RE: Which Fertilizer?
Your best bet is to take this test report with you to your Coop or farm supply and see what combinations they may have to come up with what you need. There are many combinations of fertilizer but not all stores carry all of them. the magnesium will not be in the bag mixes and you will need to get this in a separate supplement. My closest guess is about 8 bags of a 5-20-30 mix plus the Magnesium. The nitrogen seems the least problem, so you may have to lean toward the rest of the nutrients.
Good luck.
