Hi all,
I'm located in Vancouver, WA 98682, I believe zone 8b. My property is sloped East/West, 5 acres, old pasture land with very few trees. We have thick hard clay, filled with volcanic rocks, very hard to dig.
There are 3 tests on the attachment. The first is labeled ORC. This is the unamended pasture land that I'm turning into a orchard. I've been putting wood chips down, so it's progressing.
The second is Veg, my vegetable garden, about 1000 sq ft, fenced.
The third is HM. This is a sample from a giant mound of composted horse manure next door. I use it as amendment. Lately, to avoid digging the clay, I've been placing bushes and small trees in the ORC directly onto the broad forked pasture and burying in the manure. I have also used it as soil in raised beds.
My questions are-
1. Do I need to add sulfur? I've been watching Living Web Farms videos on Youtube and checked out Dan Kittredge. He recommends 75 ppm sulfur.
2. I'm guessing that both the ORC and HM need gypsum for Calcium and Sulfur?
3. Should I use potassium sulfate in Veg?
4. rock phosphate along with epsom salts and gypsum in ORC?
5. The HM is a free, abundant resource. How would one amend in the future to be able to directly apply as a complete mineral source?
I have 9 hens so I have access to chicken manure too.
Any other feedback or observations is appreciated.
Thanks again,
Mike
