  2. Distribution of Water Irrigation Design Design of Sprinklers/Nozzling Sprinkler control - control of speed of rotation and trajectory Zoning vs. Valve in head Fault detection and repair Sub-surface irrigation Effect of wind Water droplet size Grey & effluent water heads and valves Lower pressure loss sprinklers for pumping savings Fertigation/Chemigation Water as a vehicle to transport chemicals Core Product Investments Scheduling of Application Weather measurement Effective use of rainfall ET Soil moisture measurement Topography Control based upon soil moisture reading Effect of weather and incorporating forecast into irrigation plan Rain sensors Plant Materials Low water use plants Salt tolerant grasses I.e. Paspallum Transgenic plant materials Soils Distribution of soils Topography Type of soil Soil modification including drainage and SubAir Water retention Water Quality/Water Treatment Sulfur burners Magic filters Cow Magnets (magnet fields) Wetting agents Soil salinity monitoring Desalinization Consulting Helping people through water issues Commercial “NSN” Training and Education Site surveys Ag related services Other Installation equipment integration Dimensions of Water Planning

  3. Complex problem: where, when, how much ??? Agronomics of water use - • soil conditions • topography • weather • species • season Technologies - sensors • sensitivity • reliability • practicality • weather stations Data interpretation • diagnostic usefulness Logistics of data collection • practicality • GPS/GIS Data presentation/transfer – visual tools, irrigation control • usefulness

  4. Data Collection – System Performance

  5. TAO Resources

  6. What is a Water Management Plan? A Water Management Plan reviews current water management practices and identifies opportunities for improvement in water-use efficiency/conservation for the whole club facility • Setting a goal, planning process and water management approach • Site assessment/Data collection • Strategies for water use efficiency and water conservation • Implementation and review

  7. What is included in a BMP? • Assure Overall Quality of the Irrigation System • Design the Irrigation System for the Efficient and Uniform Distribution of Water • Install the Irrigation System to Meet the Design Criteria • Maintain the Irrigation System for Optimum Performance • Manage the Irrigation System to Respond to the Changing Requirement for Water in the Landscape

  8. BMP Templates http://www.commodities.caes.uga.edu/turfgrass/georgiaturf/Water/Articles/BMPs_Water_Cons_09.pdf

  9. Monitoring Performance Instructions: • Enter water meter reading using the totalizer meter on the pump station or a meter that measures total water leaving the pump station to be used on the golf course turf. • Enter the projected flow from the central computer for the same period. • Enter the calculated ET for the time period being used. • Make sure that the difference between the actual flow in the field and the project flow is within a reasonable tolerance and watch for sudden data spikes. • Based upon a crop coefficient of 0.8 the spreadsheet will calculate the over/under water use for your turf area • Use this as a tool to monitor water use.

  10. Monitoring Performance

  11. Monitoring Performance Data from soil moisture sensors Water applied in excess of “full point” is wasted through leaching beyond the root zone Full point (field capacity) Zone of optimum performance Refill point Moisture pool allowed to drop below “refill point” results in turf approaching wilt • Allow us to precisely measure soil moisture • Can calibrate sensors to “empty” and “full” • Sensors are the most precise method of measuring plant available moisture

  12. Next Steps?? • Is the collection of resources enough? • There are many more available out there than are currently on the NGCOA site • Do we want to create or recommend a best practice BMP? • BMP really only suggest a process. • Do we need to establish performance criteria? • Do we need to establish an expectation of continuous improvement?
