Subsurface Soil Acidity (ASRIS)

Soils are classified according to the pH of the subsurface layer. Subsurface soil refers to the layer immediately below the surface, and typically has a depth range of 10-20 through to 10-30 cm. The a

Surface Soil Acidity (ASRIS)

Soils are classified according to the pH of the surface layer, according to the lower pH values recorded among similar soils, i.e. it is assumed that each soil class has a characteristic level of acid
