Build a compost pile that heats up and breaks down fast by hitting the right carbon to nitrogen balance. Enter the weight of your carbon rich browns such as dry leaves, straw or cardboard and the weight of your nitrogen rich greens such as grass clippings, food scraps or manure, along with the typical C:N ratio of each. The calculator blends them by their nitrogen content to return the combined ratio of the whole pile. Microbes work best near thirty parts carbon to one part nitrogen, so the tool tells you whether to add more browns or more greens to reach that sweet spot. Too much carbon stalls the pile and too much nitrogen makes it smell. Everything is calculated instantly in your browser with no signup.
