I love coffee grounds for my compost and wormbins, but just this weekend learned that others will use them right on their soil.
What are some stories about that? Does anyone know what the nutritional benefits are, how much it could alter the pH?
I regret to say I know nothing more than it super-activates worms and cuts down remarkably any worm bin 'funkiness'. For those reasons alone I'm a big fan.
What else?

Very high N.
You can put it right on your soil, but make sure it is not right next to your plants because it can burn them.
Further, it is better spread out a bit rather than in gobs. Gobs make for spots that are too hot and can hurt the roots under the soil.
I generally avoid using decaf coffee grounds. Most decaf has been processed with some nasty chemicals for which there is a residue.

I'm in the process of trying to recover my lawn right now, after years of pesticides and inproper fertilizing due to believing the labels on those products. I'm not sure how coffee will work, but I am saving my coffee grounds and trying to use them in my yard. I've heard it's very good for breaking up clay (of which I have a lot) and can be especially good for roses.
I have recently spread some directly on my lawn and am in the process of reseeding spots, so I'm mixing some coffee grounds in with some soil and grass seed to make the patch.
We'll see. At the least the worms will get a buz. Who knows they might set up little cafes in the lawn.
btw - You can go into any Starbucks and pick up bags of used coffee grounds. They usually have them packaged and ready to go. If not, you can just ask. The last time I did, I walked out with a 20lb bag.

Lol. I'm laughing at the mental image you just gave me of worms sitting around in little berets, sipping a cup of Joe. And then getting wildly strung out after they've drunk 30 of them.
That's such a great tip that you can get used grounds from Starbucks. What a great, cheap way to recycle their stuff and get it on your lawn.
I have heard that coffee grounds are a bit weak as organic fertilizers go, so as such you need to use a lot of it. Like a cubic yard per 1000 sq feet. Which would be like 1/3 of an inch of coffee spread all over your lawn. At those concentrations, I wonder if you'd actually be able to smell the coffee aroma when you were outside. 
Chris, I think it takes like three weeks for the coffee to have an impact? Check back in and let us know how it's going!
