Poster Header - Assessing Soil Nitrate Sensing Protocols Based on Electrochemical.png

Objectives

  • Perform solute displacement experiments using soil columns packed with soils of different textures, analyzing changes in nitrate concentrations with electrochemical and optical nitrate sensors.
  • Utilize the program CXTFIT to compare and evaluate the sensors' experimental versus predicted breakthrough curves (BTCs).

Poster Header - Assessing the Effectiveness of Sunflower Production Conservation Practices in Reducing Nitrate Leaching to Groundwater

Objectives

  • This study assessed how conservation practices in sunflower cultivation affects nitrate leaching into groundwater. We employed a three-tiered approach:
  • Monitoring groundwater nitrate levels
  • Tracking nitrate movement through the vadose zone
  • Field scale mass balance

Objectives

  • Test three different regression strategies to examine the strength of the relationship between EMI sensor readings (ECa3, shallow and ECa5, deep reading) and predicted soil salinity (ECe, 0-120 cm):
    • Field Specific Regression (FSR)
    • Whole Farm Regression (WFR)
    • Analysis of Covariance (ANOCOVA)
  • Determine whether the examined approaches can be used to build a robust model for ECa calibration using minimal (6) ground-truthing locations.

Objectives

  • Determine whether satellite time series data can guide tall wheatgrass (TWG) harvest periods and identify declining yield due to salt accumulation in root zone
  • Assess the potential to use satellite imagery as a management tool for TWG production under saline-sodic irrigation
  • Provide a decision support tool to the SJRIP managers to improve the long-term sustainability of forage production in the reuse facility
