Redox Potential and the Black Layer On Demand

Lee Berndt, Ph.D.
Start Date
90 Minutes

One job of a golf course superintendent is to manipulate the environment to allow turfgrass plants to make the best of their genetic potential. Some cultural practices can influence redox potential affecting both turfgrass plants and soil microbial communities. Lowering redox potential can lead to development of black layer, which is an accumulation of metal sulfides in pore spaces of soil. In this 90-minute webinar, Lee Berndt, Ph.D., discusses the nature of soil redox potential, its relationship to the health and quality of turfgrass and to black layer formation, and its relationship to soil pH. Managing black layer means keeping redox potential elevated; Berndt will review practices you may want to adjust to reduce the potential for black layer occurrence.
