That's what some folk are saying. For example:nancyv. wrote:Hi STHLMgreen, are you serious or are you joking with me, to tell you the truth, I really didn't know coffee grounds are nitrogen...
Or:Sprinkle used grounds around plants before rain or watering, for a slow-release nitrogen.
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.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.
