Variable Rate Irrigation of Maize and Soybean in West-Central Nebraska Under Full and Deficit Irrigation [PDF]
Frontiers in Big Data, 2019 Variable rate irrigation (VRI) may improve center pivot irrigation management, including deficit irrigation. A remote-sensing-based evapotranspiration model was implemented with Landsat imagery to manage irrigations for a VRI equipped center pivot irrigated field located in West-Central Nebraska planted to maize in 2017 and soybean in 2018.

Spatial irrigation scheduling for variable rate irrigation
Proceedings of the New Zealand Grassland Association, 2010 Recent unprecedented demands on freshwater for irrigation have led to over-allocations and restrictions. Variable rate irrigation (VRI) aims to optimise scheduling according to soil differences using irrigation prescription maps coupled with software-driven variable rate irrigators and individual sprinkler control for site specific management.
