I've been messing around with burying my un-composted food waste beneath my lawn, but on contour--a kind of slow swale. So every time my compost fills up I'll combine it with mail shreddings 1 to 1, run outside, gently pull back a 6-8" deep by 3' section of sod on contour, bury the compost along the section, then replace the sod and squish it down a bit until it is relatively unnoticeable. The effect is like that of a minor swale, particularly as the length of the compost across the contour increases over time. At first it looks like your lawn is bloated, but later it shrinks as it slowly releases nutrients down the landscape. I think pulling the sod back downhill is preferable, as the opening/ridge created is infiltrating the water, not merely directing it slightly upwards over the surface. Not only does this improve your water situation and soil OM, but also saves you from having to compost if you don't like the whole pile/turn chore. It is a bit of task to dig (and kind of evokes embarrassment if you live in an HOA suburb with nosy people breathing down your neck at everything you do), but I really like the idea and I'm going to keep trying to make it easier and less noticeable. Has anyone else tried something like this?
