As part of the 13 Skills challenge, I am going to put in a hugelkultur (or woody bed). I have listened to a lot of podcasts about them from both TSP and Paul Wheaton, but it's not clear to me whether they should be aligned north/south, on contour, or along contour?
I am envisaging two of them, perhaps 12' long and 3-4' high, so this is not a Sepp Holzer 1000 yard long affair.
Our land is more or less flat pasture, with a very slight slope (maybe 1:300 or less) running downhill from north to south.
I am in the southern hemisphere, so things are north facing to catch the sun, rather than south facing as in the northern hemisphere.
