This note reports the effect of improved soil physical conditions, as characterized by oxygen diffusion rate (ODR), on the growth of oats ( Avena sativa L.) at the critical soil salinity level (EC e = 5.0 mmhos cm −1 ). In a coastal alluvial soil at critical salinity level (EC e = 5.0 mmhos cm −1 ), the yield of oats increased from 0.55 g/pot to 10.88 g/pot as ODR increased from 7.3 ✕ 10 −8 g cm − 2 min −1 to 31.0 ✕ 10 −8 g cm −2 min −1 . The root elongation of the plant also appeared to be related to ODR.
