I am new to this forum and am approaching my second year in implementing permaculture techniques in my garden. A little background first. I live in a typical suburb neighborhood in zone 5 (michigan), and have pretty much solid clay soil. I also sit at the bottom of sloped yards, so my yard gets all of my neighbors rainwater (great unless it is extremely slow to drain like mine). I wanted to only do a no til approach to my garden as I knew the existing soil was not good enough to plant in. So I laid cardboard down and put organic matter (including leaves, compost, horse manure, straw, and top soil) in place for my garden beds, and wood chips down for pathways. My garden area seems to suffer, I am thinking the beds are not deep enough? I have really struggled with my fruit trees and bushes. I have apple trees, pear trees, peach trees, cherry trees, blueberries, raspberries, grapes and black berries planted. All fruit plants were planted within the last couple of years. When planting I mixed in some compost with my soil, but that was it. I've noticed a lot of the leaves turn a somewhat red color throughout the entire growing season (low oxygen?), and have not been able to get raspberries established for the life of me. I concluded that I needed to get my soil tested, so last fall I finally did.
Here is what resulted:
"Soil is hard and clumpy - needs conditioning - slow to drain. PH 6.6, Hummus 1 (very low), N 60#/A (low-mod), P 75#/A (low-mod), K 140#/A (low)"
They provided some recommendations on what to do to amend the soil, and I have some ideas, but am curious any one else's experience/recommendations. Help please!
Here is an aerial photo of my garden space for reference.
