2014 Published by Elsevier Inc. All rights reserved. New irrigation strategies for limited water resources, such as site-specific variable rate irrigation, are required to maintain modern irrigated agricultural cropping systems. Recently, moving sprinkler systems have been modified for spatially variable water and chemical applications. Onboard sensor packages, such as infrared thermometers and spectral reflectance sensors, have been installed to provide near real-time field maps of water status, vegetation, and nutrient indices. Linking information on spatial and temporal development of abiotic and biotic stresses with instructions for site-specific sprinkler irrigation systems allows producers to maximize irrigation water use efficiency, improve sustainability, and diminish negative effects on the environment.
