Highly interesting and can we get some literature links please. Shared the video and subscribed to the garden blog. Humus debunked.
Thank you.
Thank you ❄️💚🙃
Thank you for explaining soil science in terms simple enough for anyone to understand! I enjoy watching your videos then being able to have a more informed discussion with my agronomist husband who has spent a lot of his 40+ years of consulting debunking “snake oil” products that are marketed to his clients.
Last spring I started adding a scoop of fulvic acid into my foliar spray because of the claim that it helps penetrate into the plant cells. I’m not declaring that it works for sure but I had pretty good results last year where the deer didn’t interfere.
