that's just guano, I think most of us organic growers have used it at some time. It works just like most amendments, but like cannakis said it's not exactly environment-friendly. For guano I prefer seabird guano, it's like 12-8-2, but honestly if you add shit to your soil, add rabbit or alpaca manure instead.

I always wonder how they have organic seabird guano, do they confine the birds, feed them only organic and collect the poop?
My suggestion would be to thermal and vermicompost any mammalian manures.
I echo everyone else on bat guano harvesting practices. Not a deal breaker, but I don't use any bat guanos in my mixes (like grease said I have though).
Peace!

i actually haven't had any problems with the rabbit or alpaca manure un composted, and my strains are kinda light feeders, i whole-heartedly agree on any other manures, wait, i have heard that deer manure can be used too, haven't done that though.
an old grower once told me," if the poo is in pebble shape, you are probably ok to use it"
Course i am trying a new method of making a alpaca/rabbit manure rich vermicompost, i wonder how much of the NPK i lose when the worms eat it? Anyone have an idea?

Thermal and vermi composting are going to kill any unwanted pathogens. You could do one or the other, but as I read more about composting, I'm going to be putting my inputs through both.
Do not worry about NPK. Although we learned a lot from Albrect, his ratios don't necessarily pertain to organic growing. The plant just needs the nutrients to be available, and it will take what it wants. I started to comprehend this when I found an Iowa State University documenting of the highest and lowest corn producing soils in Iowa over a ten year period. The Phosphorus numbers were all over the board. Absolutely no correlation between highest yield and phosphorus... But wait, don't we need high P levels for flowering? That's what it says on the hydrostore bottles!
More hydrostore myth...

honestly its not the phosphorus i was concerned with, more of the nitrogen, the strains i have stretch usually 300 percent during flowering (i like me my sativas)
Interesting about that study though, I've done a bunch of experiments with all kinds of plants, and from what I've seen its the micros and nitrogen that makes the primary differences in visible plant health, now of course plants need ALL types of food, that goes without being said, but nitrogen and micro issues seem to pretty much STOP growth, almost to a stand still.
I shamefully admit I've tortured MANY plants, cannabis and otherwise, just to see what happens when this or that is neglected, etc, etc. I learned way more about plants doing that, than successful harvests, success doesn't teach you much, to be honest. Kinda how like doctors take apart cadavers first, i suppose.

Nitrogen is easy to add imo, and is in many of the amendments. Take a look at neem meal and crab meal, often overlooked sources. Plus EWC, organic matter, etc; N has never been a problem for me. Keep in mind other things can appear as lack of N, but may not actually be the case.
Peace!
