14. New Features in TIPSY & BatchTIPSY v 4.2
well-spaced trees
juvenile wood
biomass and carbon output
Enhanced features:
expanded input options for genetic improvement
choice of relative or absolute fertilizer response
relaxed constraints on custom response
capability to import a file with custom fertilization responses
capability to import a file with custom OAF specifications
updated economics and jobs modules with 2006 values

15. Fertilization Modelling Future Needs........
update Ministry standard response values for:
Fdc, Pl, Sw, Fdi
develop Ministry standard response values for:
Hw, Ss, Cw, Ba, Bl
weighted fertilization response over response period
individual tree biomass equations for fertilized trees
more fertilization research on sites/stands/species not covered by existing trials
