In this 90-minute webinar Glen Obear, Ph.D., focuses on diagnosis and management of irrigation water problems, which fall into three primary categories:
1) salinity (too much salt),
2) sodicity (too much sodium), and
3) ion toxicity (boron, chloride).
What is the difference between these issues? What analytical tests and measurements do we use to define them as problems? What do those problems mean for you as a manager, and what can we do to manage them? Join Obear for answers to these questions and more. He discusses the latest research on soil layering (bicarbonate, iron-cemented layers) and relationships with water chemistry. To finish, Obear reviews a testing model for the future that incorporates both irrigation water and soil testing into a more holistic view of the complex turfgrass systems you manage.
