Or course, it is possible to start with the right plants, but it is a longer process.
The test suggest your soil is slightly acidic and is very low on macronutrients. The acid usually comes from decomposition, and it is easier to see in moist soils. The lack of nitrogen is usually because the mechanism of reposition is not there, or maybe it is decomposing woody material, which needs much nitrogen. I mean, if this is a prairy where ruminants used to defecate, the system is adapted to this, but the ruminants are not there anymore, so it lacks manure. Or a farmer used to apply manure, which is the same, at the farmer's extra work. Or maybe it had many legumes species that were supressed for a lawn.
So, your soil is decomposing fast, but you are not replenishing it's nutrients, this is what the test is saying. And they suggest you to apply 10-10-10 and some lime, if you wish to grow the usual stuff in a market garden. The problem with applying manure is that once you take yourself the role of fertilizer, that's yours, you have to keep fertilizing. Forever. (This is how our grandparents grew stuff, not a big deal unless you are relying on external inputs).
Now, you want to use plants for building soil. Excellent. You need plants adapted to the current conditions of your soil, which are mostly weeds, and some rustic shrubs, plants that do not require fertilization and grow fast. These will create some organic material, increase the microbial population and prepare conditions for more demanding plants. When the ecosystem is at its apex, you prune it and make way for the next stage. This is how sintropic gardening works. But it takes years.
With a good compost you can skip the first years and start growing at fertile prairy levels.
Both are valid methods.
