| This course is designed to instruct the student on why proper irrigation scheduling is important and how an efficient schedule may be created using formulas that are available in the industry today. |
| |
| Scientists with the Texas Agricultural Experiment Station estimate that water used for irrigating landscapes could be reduced 25 to 30 percent by applying present technology and information. No matter how well the design or installation of an irrigation system, it will waste water if not scheduled and run properly. |
| |
| The course will cover topics such as: |
Hydrozones
Evapotranspiration Rates
Precipitation Rates
System Efficiency
|
Soil Infiltration Rates
Soil Moisture Holding Capacity
Allowable Depletion
Plant Factors or Landscape Coefficients
|
|
| Students do not need any prior skills on proper irrigation scheduling before they begin the class. Each student will learn the necessary techniques to create an efficient irrigation schedule. Students will learn basic plant, soil and water relationships as well as the formulas required to create an efficient irrigation schedule. |
| |
| Additional materials required to take this course include a pencil, paper, and a calculator. |
| |
| Upon completion of the course, the student will have a good working knowledge of the correct methods required to create an efficient irrigation schedule. The student will understand what the term evapotranspiration means and how it is adjusted for irrigation purposes by the plant factor or landscape coefficient. They will know how to calculate a precipitation rate and will understand system efficiency and distribution uniformity. The student will understand the difference in soil types, and how soil type and slope affect the infiltration rate and soil moisture holding capacity. They will have a good understanding of how water molecules are held in the soil and what the difference is between saturation and the permanent wilting point. Finally, the student will be able to gather all of these factors and calculate an efficient irrigation schedule using the formulas provided in the course to determine (a) how many days between irrigations, (b) the number of cycles per day, and (c) the minutes run time per cycle. |
