We have been using our llama poo for many years. We use it directly to the soils and as a topping mulch. Sometimes I use peat moss over the llama "beans" if it near the house and there is a strong odor.
I use some in the compost pile as a "green", we have lots of hay for the
carbon and need "green" for the compost. You'll lose some of the nutrients during the composting if you have "pile" composting like us.
The fresh beans that are saturated with urine make an excellent "tea" for watering.
Sometimes the "beans" will take a few years to completely break down, but they will. You can soak them in a five gallon
bucket for a week or so and they'll break down faster. Our
chickens scratch the pile and turn them, so most of the material is on it's way to breakdown.
It is the "best". Although I have seen the vegetation at the poo piles get damaged (for a short period), I have never "burnt" anything in the garden with the usage of beans. We have four "rescue" llamas and would use the poo from many more if I had access to it.
I would use the old bat guano and peatmoss - it never goes bad (the peat bogs are real old and when you "mine" guano you take the new stuff and the material that is many years old), it just changes it's moisture content. Sometimes the stuff gets real hard and you need to add moisture to it to break it easily.
