I'll try to send pictures of my lawn tomorrow .I moved into this house in November the lawn is in okay condition its better now .After all the snow melted it was waterlogged in the backyard even when it rain it was waterlogged for a few days it had to be lots of rain 2 to 3 inches down pour of rain.So on march 18 I had the lawn aerated and I put some starter fertilizer down because the people who lived there had a bag left in the garage.I also threw some johnthan green love your lawn love your soil to help with drainage water logged problem and to help the soil I did that around April 1.It seems liked it helped but I should of got the soil test sooner because that product has calcium in it and it looks like I got too much calcium.Lastly I put a pre-emergent down april 20 and I used weed killer twice first application was April 15 I have lots of dandelion and a little clover and a little grassy weed I guess that what it is but the lawn look better.The lawn still seems like its compacted I know it will get better over time you guys at houzz and the guys at bestlawn.com have helped me before with my old house its my rental property now but its the best lawn in the neighborhood now so I know you can help me with this lawn. At my new house some of the lawns in this neighborhood are in excellent condition I have my work cut out but i'm ready thanks any help would be appreciated.

Extremely nice! At the moment, I think we give you the crown for Best Soil Test of 2015, although that's subject to change. Adjustments here are minimal. Can you tell me your location and grass type, if you know it? I'm going to make recommendations for a northern lawn for starters, but may need to move things around a little if you're down south.

EC 12.1: Probably a mostly-silt soil, perhaps with some sand and/or clay. This is a nice number as it's high enough to hold a nice amount of resources but not so high that we can't change the balances as we have to.

pH 7.2: No barrier to a perfectly gorgeous lawn, although this is a little high going by the textbook. I'll discuss this under the thing that cause it--calcium, potassium, and magnesium.

OM 5.2: Very firmly in the Good range. I wouldn't mind seeing it go to Excellent (6%+), but this is hardly an emergency. Certainly consider organic feeding, and always mulch mow your fall leaves.

Sulfur 19: A very nice answer with some margin to it, which is good as I'm going to recommend adding some sulfur-based items below.

Phosphorus 136: A little lowish, kind of. My target here is 200, this is close enough that there's no deficiency. However, the lawn isn't performing quite as well as it could with more phosphorus, so I've recommended application of starter below. Get the cheapest starter fertilizer with a high second number, like 20-27-5 or 18-24-6.

Calcium 72%: A touch on the high side, but not a problem and this won't cause any issues in your lawn (except perhaps for some slight color loss). Certainly avoid calcium sources like any kind of lime for at least this year.

Magnesium 19.6%: Right at the top of the normal range, which I actually consider rather high. Not a problem, although your soil might be tighter and harder to dig than you might like. Avoid lime as it contains magnesium (dolomitic).

Potassium 2.9%: While right in normal range, I'd like to enhance this a little bit. Local garden stores or landscape places can order potassium sulfate (sulfate of potash) for you. Or it's available online. Recommendations below.

Sodium 1.2%: While a touch higher than I like to see, this is not causing a problem just yet. Sodium in higher amounts is toxic, so this does bear watching just to make sure it's not going up.

Minor Elements: All perfect. I do discuss iron below, however.

Iron 163: Well within normal range and not deficient. At your pH, however, this isn't going to produce the best color, and your color in most wet soils or using elite grasses will be tolerable at best. Application of Milorganite whenever you like will very slowly raise this, and deliver a large quantity of immediately-available iron until it binds up (which happens fast at a pH of 7.2).

Recommendations:

May 23 or so: Apply starter fertilizer at bag rate.

June 15: Apply 1 pound per thousand square feet of potassium sulfate.

September 1: Apply starter fertilizer at bag rate.

September 15: Apply 1 pound per thousand square feet of potassium sulfate.

October 1: Apply starter fertilizer at bag rate.

Sorry Saint Louis Missouri my grass type is tall fescue thanks morpheuspa

No problem! For St. Louis and fescue, the schedule above is perfect.
