Abstract
The effect of replacing furrow irrigation with subsurface trickle irrigation on some soil physical and chemical properties of hardsetting red Alfisols when sown to cotton were evaluated on two farms (Bellevue and Brae Park) in the Macquarie valley of New South Wales, Australia, during 1998 and 1999. The soil at Bellevue had a heavier soil texture than that at Brae Park. Soil was sampled from depths of 0–0.15 m, 0.15–0.30 m, 0.30–0.45 m and 0.45–0.60 m in "paired" fields sown to either trickle- or furrow-irrigated cotton. The soil properties evaluated were soil structural stability as dispersion index, hardsetting characteristics, salinity as electrical conductivity (EC) of a 1:5 soil:water suspension, and sodicity as EC/exchangeable Na ratio.
