Be sure to get in line in the "soil test interpretation queue" thread. That's how they keep track on who's next in line. You'll see that thread a few down from this one.

Re: Central MN soil test
That's a somewhat sandy soil with sorta-crappy OM numbers. For 300 sq ft, I'd use peat moss supplementation for holes dug for shrubs and peat moss or compost on the lawn area, and keep it up.
The Calcium is perfect but the Magnesium is too high. You could leave it alone and use Milorganite for Iron/Nitrogen. Also work in some Sulfur into planting holes - it will most like do nothing for the higher-pH, but you're pretty short on Sulfur. Alternatively, you could supplement with Gypsum which will do two things: (1) raise the Sulfur through Sulfates, and (2) displace some Magnesium with Calcium (good for you).
The Phosphorus is fine, and the Potassium low. You can get few lbs of Sulfate of Potash (SOP, 0-0-50) and apply at 2 lbs/K monthly.
The raw Iron number is OK, but it's not available at that pH. Hence the Milorganite, which is also a good Nitrogen supplier.
In the micro’s, it’s Boron and Copper. Get Twenty Mule Team Laundry Soap (grocery) and Copper Sulfate (Amazon/EBay), and apply each at three tablespoons/K every 60 days. Read the Micronutrient Application Guide for application specifics.
