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?”
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.
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”
