The objective of this study was to simulate soil water contents at different irrigation levels and soil water retention barriers (SWRB) depths in sandy soil. Soil water simulation models were created by means of the HYDRUS-2D program using soil and weather parameters. This study was conducted under field conditions in 2010 and 2011.
Soil water content was measured by frequency domain reflectometry (FDR) sensors. Treatments included three irrigation levels, 33%, 66%, 100% of available water-holding capacity (AWC), and two different SWRB depths (30 cm and 40 cm). Perennial ryegrass was sown in each treatment. Correlation coefficients between actual and simulated soil water content via HYDRUS-2D models were between 0.74-0.94. These results indicate that the HYDRUS-2D model can be used to determine soil water content for sandy soil.
