Agriculture is a large part of what makes San Diego County unique and the Rainbow Creek watershed is no exception.  Agriculture (consisting of commercial nurseries, agricultural fields and orchards) have been indentified in the TMDL as one of the sources of high nitrogen and phosphorus levels in Rainbow Creek.

By responsibly using fertilizers and pesticides, agricultural operations will reduce their impact on Rainbow Creek.  Eliminating any runoff of irrigation water will also reduce the impact of nitrogen and phosphorus on Rainbow Creek.

The brochure "Micro-Irrigation Tips for San Diego County Orchards" is a great way to learn about practical (and easy) ways to increase your grove's irrigation system's efficiency (please click HERE to download).  In "Practical Irrigation Scheduling" you'll learn about how to set up your irrigation schedule to maximize the benefit for your groves or orchards (please click HERE to download).

If you are interested in learning more about your irrigation system, Mission RCD's Mobile Ag Lab will come out (for FREE!) and conduct an Irrigation System Evaluation for our grove, nursery or orchard*.  Just call our office at (760) 728-1332 if you would like to set up an appointment to find out what your irrigation system's emission uniformity is and how to increase it (and save you water and money!) if it is low.  The Mobile Ag Lab will also generate a water schedule for your specific grove.

More information on Best Management Practices (BMPs) for agricultural operations can be found in the Rainbow Creek Nutrient Reduction Plan.

*The grove or nursery must be at least 2 acres of planted trees or potted plant material and must be located within Mission RCD's district boundaries.
