研究了堆肥过程中粪便氮的生物降解性。粪便氮被细分为两部分：一种原本不具有生物活性的氮（NXI），以及一种缓慢生物降解的氮（NXS）。在堆肥过程中，通过异养微生物的内源呼吸繁殖出惰性类型的有机物（NXIB）。粪便氮的评估得出的结论分别为 75% (NXS) 和 25% (NXI)。据估计，NXIB 可能是初始粪便氮的 9%。因此，大约 34% (NXI+NXIB) 的初始粪便氮作为生物惰性类型的有机氮保留在堆肥材料（锯末和粪便的混合物）中。
Biodegradability of fecal nitrogen was studied in composting process. Fecal nitrogen was subdivided into two fractions: a type originally inert in biological activity (NXI), and a slowly biodegradable one (NXS). During the composting process, an inert type of organic matter (NXIB) was reproduced by endogenous respiration of heterotrophic microorganism. Evaluations for fecal nitrogen formed a conclusion of 75% (NXS) and 25% (NXI), respectively. It was estimated that the NXIBcould be 9% of initial fecal nitrogen. Thus, approximately 34% (NXI+NXIB) of initial fecal nitrogen remained in the composting material (mixture of sawdust and feces) as biologically inert type of organic nitrogen.
