Factors Affecting Soil pH and Salinity in Turfgrass

Properly managing soil pH is foundational to proper soil fertility and overall turfgrass management. When soil pH is less than optimal – either too acidic or too alkaline – the turfgrass is under constant stress and fertilizer nutrients are not utilized to their full extent. An imbalance in soil pH may mean you have to work harder to achieve the playing surface desired and some areas of the course may suffer for no apparent reason. pH is often poorly understood and frequently ignored, even if you recall discussions of chemistry from a college course.

John Kruse, Ph.D., will present soil pH in a way that is relevant to turfgrass management and clearly explain why it is important for your success. Topics covered include:

  • an explanation of the pH scale in turfgrass
  • why an optimal pH matters to good soil fertility and plant health
  • why some soils are naturally acidic and some naturally alkaline
  • how common management practices dramatically affect pH and what you can do about it.

About the Instructor
John Kruse, Ph.D., earned his doctorate in soil fertility and soil chemistry from the University of Georgia. His research focused on nitrogen and carbon dynamics in soils undergoing repeated wetting and drying cycles as well as transformations of subsoil acidity and the effect these changes have on several turfgrass species. Kruse worked for Scotts ProTurf division as a Tech Rep., for a fertilizer manufacturing company and as an assistant professor with an extension and research appointment with the LSU AgCenter in Louisiana before joining Koch Agronomic Services as a research agronomist.
