Soil moisture tension (cb) before and after fill treatments at two depths below fill [15 and 45 cm (6 and 18 in.)]. Measurements were taken for 11 days before fill installation (pre), 14 days after fill (post 1, weeks 1 and 2), and another 14 days after fill (post 2, weeks 1 and 2). Tensiometers were placed next to ODR electrodes.
