Sodium and its Management for Turf

Mar. 1, 2017
10 a.m. (Central)

David Kopec, Ph.D.

Salinity and sodium hazards in soils and water are two fundamentally different aspects of irrigation water quality. In this 90-minute webinar, David Kopec, Ph.D., the extension specialist at the University of Arizona in Tucson, will cover the second topic, sodium. The webinar will address in practical terms, the measurement of sodium in water and in soils. Kopec will discuss the consequences of having a sodic soil, the recognition of plant stress, how to manage sodium effected irrigation water, and how to remediate a sodic soil condition. This webinar will demonstrate the simple calculations often used in sodium assessment and management, as well as their joint interpretation.

After attending this program, attendees will be able to:

  • Understand the origin of sodium in water and in soils.
  • Understand the detrimental effects of sodium on soil structure.
  • Discern potential impact of the salinity / sodium interaction on water infiltration.
  • Understand the differences between sodium and salinity a major stumbling block in the turf industry.
  • Clarify the mystery of carbonates and bi-carbonates as they relate to sodicity.)
  • Interpret water quality components for sodium assessment (SAR, RSC).
  • Calculate the RSC (not always on a water test report).
  • Remediate a high sodium content soil.
  • Identify and use the best amendments for sodic soil remediation and water treatment.

Salinity and its Management for Turf is available On Demand.
