Sorghum model senescence defect

What happened?

The attached simulation throws the exception:

Paddock.Sorghum.Leaf:                             Emergence
                                                  LAI = 0.00 (m^2/m^2)

135.8 kg/ha of NO3N was added at sowing. The sorghum model is trying to senesce all leaves at emergence so my guess it is severely water stresed.

@peter-devoil - can you look at this?
