It's hard to say from just a picture. You'll definitely want to sift out all of those twigs and wood like you said. Once that is done it should feel like sandy dirt and it should have no foul smell when wet for long periods of time.is this soil fully mineralized?
I did the soak/dry process 3 times. should i do it another time?
this is a really close shot of the dirt, im going to try to find a really fine sieve to get the remaining little bits of twigs and wood.
