to define sampling zones to assess lime requirement, or for modeling changes in soil pH
when acid‐forming fertilizers or manures are added to a field. Our objective was to develop
a procedure to map this soil property. One‐hundred‐thirty‐six soil samples (0‐to 15‐cm
depth) from three Georgia Coastal Plain fields were titrated with calcium hydroxide to
characterize differences in pH buffering capacity of the soils. Since the relationship between …
