I have permanent mounded garden beds and fields and pastures here in previous tobacco/grazing land in Central NC. I handle the two spaces differently because it’s hard to mulch 120 acres no matter how many loads Asplundh brings you.
In the gardens there’s two types of amendments: good and bad. Anything I think is good gets put on top. If you don’t mix it in it’s hard to do damage: mulch, compost, hay (no persistent broadleaf sprayed stuff - that sets you way back), ash, charcoal, whatever. Every year gets better and better. Just be patient and go for the small wins. Keep it fun so you keep it up and don’t be discouraged if some years some things fail. I don’t overreact with pests or deficiencies and usually they correct themself.
Big scale is so different, spread as much good stuff as you can, but also don’t be afraid to do a few applications of P K when you get started. Bring some levels back up and then stop “mining” the soil, and it starts to cycle again. Keep in mind how abused most land currently is. You’re not starting from Step 1, you’re at Step -100.
Another thing I want to mention is very strategic sub soiling. You can do it wrong but if you do it right it does so much good. It’s a good alternative to swales if you don’t want to spend the rest of your life making turns on a tractor.
Y’all are loving Mother Nature and bringing life back into the world. Just keep going!
