!     cropno - number that identifies the crop to be grown
!     fracarea - fraction of area tilled (not implement but field?) (m*m)
!     tdepth - tillage depth (mm)
!     trdflg - tillage ridge flag
!     imprs  - implement ridge spacing (can be used to set row spacing)
!     ospeed - operation speed (m/s)
!     odir - operation direction (degrees from NORTH)
