I think the Am fungi relationship as it pertains to P release is an important consideration for anyone interested in "true" organics. From what i can gather, w/ guano there appears to be more water soluble P ions available than many other organic sources. But, there is still a much higher percentage of the insolubles (relative to the soluble.) Which naturally points the true organic gardener in the direction of AM. Particularly myself since my source for guano is a spelunker and the guano comes to me as fresh manure !!
Obviously, the canna plant is not AM dependant. But, in my observations of the hemp weeds local to my region, there are definitely fungal associations going on at the root. In fact, this was my source for AM. I unearthed a dead hemp weed and cut up the roots (covered in the fungi) to introduce into my soil mix.
Since i have heard no mention so far of fresh guanos, my method is to make an "exotic" compost.
I want the bulk of this mix to be my guano so I sprinkle it w/ a little alfalfa, (probably about 1/10) add some finished compost from my pile (about 1/5) and I bed this on some straw (from a bale) This gets some water to about the "damp sponge" level. I turn it about 1x/week and let it run for ~2 months before I use it.
I screen off the remaining solids from the straw.
this guano is from insect eating bats and is high P w/ a little N. I figure it at about 3-6-1 once composted w/ my alfalfa addition.
