摘要
•We applied a synthetic material around subsurface irrigation drip lines (GDI).•Root growth reduced matric head (Ψ) variability of tensiometers in the GDI.•Ψ variability of GDI tensiometers was lower than that of soil tensiometers.•Measuring Ψ in the GDI reduced number of tensiometers required in the plot.
