Frequently Asked Questions
What is a base temperature?
A base temperature is the minimum temperature below which a specific crop does not grow. Corn is commonly given a base temperature of 10 degrees Celsius, meaning no growth is counted below that threshold.
How are growing degree units used?
Daily growing degree unit totals are added up across a growing season to track crop development and predict maturity dates more accurately than calendar days alone, since plant growth depends more on accumulated heat than on time.
Can this result be negative?
Yes. If the average of the daily high and low falls below the base temperature, the result is negative, which is normally treated as zero growth for that day rather than a true negative accumulation.
