Explanation of Growing Degree Day Calculator
for fall-planted cover crops!
What it does
This new tool calculates growing degrees for fall-planted cover crops.
Growing degree days (GDD) is calculated as the sum of daily meantemperatures(Tmax+Tmin /2)- base temperature, from the date of planting to the date of the first killing frost. Negative values are counted as zero (i.e. no growth for that day)
Can be determined for any location with a weather station linked to www.farmwest.com
What you input
Weather station of interest
Cover crop planting date
Base temperature (temperature at which plants will not grow significantly;default is zero)
Killing temperature which depends on cover crop, default is zero; Note that killing temperature uses average daily temperature not minimum (night) temperature.
To find corresponding temperature data, follow the links to the BC AgriWeather website.
What you get
Current year and historical average dailyGDD, calculated from the date of planting to the current date or to the date at which killing temperatures occurred
Current year and historical average cumulative growing degree days Note: The date on which the selected weather station began providing data is indicated.
When to use GDD calculator
Choose appropriate cover crop planting date
Choose cover crop species to suit anticipated GDD for your area.
Game with the effect of planting earlier or later
Estimate growth of current cover crop by trackingGDD from date of planting Note: Other key factors that determine cover crop growth, such as precipitation, are not considered
