A decomposing human body in the earth will eventually release approximately 32 g (1.1 oz) of nitrogen, 10 g (0.35 oz) of phosphorus, 4 g (0.14 oz) of potassium, and 1 g (0.035 oz) of magnesium for every kilogram of dry body mass, making changes in the chemistry of the soil around it that may persist for years.

The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body.

The time for an embalmed body to be reduced to a skeleton varies greatly. Even when a body is decomposed, embalming treatment can still be achieved (the arterial system decays more slowly) but would not restore a natural appearance without extensive reconstruction and cosmetic work, and is largely used to control the foul odors due to ...

After 13 hours, muscle and rectal temperatures in pigs are better estimates of time since death. [31] In dogs: what changes and when. Eye K+ decreases from 1.5 hours after death to 7 hours after death. [32] Rigor mortis of hindlimbs persists up to 24 hours. [33] Elbow rigidity is lost after 3 to 7 days. [34]
The microbial timeline of how a body decays is known as the microbial clock. It estimates how long a body has been in a certain place based on microbes present or missing. [22] The succession of bacterial species populating the body after a period of four days is an indicator of minimum time since death. [23]
A family in Florida is demanding answers after they said their loved one's decomposed body was found in the closet of a nursing home more than a week after he was reported missing.
The breakdown of the proteins of a decomposing body is a spontaneous process. Protein hydrolysis is accelerated as the anaerobic bacteria of the digestive tract consume, digest, and excrete the cellular proteins of the body.
