That's what some folk are saying. For example:

Sprinkle used grounds around plants before rain or watering, for a slow-release nitrogen.

Or:

Coffee grounds have a carbon-to-nitrogen ratio of 20:1, roughly equivalent to that of grass clippings. After brewing, coffee grounds contain up to 2% nitrogen. For composting purposes, consider coffee grounds "green" material similar to grass clippings.

Google around for pages mentioning coffee grounds and fertilizer or coffee grounds and nitrogen. I don't know if coffee grounds are exactly a great fertilizer, but apparently they're not bad, except, according to at least a couple of pages I saw, that they're also acidic.

Thanks Eeksypeeksy,
I did what you suggested and Googled for coffee grounds and nitrogen, came up with a bunch of sites, that definitely do recommend it as a good way to use around your plants and trees, also good to keep ants away it says.
Thanks for the advice.
