By Bill Kreuser, PhD We first started talking about PGR growing degree day (GDD) models back in 2008. These models use daily average air temperature to estimate… Read more “PGR & DMI GDD Models v2.0”
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.
Growth potential models can improve management efficiency
By Bill Kreuser, PhD Turfgrass response to nitrogen fertilizer depends on many factors like temperature, sunlight, water availability, root health, and soil compaction. Some factors like soil… Read more “Growth potential models can improve management efficiency”
