Phosphate analysis and phosphate mapping

Phosphate analysis of soil is a common soil chemistry method in archaeology used to identify sites displaying traces of human activity.

The element under scrutiny is phosphorus (P), which has bonded to the soil in the form of organic and inorganic phosphates. These phosphates are naturally distributed throughout the environment unless influenced by external factors. Phosphates tend to be relatively stable in soil and can thus accumulate due to human activities such as waste disposal or burials. By extracting these phosphates from the soil, it becomes possible to identify areas with elevated phosphate levels.

When collecting samples for phosphate analysis, it is advisable to use approximately 1-1.5 deciliters as a suitable sample quantity. Use clean tools and store the samples directly in plastic bags before sending them to us.
