Mar 21, 2016 · The type of soil a body is buried in can alter its rate of decomposition—acidic soil can cause a body to break down up to three times faster than alkaline soil. This is useful information for investigators to keep in mind when searching for a body, particularly if they are seeking a body that has been missing for several years.

- Stage 1 Fresh (1-2 days) This stage begins almost instantly from the moment of death. As the heart stops beating, the body’s cells gets deprived of oxygen and pH changes occurs.
- Stage 2 Bloated (2-6 days) This stage of decomposition includes the first visible signs of decay, namely the inflation of the abdomen due to a build-up of various gases produced by bacteria inside the body.
- Stage 3 Decay (5-11 days) The previously inflated carcass now deflates and internal gases are released. As the tissues break down the corpse will appear wet and strong odours are very noticeable.
- Stage 4 Post-Decay (10-24 days) By the time this stage is reached, decomposition slows, as most of the flesh has been stripped from the skeleton, though some may remain in denser areas such as the abdomen.
Nov 3, 2024 · One exotic way to preserve a dead body is tanning. This has been known to happen when the body is buried in a highly acidic, low-oxygen environment such as a peat bog, and the phenomenon is responsible for well-preserved but leathery bog bodies like the 2,300-year-old Tollund Man.
Sep 1, 2010 · If the corpse has been buried so that anaerobic (oxygen-free) conditions prevail, the body will be acidic (less than 7.0). The more extreme the pH, the quicker the decomposition.
Apr 5, 2013 · In this specific case, the two bodies had been buried 20 – 25 years ago in the same cemetery about 150 m. apart, but the one buried where the pine trees grew (acidic soil) were in very poor condition, and many of the smaller bones were not to be found, and the ones in the grassy part of the cemetery which had sandy soil were in remarkably good condition.
Remains buried below one meter are unlikely to be significantly affected by above ground temperature changes. Soil pH can also impact bone decomposition. A pH below 7 is regarded as acidic and anything higher is an alkaline, a pH of 7 is neutral. Acidic soil, particularly pH of 5 and lower is likely to increase the rate of
