Grass circles?

We have a strange thing going on here at CBC, grass circles, or at least partial circles. They are strips of grass much greener and taller than the surrounding area formed in a perfect arc about 10'-15' across. One I have noticed that was not there last year is a double, almost like a golden arches in design. Anyone have any idea what is causing these?

animal piss! Animal urine has amonia in it (especially dogs) and amonia is a fertilizer. The only way to nuetralize the amonis in urine is with tomatoe juice. You would have to convience the homeowner to mix v-8 in there food. Plus its good for dogs....Nathan

Yea, that's it....a 10 to 15 ft. circle would have to be a big dog! lol I think Nathan overlooked the 10-15 ft. thing, was referring to the pet spots that are so commonly found -especially at this time of year just off the porch steps due to he winter snow and cold keeping the pets from wandering far. Incidentally, there is a product that is now available over the counter that are cookies that do this, as well. the dogs love them.
But anyway, Dave.... do a search on fairy ring, and it will give you all the info you need. It is due to organic matter below the surface caused by a tree that used to be there. As this material decays, it releases nitrogen that causes this condition. One thing you will notice with fairy ring, is that it is never a fully closed loop. There is always an opening making a "C" pattern.

Might also be the inexperienced fertilizer applicator fungus, caused when operator stops, then starts back up without shutting the fertilizer gate on his spreader!

yep .. fairy ring .. they can live like 80 years old. pretty cool ..

when u think about what it and fungus in general do, they break down organic matter so plants can utilize it.

so they are really good. if we could just get a fungus of that nature evenly spread on lawns they would be super green and healthy the ALL natural way.

the problem is getting it growing everywhere, evenly.
someone develops a fungus we can spread that will take hold evenly, they will make a FORTUNE. say goodby to areation,dethatching(it would decompose all the thatch),fertilizer.

i actually dont think anyone has tried lol
