Fall weather is coming, and that should bring changes to your plant growth regulator applications. For over a decade, we’ve known that PGRs – and even DMI… Read more “Be Careful with Fall Growth Regulation”
Author: Bill Kreuser, PhD
Bill Kreuser invented GreenKeeper App in 2015 to help turfgrass managers make agronomic decisions. He received his BS and MS in Soil Science from the University of Wisconsin-Madison and PhD from Cornell University in Horticulture. Bill created the first PGR GDD models with Doug Soldat, PhD in 2008 and has continued to create new PGR and DMI models. His other research emphasis is precision turfgrass management through the use of models and sensor data.
Mixing PGRs can transform your putting greens
Doug Soldat and I have been developing PGR growing degree day (GDD) models since 2008. These models have helped turfgrass managers understand how clipping yield – a.k.a.… Read more “Mixing PGRs can transform your putting greens”
Soil Organic Matter Models Aid Cultivation Scheduling
Managing soil organic matter (SOM) is a primary concern for turfgrass managers. Unfortunately, changes in SOM through cultivation happen over the course of months and years. This… Read more “Soil Organic Matter Models Aid Cultivation Scheduling”
Clipping Volume vs. PGR GDD Models: Which is more important?
I received an interesting question following a plant growth regulator (PGR) programming webinar. The webinar covered introductory PGR topics including: PGR degradation and removal, prediction of PGR… Read more “Clipping Volume vs. PGR GDD Models: Which is more important?”
Spiio Soils Data to Drive Pest Models in GreenKeeper
Data has transformed turfgrass management. Relatively new tools such as hand-held soil moisture meters have helped turfgrass managers improve irrigation decisions for over a decade. As we… Read more “Spiio Soils Data to Drive Pest Models in GreenKeeper”
