Soil Acidity

Soil acidity mapping highlights land where acidification due to normal farming practices is, or could become, a significant problem. Mapping shows surface and subsoil acidity, and surface buffering capacity (ability to withstand pH changes), while detailed proportion data are supplied for calculating respective areas of each soil acidity class (spatial data statistics).
