As you can see in my other posts our soils is built up on fill (it wasn't me.. concrete rubble, asphalt, old bricks). Most of it is tons of woodchips, compost spent potting mix. So I have a LOT of organic matter but no clay and very little sand. I did a jar test and it confirms my suspicion. I think I need to get two things:
1. rock dust (the only thing I came up with so far is crusher dust from the nearest basalt quarry which is not really dust, the particles are mostly bigger)
2. some clay - bentonite?? Something powdered is easy to work with. What other clays are there and is there an advantage of one over the ther?
What do you think? Which type of clay? Application rate? I'm in NSW Australia.
I am reading " the enlivened rock powders" very Steinery and not very practical for me.
