Raised Bed Soil Calculator

Enter your bed dimensions and how many you are filling. The calculator uses the reliable 60/30/10 recipe: 60 percent topsoil, 30 percent compost, 10 percent aeration material (perlite, coarse bark fines, or rice hulls). For deep beds, you can cheaply fill the bottom third with logs and coarse organic matter.

Bulk topsoil and compost quantities beyond a yard or two are cheaper delivered; the topsoil calculator covers weights, and local suppliers are in the directory.
