Example 3
Figure 12 illustrates the movement of salts at the bottom of the wetting front in drip irrigation in IrriMAX
®
6.
Soil moisture data showed that the bottom of the wetting front just reached to a depth of 50 cm with each
irrigation
With successive irrigations, estimated EC increased from 1162µS/cm on 20 November, to 1233µS/cm on 22
November and 1287µS/cm on 23 November at this depth.
Rainfall of 22mm on 23 November caused movement of the wetting front from the overlying layers, which
diluted the solute concentration.
