The stuff that comes out of olive mills after the oil has been extracted is difficult to deal with. It ought to be a good addition to soils, increasing organic matter and other good qualities. But because it is a rather slimy sludge, it doesn’t decompose well. It is often composed by mixing half and half with sheep litter, and in a recent experiment, grape stems were added too. The result was faster, better compost. Olio, pecorino e grappa. Good for you, good for the land.
