Lesson: Irrigation basics and considerations for Lavender - John Steuble CID, CLIA

Irrigation basics and considerations for Lavender are as follows: Site information; Water source; Application equipment selection; Filtration equipment selection; Controls and Infrastructure,. invite you to consult the documentation. | Irrigation Basics & Considerations for Lavender Presented by John Steuble CID, CLIA Where To Begin • Site Information • Water Source • Application Equipment Selection • Filtration Equipment Selection • Controls and Infrastructure Site Information Gathering all site information is critical for an accurate and efficient system. • Accurately Measured Field or a Plot Plan of the property. • Include buildings, fences, sheds, roads, ditches, or any other obstructions that may affect your project. • Identify different Micro Climates of the areas. • Micro climates are areas in the project that are effected by sun, shade, wind directions, elevations and other natural elements. • Any Elevation Changes in the project. • Elevations differences will affect pressure losses and gains, irrigation runoff, runtimes, and may determine controller options. Site Information • Identify the Soil Type • Soil is made up of sand, silt and clay particles • The percentage particles is what determines the actual soil texture. • There is virtually an unlimited number of soil types possible • A moistened soil sample in your hand and squeeze to determine the way it will clump or ribbon. • Jar Method with Depth of Layers. • Soil absorbs and holds water similar to a sponge. • A given texture and volume of soil will hold a given amount of moisture. • The intake rate of soil will determine the maximum precipitation rate without run off of sprinkler or emitting device. • Soils ability to hold and store moisture will affect the irrigation operational schedule.
