    • providing a comprehensive and confidential report with system evaluation data and analysis.
  • Seasonal irrigation and soil moisture monitoring, including
    • installing flow meters and data loggers at individual irrigation blocks, and
    • installing soil moisture sensors and data loggers to monitor moisture levels throughout the growing season.
  • Seasonal crop canopy monitoring
  • Irrigation system design consultation
  • Irrigation scheduling decision support
  • Connecting growers to network of agency resources, including the

Why improve irrigation management?

The benefits to improving irrigation management include:

  • Maintaining or improving consistencies in crop production and quality
  • Reducing costs with efficient use of water and nutrient inputs
  • Conserving water in our semi-arid climate that features cyclical periods of drought
  • Conserving fertilizer
  • Maintaining and improving groundwater and surface water quality
