The front's better than the back, but both do need some work to put them into the perfect groove. In the numbers below, I folded together what I could, and listed them in front/back order.

ME 6.6/4.4: Most likely a very sandy to moderately sandy soil. It doesn't hold a great deal of resources, so testing every other year once balanced would be a good idea.

OM 1.3%/2.0%: Poor and just barely Fair, respectively. Always mulch mow, mow your fall leaves, and (given your lower ME), I'd consider stealing your neighbors' discarded leaves and applying those. Organically feed if you like.

pH 6.1/5.6: Close to good and a little low (but nothing hyper-extreme). Both could use some adjustment as your lower EC (ME) soil means that there aren't a lot of resource spots to begin with. pH tends to balance higher in that case. More under Ca, Mg, and K.

Sulfur 24/39: Normal!

Phosphorus 33/33: Quite low, and my target here would be 200. We use starter fertilizer to raise this, and just get the cheapest. They're all the same. Recommendations below.

Calcium 57%/38%: Close to optimal (but I'd like to lift this closer to 65-70%) and low respectively. We use calcitic lime, Encap, Mag-I-Cal, or Pennington Fast Lime, to raise this. In your case, it's critical not to get anything with much magnesium in it, so I might be inclined to search for Encap or Mag-I-Cal. Recommendations below.

Magnesium 20%/22%: High, but not ridiculous, and unlikely to be causing any noticeable problems in your soil. Still, I wouldn't let it go any higher, so avoid any major magnesium sources.

Potassium 2.1%/4.3%: The back is showing a bit high due to the low calcium and will adjust downward over the next year. Both are a tad low, but I've given you quite a bit to do and these can ride a year. If you'd rather do everything now, let me know and I'll fold them into the schedule.

Minor Elements: I'd love to ignore boron, but really don't recommend doing so. Iron is also mentioned below, as is copper and zinc.

Copper and Zinc: Copper is a bit low out front, zinc a bit low across the board (but particularly so in back). I think a year of mulching and mowing in leaves will help with this and I'm not going to recommend applications of copper sulfate and zinc sulfate at this time. But I do recommend retesting in a year.

Iron 50-ish: Quite low, although not deficient and not causing any problems in the plants. However, this won't produce anything resembling decent color in the lawn, particularly as the pH rises. Any time you like, apply Milorganite at bag rate to very slowly raise this.

Boron <0.2/<0.2: Deficient. While not the most important element, I'll always work to move your lawn into the most optimal range on everything. Me? I'd fix this. We use Milorganite as a carrier and 20 Mule Team Borax as the boron source. You can purchase 20 Mules at the grocery store in the laundry section. In a wheelbarrow or the like, dump the Milo. Spraying very, very lightly with water (I use a spray bottle like the kind people use to damp their clothes when they iron) will help the boron stick. Add the recommended amount of 20 Mule Team Borax and stir, spraying occasionally to get the stuff to stick to the Milo. Then apply over the recommended area. So if going for bag rate Milorganite (1 bag per 2,500 square feet), you'd add 12.5 tablespoons of 20 Mule Team Borax.

Recommendations:

August 15: Apply 3 pounds per thousand square feet of Encap or Mag-I-Cal to the front. Apply 6 pounds per thousand square feet of Encap or Mag-I-Cal to the back.

Labor Day: Apply starter fertilizer at bag rate on front and back.

September 15: Apply 5 tablespoons of 20 Mule Team Borax to both the front and the back in Milorganite carrier.

October 1: Apply starter fertilizer at bag rate on front and back.

October 15: Apply 2 pounds per thousand square feet of Encap or Mag-I-Cal to the front. Apply 3 pounds per thousand square feet of Encap or Mag-I-Cal to the back.

April 1, 2017: Apply 2 pounds per thousand square feet of Encap or Mag-I-Cal to the front. Apply 3 pounds per thousand square feet of Encap or Mag-I-Cal to the back.

May 1, 2017: Apply starter fertilizer at bag rate on front and back. Normally, this would be early. Your P levels are low enough that I'd rather set off some minor problems feeding early and get some extra phosphorus down.

Memorial Day 2017: Apply starter fertilizer at bag rate on front and back.

Labor Day 2017: Apply starter fertilizer at bag rate on front and back.
