Great form of urine available already packaged and processed by bats. comes recommended by Soma. I use a mix of Indonesian and Jamaican, Peruvian, and Mexican guano's at different phases of growth.

First, due to the large number of companies dealing in guano at the retail level, and the nearly infinite N-P-K combinations that result from that, it was necessary to select one brand to use for illustration purposes. I chose Sunleaves, because they are the most readily available in my part of the world. Sunleaves is OMRI certified, so you can be sure of it's 100% organic content. However, this should not be taken as an endorsement of this brand over any other, it was simply convenience.
Indonesian Bat
.5-12-.2
Jamaican Bat
1-10-.2
Mexican Bat
10-2-1
Peruvian Seabird
10-10-2
So the immediate question is how do we get such wide swings in the N-P-K values. The answer is quite simple actually. Diet. Bats that consume a diet high in fruit, like the Indonesian or Jamaican, excrete a guano high in P. Bats that survive on a diet consisting primarily of insects, like the Mexican, excrete guano high in N. Seabird guano doesn't have a single species source, many different birds contribute to these deposits, and the differences in the diets, and the diet of what the bird's food source was consuming, are reflected in a guano high in both N and P with a good amount of K as well. I want to reiterate that there a numerous companies out there, and their N-P-K values are different, in many cases, very different, and that difference opens all manner of numerical possibilities and this whole thing is numbers.
