We will discuss the pros and cons of some of the latest "Smart" control systems on the market. We will delve into why some people are successful and others are not when using these systems. We will also look at communication options for these systems, cloud management, flow sensing and rebates.
"The seminars were all great. Presentations ranged from highly professional to accessible for those who want to gain general knowledge."
Did you know that between 80 - 90% of plant disorders are the result of irrigation related issues rather than from plant diseases or insects? Even during the drought many landscape trees and shrubs are overwatered leading to a lack of oxygen in the root zone which can kill a plant. In other cases, overwatering leads to the infection of roots and crown by plant pathogens such as Phytophthora or Cytospora spp. Other non-pathogenic disorders (called abiotic disorders) are the result of too little water after transplanting, herbicide drift from neighboring sites, lack of light, lack of air circulation around mature plantings, or construction damage too close to plant roots. Janet Hartin will discuss how to identify and prevent these important issues during her talk.
Last year I spoke about the trend of flow meters in the irrigation industry as well as others. This talk included the many aspects of performance improvement, and that the irrigation industry should be aware that better choices are now available.
This year, I would like to follow up with a detailed discussion on how to choose the right flow meter. This would include several pieces of criteria that will ensure the application is best served.
Most salts in irrigation water are managed and not controlled. However, it is feasible to control both high bicarbonated and high ph with acids. High pH and bicarbonates will affect water quality and often limit plant health, color and productivity. The presentation will focus on why adjusting irrigation water pH is important, with emphasis on maintaining pH at 6.5 to 7.0, on a continuous basis.
This class teaches technicians the general skills of troubleshooting an electrical irrigation system through the use of basic electrical equipment. It includes general instruction on the function and uses of a voltage ohmmeter and shows you how to use wire-tracking equipment to locate wire faults in the field. The class goes from testing the transformer of a controller to checking the ohms of a solenoid and all other functions of testing the irrigation electrical system. The advanced field-study class teaches technicians specific skills in troubleshooting an electrical irrigation system. Technicians learn to use state-of-the-art wire and valve locators and pulse ground fault locating equipment through practical, hands-on application to locate wire faults in the field. Classroom instruction is a minimum of one hour, including instruction on the function and uses of a voltage ohmmeter. The focus is hands-on field training using the necessary equipment for the remainder of the class.
Explore the long overdue wireless control and monitoring revolution with the experts in the field. Learn how to survey for and deploy wireless irrigation control systems, wireless flow sensors, wireless pump start interfaces, wireless pressure sensors and wireless soil moisture sensors and probes.
Learn how the systems work and how they can cost effectively solve a vast array of daily irrigation control challenges. Make the unfeasible, feasible by leveraging the power of modern wireless technology to reduce labor, equipment expense, construction timelines and on-site disruption.
Irrigation requirements for turfgrass are most of the time miscalculated. Incorrect irrigation practices lead to overabundant water applied to turf, setting ground for turf removal campaigns in the desert Southwest. As water resources inevitably decline due to population growth and resultant irrigation requirements, water use must necessarily be reduced, especially during drought. The primary objective of the seminar is to help quantify the amount of water required to keep turfgrass green and functional in California. The seminar will review the benefits of having natural turf vs. artificial or no turf, and will include the last results from studies that calculated irrigation requirements on different turf species and cultivars conducted at the University of California, Riverside. Secondarily the study will focus on strategies to reduce potable water consumption to irrigate turf areas, and to identify the right species to be grown in Southern California. For instance, warm-season turf species are known to be more water use efficient and drought tolerant than cool-season turfgrasses; nevertheless, tall fescue remains the predominant species used in California lawns
Drip systems can provide highly efficient irrigation results, but they have unique challenges in design and layout. If you have experienced issues with pressure, uneven performance, problems with plant establishment, problems with fertilizing a drip irrigated landscape or just wondered how to use all of those charts and information that manufacturers provide, then this class is for you. We will get hands on with product and we will design / lay out a drip system correctly.
Class will discuss the proper techniques to repair and service backflows. Disassembling backflows, reassembling, and testing for proper function. This class will also discuss the intricacies of field-testing the pressure vacuum breakers, spill-resistant vacuum breakers, double check valve assemblies and reduced pressure principle backflow prevention assemblies.
The Landscape Expo is a regional trade show and educational conference for landscape professionals from all facets of the industry. Featuring hundreds of exhibitors and thousands of attendees every fall for the past 60 years, the Landscape Expo is the premiere event for landscape professionals in the western United States.
