Effective Degree Days
In agriculture, it is not calendar days but Degree-days that are used to predict crop and insect development. RIMpro includes a table with the basic accumulation of degree days for different thresholds within the model list.
Differing threshold temperatures and beginning accumulation dates are used to determine accumulated heat units for different crops. The threshold, or base temperature, is the temperature under which no significant crop development is expected. The RIMpro model gives insights into the effective degree days.
