Modifications to input format code. (version 98.4+)
Management File now has option for multiple removals or additions of residue. But the user must no longer specify residue removal in Yearly Section residue management options (option 5).
If there is a need for multiple residue additions or removals of residue the user must set the flag in the management file under the pcode option (see operations section below)
Silage calculations now based on the harvest cutting height specified in the crop parameters scenario.
English units are available for the abbreviated annual output summary. The user must place an “e” on the first line of the run file when using the DOS interface in order to generate English units.
