Hydraulic conductivity variation in chilean volcanic soils due to wheeling and management

To describe the effect of wheeling on saturated hydraulic conductivity (ks), undisturbed soil samples from an Andisol were collected at three depths In Chilean soil classification system Andisols are defined as Malihue at the 2 sites minor and mayor mechanical stresses were applied repeatedly and th...
