Hello there ;-)
About 1.5 years ago, I installed a roll-out lawn that has established well.
At the beginning of July, I decided to aerate, overseed, and fertilize it a bit (I fertilize regularly).
I have always used a natural fertilizer from the company Schwab. However, for the last fertilizing, I used an NPK fertilizer from Eurogreen.
I aerated using the Einhell electric aerator.
Now, I have severe patchiness, partly white in color. I can't see any fungal growth.
In these areas, the grass leaves are also thinner than in the still (lush) green parts.
Here are some photos:

What happened here?
Overfertilized?
Incorrect overseeding with a less durable seed mix?
I would appreciate your assessment.

Hello,
you can see a possible answer in the picture itself. Part of the lawn is in the shade and still looks good there. It’s the same for us. We have an area in the garden that gets full sun from sunrise to sunset. You can’t compensate with extra watering there, and the grass burns while just 2m (6.5 ft) away it looks much better.
By the way: I also use the Schwab fertilizer; it’s still the best I’ve found to date.
Best regards,
Andreas

Alessandro22 Jul 2022 11:14I understand everything. However, it only applies to my situation to a limited extent.
What confuses me is that in the areas where the grass burns, the grass blades are much thinner than in the areas where it stays green.
There it is also not resistant to foot traffic.
I have overseeded evenly. But in the bare spots, it seems like only these fine-leaved grasses are growing.
All the thin grasses have burned, while the thicker ones remain green:

There is a lack of water. It is possible that the soil in these spots absorbs water less effectively (keyword: hydrophobicity), is exposed to sunlight for longer periods, or there are reflections from windows or similar sources.
@Alessandro, did you mix the seed thoroughly beforehand? It is usually a blend. In (almost) all lawns, there is also annual meadow grass (Poa annua). This grass turns brown very quickly, just like all shallow-rooted grasses.
Currently, almost every lawn has some dry patches. Not as severe as in the pictures, but they are present.
The only option is intensive irrigation…

Alessandro22 Jul 2022 12:14I aerated and lightly sanded those areas.
I also hand-pulled the Poa annua (at least in the larger spots) and overseeded those spots. However, that was done several months ago.
By the way, I used the "dream lawn" seed mix from Eurogreen for overseeding, so it's a rather high-quality product.

After watering yesterday, it looks like this (so much better).
Still, I don’t understand why some spots become so bare while other areas stay nice and green. The problem with "burning" from over-fertilizing is not that there is no water in the soil, but that moisture is drawn out of the plant due to osmotic pressure. So if you can’t rule out a fertilizing mistake and the lawn doesn’t stay green in some spots despite regular watering, this could be the reason.
If you have been following the principle “a lawn needs water, water, water,” the grass will have shallow roots and therefore be vulnerable when water is temporarily lacking ;-) This applies to many plants, especially hedges (water heavily at the beginning, then reduce watering, no automatic irrigation!).
