I live in western Nebraska in a house I bought at the wrap up of last summer. Both last year and this year I've have different lawn mower folk cut my grass, but this year, I've noticed my grass is turning brown contained by long parallel strips (a few inches wide by 5 to 8 feet long) going on for a foot apart.

Any idea what causes this? To my wisdom, no chemicals have been used on my pasture, and I've watered it as little or less than I did last year because we've have regular rain. Everyone else's lawns around me look about one and the same as last year.

Please keep contained by mind I don't know anything about lawns and any educated suggestions are constructive.

This almost sounds like the lawn be laid just prior to you purchasing the house and pieces of the sod is dying out due to lack of root contact near the soil. The way you can tell if the sod is to a certain extent new is you will see (for lack of a better bearing to explain) a brick pattern and gaps between the edges of the sod.

Then too it may be the prairie guys may be cutting the grass to short. Some grasses needs to be something like 3" or higher. If the lawn is shifting with small humps, the mower will cut short on the hump.

You might geet a professional lawn fertilizer company come look and offer you a free estimate and doing so mention the areas and they may just offer what is the effect then recomend what they can do to help.
