Spatiotemporal Analysis Of Variability In Soil Volumetric Water Content And Spatial Statistical Methods For Management Zone Delineation For Variable Rate Irrigation, Isak Lars Larsen
Theses and Dissertations
Irrigated agriculture is the largest user of freshwater in a world experiencing increased water scarcity and water demands. Variable rate irrigation (VRI) aims to use water efficiently in crop production, resulting in good yields and water conservation. With VRI, the grower is able to employ custom irrigation rates for different parts of a field. Adoption of VRI has been limited due to the complexity of matching irrigation to spatiotemporal crop water needs and the cost/benefit economics of VRI equipment. The goal of this study was to quantify spatiotemporal variability of VWC in a field that has uniform soil type and …
