These are some of the best resources I've found for anyone interested in agriculture. This list focuses on regenerative/sustainable ag, homesteading, etc. I will be updating it often.
You may notice that there's not a lot of "organic farming" specific on this list. Organic is controversial, and more of a marketing tool. There are more important things than being certified organic so don't get hung up on it.
Ponder On That is pro human and values individualism, liberty, responsibility, free markets, and rationality. A lot of resources in the sustainable ag movement do not share these values. Nonprofits and educational institutions in particular present a problem. Many of these institutions have, as the kids would say, "gone woke". Therefore I have tried my best not to include any organizations that openly identify as Marxist, collectivist, anticapitalist, antiracist, or stray to far from their core mission. If I do include them its because the knowledge the share is worth the cost. Thankfully most of the best resources are laser focused on their missions and not political activism.
