A Variable Rate Drip Irrigation Prototype for Precision Irrigation [PDF]
Agronomy, 2021 A new Variable Rate Drip Irrigation (VRDI) emitter that monitors individual water drops was designed, built, and tested. This new emitter controllers water application directly by monitoring the volume applied in contrast to uniform drip irrigation ...

Agricultural Management Options for Climate Variability and Change: Variable-Rate Irrigation
EDIS, 2012 Most fields are not uniform because of natural variations in soil type or topography. When water is applied uniformly to a field, some areas of the field may be overwatered while other areas may remain too dry.
