Contents: Soil Phosphorus
Description: This is one of the studies conducted to assess soil fertility in the Tonto Basin. Both agricultural and control samples were obtained to identify potential soil fertility deficiencies. Phosphorus is particularly useful for interpreting cultural sediments since it is one of the plant micronutrients added to the soil as a result of biological processes and chemical weathering.
