This article from Edible Magazine features Bob Quinn of Kamut International, who spoke at the Edible Institute 2020 conference at La Fonda on Feb 19, 2020.  Quoting Quinn, Edible defines regenerative agriculture:

So what is regenerative agriculture? Though particular features vary among its practitioners, it first and foremost requires food producers to nourish the soil, rather than mine, deplete, or even destroy it, as happens in industrial agriculture. Chemical herbicides and pesticides common in industrial practice can kill organisms in soil, leaving the soil a nearly lifeless medium reliant on artificial nutrients and thus creating an endless, toxic cycle.

Quinn also emphasizes the importance of real organic practices as opposed to “Big Organic.”

As a practitioner and public advocate of organic agriculture, Quinn actively resists the advance of large-scale organic agriculture, or “Big Organic,” which he argues in his book, Grain by Grain: A Quest to Revive Ancient Wheat, Rural Jobs, and Healthy Food, “has mostly gone the extractive commodity route.”  To food corporations and other businesses, large and small, that are trying to get into organics, Quinn asks them to assess whether their businesses extract value from communities for commodities or return value to communities. To Quinn, thinking in terms of commodities cannot be organic. “Organic—real organic—requires a whole systems approach,” he insists, “with value regenerated at every stage in the process.”
