This paper is about incineration of sewage sludge. They consider incineration at temperatures like 700C to 900C. Seems like you end up burning 98% of the nitrogen, which is then released as gas (bottom of page 12, just before Conclusions). The output ash only contains 2% if the input nitrogen.
Kind of defeats to point of using the output as fertilizer.
