Fig. 6. (a) Volumetric water retained by two morphologies of petrocalcic horizon at field capacity (
FC) and two wilting points (
1.5 MPa and
4.0 MPa) and (b) available water holding capacity (AWHC) based on
1.5 MPa and
4.0 MPa. Fisher's protected LSD (
= 0.05) within measurement by letters, error bars represent sample standard deviations.
