Predicting total soil lead from an acetic acid‐sodium acetate buffered solution

Abstract

Total soil lead was predicted satisfactorily from the Lead extracted by the Standard Morgan soil testing solution (sodium acetate with acetic acid, pH 4.8). Using 161 soils, 85% of the variance in total lead content was accounted for by:

Total Lead = ‐115 + 106.4 √Sodium Acetate Extracted Lead A modified Morgan solution, utilizing EDTA as a chelating agent, extracted greater than 3 times as much lead as the regular Morgan's solution, but was no better in predicting total lead.
