I'm seeing some phosphorous deficiencies in my soil, and I'm wondering what's the organic approach to fixing this? I know I can water in or top dress some amendments, but it would take a long time before that material is broken down & available.
I've thought about making an AACT with some high phosphorous bat guano in there, but I've mainly used AACT to boost the microbial life in my soil & not to feed my plant nutrients.
Top dress and use that AACT with bat guano will help. Check out mr. Canuck grows on yt he does that to fix the deficiencies. Hes grows with organic dry amendment only.
