c ) The following data was obtained with tension plate and pressure plate extraction devices. Plot the soil water retention curve (SWRC) on a semilog scale (logarithm of matric suction versus wetness) (2 marks)
a) Estimate the bulk density, assuming the soils do not swell or shrink (2 marks)
b) Estimate the volume and mass wetness at FC, PWP and calculate AWC (mm) per 1 m depth (6 marks)
