 The start of the growing season/​sowing date (//bd2//) may be given as a constant, or calculated dynamically depending on temperature. This is set by a model option. If the growth start is dynamically determined it is set to the first day of the year which has a degreeday sum (//GDD//) above a threshold (//​gddsow//​). The start of the growing season/​sowing date (//bd2//) may be given as a constant, or calculated dynamically depending on temperature.
