7+ Easy Ways: Calculate GDU (Growth Degree Units)

Growing degree units (GDUs), also known as growing degree days (GDDs), are a heat accumulation measure used to predict plant development rates. They are calculated by taking the average of the daily maximum and minimum temperatures, subtracting a base temperature the minimum temperature required for growth of a specific crop and summing these values over time. For example, if the base temperature for corn is 10C (50F) and the daily high and low temperatures are 25C (77F) and 15C (59F) respectively, the GDU accumulation for that day is [(25 + 15)/2] – 10 = 10 GDUs.

This method provides valuable insights into crop maturity, allowing growers to make informed decisions about planting, irrigation, fertilization, and pest control. By understanding the heat accumulation patterns, farmers can optimize crop yields, predict harvest dates, and adapt their practices to changing environmental conditions. Historically, GDUs have been a vital tool for agricultural planning, facilitating the development of region-specific planting calendars and contributing to improved agricultural efficiency.
