Soils at pre- and post-burial of controlled graves with pig cadavers at different states of decomposition were analyzed and correlated with several soil and site parameters. Twenty-four pig (Sus scrofa) cadavers of two average weights (29.7 and 63.8 kg) were buried at two depths (50 to 60 or 100 to 110 cm)in a Chipley soil (thermic, coated Aquic Quartzipsamment) and a Sparr soil (loamy, siliceous, subactive, hyperthermic Aquic Arenic Paleudult) in north-central Florida. The soils were sampled at 10-cm intervals before burial and the graves were excavated at the termination of each monitoring period to collect post-burial soil samples. The results indicated that regardless of the cadaver scenario there was a limited soil area (20-30 cm) near the pig remains that was affected by decomposition and diagenesis. The highest differences of extractable P, Ca, and Fe were in soils sampled directly under the cadavers. The soil data were then compared with the total decomposition score (TCS) to determine if statistical relationships exist. A highly significant, inverse correlation existed between P/Ca ratio and TCS (r=-0.752) and a positive relationship was noted between TCS and pH (r=0.689). In summary, the levels of extractables P, Fe, and Ca, and pH are directly related to the TCS and length of burial.
