Carbon-rich or brown materials contribute to the lightness and fluffiness of the compost’s texture. But more than one composter has discovered, to his distress, that the grass he dumped into his compost pile, instead of decaying into a nice, dark, crumbly, humus-rich compost, has instead putrefied into a slimy, stinky mess.Grass does indeed make a fine feed-stock for compost, but it easily compacts into an oxygen-free mat.
