Compost Calculator

Find the best mix of ingredients for great compost

All materials that you are likely to put into your compost pile have some nitrogen and some carbon in them. For your compost to heat up properly and produce high quality compost it must have the proper ratio of the two. For best results you want to have 25 to 35 units of carbon for every unit of nitrogen in your mix. The Compost Calculator allows you to determine what this ratio is, given your particular mix of materials.
