GreenKeeper Models Provide More Insight Than Simple GDD Calculators

​I first learned about growing degree days (GDDs) in my introductory agronomy course at UW–Madison. These models used daily average temperature to predict biological processes such as corn development. I later learned that GDDs could also be used to schedule seedhead...

Upgraded GreenKeeper CIS Includes POGO Integration

Many turf management decisions are inherently spatial—where water is needed, where pests typically occur, and where additional management is required to achieve specific performance goals. Historically, these patterns have been managed through careful observation,...
