So I am starting my swale ditches / hugelkultur beds/ terrace project. I have a steep bank in front of my house that is 250 feet long 20 to 30 feet tall. The soil at the top that I will be terracing is 18-24 inches deep sandy loam little high in acid low in nitrogen, the rest is decomposed granite.
So here is the dilemma, I use the granite for construction hauling out 80 yds tomorrow and back hauling black sticky clay. So I need to start digging. Its a big project and I don't want to mess it up.
The materials I have or have access to.
Top layer sandy loam low N high acid
Black sticky clay high N holds water almost like Bendite
Base decomposed granite leaches water
Unlimited bull pine live and rotted
Madrone live and dead and rotting
Fresh wood chips
Old decomposed wood chips (looks like soil)
Haven't found compost yet
The equipment is on site and it looks like my terraces / swale ditches will be eight feet high and seven to eight feet wide on contour.
I don't want to get It wrong so I am looking for help on getting the rite combination. Any help would be great.
