to pot up and sell or to transplant.

Sounds like a good system! 
Growing from seed pulp from localized trees, very diverse genetics. I like!!
“Melanoma is often associated with beaches and sunbathing, but our findings suggest that agricultural environments may also play a role,” she said. “And this isn’t just about farmers. Entire communities living near agriculture, people who never set foot in a field, may still be at risk.
The usual suspect — sunlight — was considered as a part of the study. But even after adjusting for ultraviolet radiation in Pennsylvania and socioeconomic factors, two patterns stood out: Counties with more cultivated cropland and those with higher herbicide use had significantly higher melanoma rates.
‘Pesticides and herbicides are designed to alter biological systems,’ said Eugene Lengerich, emeritus professor of public health sciences at Penn State and senior author on the paper. ‘Some of those same mechanisms, like increasing photosensitivity or causing oxidative stress, could theoretically contribute to melanoma development.’”
Just another reason in favor of low-input ag.
(Not a video, but I wasn’t sure where else to put it.)

Interesting short video about the carrots industry
Really awesome interview about the chinampas!
He is collecting wild edibles respectfully and even finds some wild garlic!
