Abstract:
A previously verified computer simulation model was used with properties of a regic sand as input data. Continuous and pulsed drip irrigation at rates of 1,5 l, 3 l and 9 l/h were compared with respect to vertical and horizontal soil water distribution. Results indicate that 3 l/h pulsed drip irrigation can successfully replace 1,5 l/h continuously applied, allowing a larger emitter orifice and reduced blocking problems, but still maintaining sufficient water above 0,6 m soil depth. At 9 l/h the differences between pulsed and continuous treatments were small.
