Potential Irrigation Reductions From Increasing Precipitation Utilization With Variable Rate Irrigation

2015 ASABE / IA Irrigation Symposium: Emerging Technologies for Sustainable Irrigation - A Tribute to the Career of Terry Howell, Sr. Conference Proceedings, 2015
Abstract. Much of the previous research quantifying the potential benefits of variable rate irrigation (VRI) consists of case studies with simulations using data from small numbers of intensely sampled fields. In this study, an indicator of the amount of root zone available water capacity that is unutilized by uniform rate irrigation was calculated for

Water and energy savings using variable rate sprinkler irrigation on a large maize farm in northern Italy

Agricultural Water Management
Maize is a key crop both globally and in Italy. In the Po Valley, it is cultivated on 500,000 ha, primarily for use in livestock production. Here, maize cultivation is highly dependent on irrigation, traditionally performed using border irrigation ...

Precision Turfgrass Irrigation: Capturing Spatial Soil Moisture Patterns with ECa and Drone Data

Agronomy
Turfgrass irrigation consumes a large amount of the scarce freshwater in arid/semi-arid regions. Approximately 50% of this irrigation water is wasted.

A novel variable-rate drip irrigation system to improve water use of vegetable crops in semiarid conditions

Agricultural Water Management
Irrigation system design and management focus on achieving the highest uniformity across plots. However, plots are not homogeneous and therefore require different irrigation depths in different areas.
