The trench method

One thing I'm loving about the trench method ... there's so much clay in my top soil that the heat is forming a crude Terracotta (see the orange in my pic).   I've already tested that orange stuff;  it is stable in water and holds its shape as a loose gravel which helps the porosity in my dense clay topsoil.   I had been hauling in play sand to amend my potting soil.  No need for that anymore, YAY!

Totally agree. I first saw a big improvement after burning in a trench. Huge difference in the heavy clay.

I would be careful about mixing sand with clay. Many people here have found that sand mixed with heavy clay results in a cement-like texture.  Not exactly ideal for root or plant growth, nor for infiltration of rain water.

Making biochar with the trench method would be a much better solution IMHO.  Biochar drains well and retains moisture.

I also think that the trench method works well for someone with acreage and a lot of large wood to burn.  You have to have enough space to dig a trench.   I can't use it because I live in the suburbs. People have already called the fire department on me twice.  I use a TLUD with a chimney because I can put it in my driveway and get it done there. Then I can crush it when I drive over it in burlap bags.  Everyone has to find a method that will work with their space and available materials.

Fortunately I live in an area that doesn't strongly restrict burning, though it is suburban.
I dig trenches every fall to bury all the leaves and sticks that fall. Usually don't bother burning but it really did seem to make a difference.
The last few years I have been putting logs in the bottom of the trenches. That also seems to really help later soil texture when I dig that area up again a year or two later and mix all the rotted wood and leaves in with the soil. It also get all the kitchen garbage and ash and charcoal from the fireplace.
