Irrigation and Fertilizer Management

  • Fertilizer Management
  • Irrigation Maintenance

    FREP has published irrigation maintenance checklists for various systems. These checklists summarize important aspects of pressurized systems to maintain and inspect while they are operating. They can be a useful tool for growers and irrigators to print and reference when running irrigation sets so that they can best insure that the system is performing optimally.

  • Irrigation Scheduling Tools
    • CropManage (UC ANR)

      CropManage is a free online decision support tool for irrigation and nutrient management recommendations. See the CropManage brochure .

    • California Almond Sustainability Program’s (CASP) Irrigation Calculator

      Generates almond orchard irrigation run time schedules that advise the amount and timing of irrigations based on local evapotranspiration and information about your individual orchard and irrigation system.

    • Wateright (CSU Fresno CIT)

      A multi-function, educational resource for irrigation water management. Resources include water balance and agricultural scheduling.

    • CIMIS

      The California Irrigation Management Information System (CIMIS) was designed to assist irrigators in management and water use efficiency.

    • OpenET

      OpenET uses best available science to provide easily accessible satellite-based estimates of evapotranspiration (ET) for improved water management. Developed through a public-private partnership, the platform will make satellite-based data on evapotranspiration widely accessible to farmers, landowners, and water managers.
