Anyone have a thought on what this grass issue looks like?

Hello,

Looking for a bit of help diagnosing a problem with a lawn. In the picture you will streaks of lighter green grass. It's surely light grass and not sun shining through the treetops. I have no idea what these are from. This part of the lawn is over a leach field. The soil isn't the best as you would expect above a leach field. So the grass that does grow isn't very robust at all. But up until this last week it was at least always the same color of green since I've been taking care of it.

what I know:
-This lightening occurred about a week after applying a fert.
-I applied the same amount as I have applied over the last 2 years for this lawn. This lightening never happened before.
-The streak patterns is 90 degrees off from the pattern I use to drop the fert.
-The lawn is watered regularly twice per week with an inground system for about 45 minutes each time.
-The most important part: the streaked sections received no different treatment or use than any other portion of the yard...but it still turned light yellow.
-The entire section in the image below receives uniform light.

Does anyone have any ideas on what this might be?

See attached image.

Thanks

Looks like iron chlorosis. Too much P and a low PH. Sulphur and Iron app after a soil test should fix it and even out the color.

Aren't the areas a little too perfectly shaped for PFB?

What's that post in the lawn that looks like it has an electrical box on it? From the picture it looks to be the electrical box for a septic pump. If that's the case I'm thinking you may have a drip emitter system which are normally installed close to the surface (12"). You maybe seeing those streaks from either high doses of chlorine down the drain or just large amounts of water.

Do you ever see water surfacing in these areas? They may not always have a smell because some systems have aerators that help break down the grey water prior to pumping it into the drip lines.

I have it to, you have a septic system or on city sewage?

First time I had it though becase I didn't put out fertilizer this spring and I know mine is the septic system

Why are you betting/guessing about anything. He already stated it is a leach field.

I missed that part of his message...

By the looks of it it is a non conventional system...maybe drip which uses the top 24" soil and evaportranspiration to get rid of the waste water. These systems are prone to failure if you are not careful.

Same here, I posted then re-read the thread.

I pretty much seen my back yard and knew right away

However my drain lines are by the old codes not new codes which are 8 feet under instead of 6 feet. Not worried about failure and as I said I didn't fertilize this spring which is the only reason I see it.

I'd say don't worry about it as of now and with the heat I wouldn't attempt fertilizer.
