Can temperature affect the release of ninhydrin-reactive nitrogen in gravesoil following the burial of a mammalian (Rattus rattus) cadaver?
Although temperature and soil type are well known to influence the decomposition of organic resources, the effect of these variables on the release of ninhydrin-reactive nitrogen (NRN) of cadavers in soil has received little experimental investigation. To address this gap in knowledge, juvenile rat...
