Detailed Description

DK_OSpringFodderGrass class
.

See DK_OSpringFodderGrass.h::DK_OSpringFodderGrassToDo for a complete list of all possible events triggered codes by the DK_OSpringFodderGrass management plan. When triggered these events are handled by Farm and are available as information for other objects such as animal and bird models.

Do()

bool DK_OSpringFodderGrass::Do ( Farm *  a_farm, LE *  a_field, FarmEvent *  a_ev  )

virtual

The one and only method for a crop management plan. All farm actions go through here.

Called every time something is done to the crop by the farmer in the first instance it is always called with a_ev->todo set to start, but susequently will be called whenever the farmer wants to carry out a new operation.
This method details all the management and relationships between operations necessary to grow and ALMaSS crop - in this case conventional spring barley Fodder.

Reimplemented from Crop.
