Garden with Insight v1.0 Help: double-digging

Double-digging is a method for deeply digging the soil used by many gardeners, where the soil is mixed and aerated down to a depth of several feet. The method usually implies digging a quantity of soil and setting it aside while aerating and sometimes adding an amendment to the subsoil below, then returning the top soil. There are several styles of double-digging advocated by different gardening books.

In this simulation double-digging is modeled very simply by mixing all the soil in the soil profile. This is not a realistic description of double-digging but it represents to some extent the depth of the mixing.
