Integration of Hydrogeophysical Datasets for Improved Water Resource Management in Irrigated Systems
  • Presentation Type: Thesis Defense
  • Date: 1/7/2017
  • Abstract:

    Water scarcity is predicted to be the major limitation to increasing agronomic outputs to meet future food and fiber demands. With the agricultural sector accounting for 80-90% of all consumptive water use and an average water use efficiency (WUE) of less than 45%, major advances must be made in irrigation water management. Precision agriculture offers the technologies to address and manage for infield variability and incorporate that variability into management decisions. The major limitation to implementing this technology often lies in the management of spatial datasets and the writing of irrigation prescription maps that address variables impacting crop yield and soil moisture. While certain datasets and mapping technologies exist in practice, here I explored the utility of the recently developed cosmic-ray neutron probe (CRNP) which measures soil water content (SWC). The key advantages of CRNPs are the sensor is passive, non-invasive, mobile and soil temperature invariant making data collection more compatible with existing farm operations and extending the mapping period. The objectives of this study were to investigate strategies to: 1) improve the delineation of management zones within a field and 2) estimate spatial soil hydraulic properties (field capacity and wilting point) to make effective irrigation prescriptions. To accomplish this, a series of CRNP SWC surveys were collected in a 53-ha field near Sutherland, Nebraska. The SWC surveys were analyzed using Empirical Orthogonal Functions (EOF) to isolate the underlying spatial structure. I found that measured SWC at field capacity and wilting point were better correlated to CRNP SWC EOF as compared to other commonly used datasets. Based on this work I proposed a sampling strategy for better qualifying soil hydraulic properties. While the proposed strategy will increase overall effort as compared to traditional techniques, rising scrutiny for agricultural water-use may make this technology cost effective.
