What is GDD? (Growing Degree Days)

Turf responds to temperature, not fixed calendar dates.

Calendar dates repeat every year, but spring and summer temperatures can vary dramatically.
GDD is a biological clock for turf, calculated by accumulating the effective temperatures needed for growth.

About Growing Degree Days (GDD)
Biological clock for plants

Growing Degree Days (GDD) accumulate the daily effective temperatures that support turf growth. This helps predict the optimal timing for plant growth regulator (PGR) effects, reapplication, and disease or pest outbreaks. Meissa Green provides a course-specific GDD monitoring algorithm that reflects temperature conditions and regional weighting factors for Korean cool-season and warm-season turf, including bentgrass and zoysiagrass.

International Standards for Turf Management

The USGA and PGA Tour tournament courses have already adopted data-driven turf management based on accumulated temperature as an official standard. In Korea, it is also a core function within the course management and three-structure transition strategies proposed by the Korea Golf Course Business Association (KGBA).
