You can irrigate or not irrigate as it pleases you, although for this year I'd irrigate at least the lawn if possible. Your grass is young. After that, however you play it is up to you! This year, I'm not irrigating (except the gardens, of course).

Overall, the test isn't bad. For the most part, I rolled the lawn and outlot together as they're very similar results. Where they differ in an important way, I was careful to note that. In the future, you can combine these tests.

ME 20-something: Normally, this would speak to a heavier soil, but in your case the excessive calcium is pushing this answer up. I'm going to call your soil around an ME of 15, or what would usually be a pretty good loam.

pH 7.1: A little high, but nothing that'll cause any problems. It will tend to limit iron uptake, so use of Milorganite is a good idea. Other than that, your grasses (and most plants) won't have too much trouble with this, although I'd avoid acid-loving plants in the gardens.

Organic Matter 3, 4.5: Fair and Good, respectively, both of which are great given your ME. Certainly mulch mow, mow all your fall leaves, and feed organically if you wish, but you don't need to make any special effort.

Sulfur 20, 9: Both are perfectly acceptable answers. The 9 might be a little low, but although sulfur is required, it's not required in huge amounts at any one time. That won't cause deficiency.

Phosphorus 58, 81: Very close answers (for all they look different) and both rather low for this particular test. At a pH of 7.1, my target would be about 220. We use standard starter fertilizer to fix this, and just get the cheapest. They're all about the same. Recommendations below.

Calcium 82%-ish: Very high, but not a problem. Calcium's not toxic under normal circumstances and lawns can grow in limestone chips. It's setting off your higher pH in part, but there's nothing we can really do about it anyway. Avoid major calcium sources.

Magnesium 12%-ish: It looks textbook perfect, but it's actually rather high--it's just somewhat suppressed by the high Ca. Avoid magnesium sources.

Potassium 0.8%-ish: It looks very low, but it isn't as low as it looks (the calcium and magnesium are both depressing this answer). Still, it is lower than I would like to see, optimally speaking. While technically optional, I'd do the following. We use potassium sulfate (sulfate of potash) to correct this, which you can sometimes get at garden or landscape stores, or have them order it for you. Or you can get it online. Recommendations below.

Minor Elements: Boron is off in the Lawn area, and discussed below. Iron is also mentioned.

Iron 100-ish: Absolutely not a problem, but not going to produce good color at your pH. Whenever you wish, apply Milorganite at the bag rate to very slowly raise this.

Boron 0.32, 0.74: Optimal on the Outlot portion, low on the lawn. 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 10 tablespoons of 20 Mule Team Borax.

Recommendations:

August 15: (optional but recommended) Apply 4 tablespoons of 20 Mule Team Borax per thousand square feet in Milorganite carrier.

September 1: Apply starter fertilizer at the bag rate.

September 15: (optional but recommended) Apply 3 pounds per thousand square feet of potassium sulfate.

October 1: Apply starter fertilizer at the bag rate.

October 15: (optional but recommended) Apply 3 pounds per thousand square feet of potassium sulfate.

May 30, 2017: Apply starter fertilizer at the bag rate.
