Özet

Decomposition, a postmortem process including autolysis and putrefaction, is affected by many factors (e.g., humidity, microbial activity, soil properties). The purpose of this study was to determine the importance of soil type in decomposition process. Changes occurred in two intervals (3 and 6 months) were evaluated using a total of 32 Sus scrofa limbs by burying in four different types of soil (loamy, clayey, sandy and organic). The extremities in all soils had lost weight over time; however, mass loss was greater in loamy and organic soils in both intervals. Entomological findings were also assessed. Obtained findings of soil analysis and evaluation of decomposition were compatible. In conclusion, the present study revealed that soil properties and textures should be taken into account in evaluation of decomposition and estimating postmortem interval in crime scene investigation.
