Performance and radial distribution profiles of a variable flow rate sprinkler developed for precision irrigation

Scientia Agricola, 2012
Variable rate sprinklers (VRS) have been developed to promote localized water application of irrigated areas. In Precision Irrigation, VRS permits better control of flow adjustment and, at the same time, provides satisfactory radial distribution profiles
