    #8043305 - 02/19/08 03:23 PM (15 years, 11 months ago)

Well now !

Starbucks reports that most of the acidity is removed in the brewing process, leaving used grounds with an average PH of 6.9 and a carbon-nitrogen ration of 20-1. Starbucks commissioned a study in 1995 conducted by the University Of Washington College Of Forest Resources to better understand the make up of organic matter in coffee grounds and found the following:

Primary Nutrients

Secondary Nutrients

* Nitrogen 1.45%
* Phosphorus ND ug/g
* Potassium 1204 ug/g Calcium 389 ug/g
* Magnesium 448 ug/g
* Sulfur high ug/g

Notes:

ND = indicates sample is below detection limit
ug/g = microgram / gram
