| Sumario: | [EN] Flow distribution uniformity is a parameter used for micro-irrigation evaluation. Different methods describe how to collect data and to calculate the distribution uniformity, such as the procedures developed by Merriam and Keller (1978), ASAE (1998) and Burt (2004). The main difference between these methods is the number and location of the drip emitters used for calculating the distribution uniformity. Nowadays, with increasing use of precision technologies, an alternative method is proposed to estimate distribution uniformity in real time and without using the manpower required by this time-consuming task. This method consists in using flow and pressure data collected by the devices installed in the drip irrigation unit. The proposed procedure will also allow to evaluate subsurface drip irrigation systems, which distribution uniformity otherwise would be very difficult to determine frequently. The evolution of the results obtained by the proposed method according to the irrigation time is more similar with that obtained by Burt’s (2004) method than that obtained following Merriam and Keller’s (1978) method. |
