I've been attempting to run a permaculture garden on a rural property in Canada for several years now (this is my third season). My property is in a second growth hardwood forest (closed canopy maple/beech) area with minimal history of human disturbance - the area was logged in the mid 19th century but has otherwise been left alone and I'm pretty sure I was the very first human being ever to work the soil here. I didn't want to deforest so I started my garden in a natural clearing that was filled mostly with wild raspberry plants. The clearing is big enough to have full sun in the garden despite closed canopy forest surrounding it.
The ground was full of huge rocks which we removed mechanically before planting. The remaining soil is very workable and seems to drain well. But it also seems incredibly nutrient poor. Almost all plants grow disease free, but very small/stunted. (Although they never seen stressed, per se, just very slow growing). Garlic bulbs that are barely bulbs, zucchinis only produce a handful of fruits a week in mid summer despite having a dozen plants, tomato plants grow tall but have exceptionally poor yield in terms of kg per plant, potato patches have so little yield that I actually harvest less than I planted, etc. I've done cover cropping with hairy vetch, cereals, etc, and always plant with compost. And been pretty good about never leaving the soil bare (always mulching), however it seems the problem is actually getting worse each year with the sizes of garlic bulbs for example getting smaller and smaller per season.
The surrounding ecosystem seems very healthy. Lots of pollinators, trees are big, native understory plants thriving, and lots of fauna including several endangered species that are otherwise quite rare in my region. We harvest maple syrup and forage wild raspberries & native flowers for herbal tea from the property and that has exceptional yield and quality, so the property as a whole seems pretty good.
Anyone have any pointers about what I'm doing wrong? Or even just some stuff to read that would be relevant to my type of climate and biome?
