Nutrient model

[David Houlder]

Hi grassers...

Does anybody know if there is a nutrient dynamics model written for
grass? The sort of thing I'm looking for is a simple process model that
takes a raster of elevations and simulates nutrient transfer between
cells over time, using the elevation difference between adjacent cells
as a rough estimate of the rate of transfer between them.

The whole thing can probably be written in about 200 lines of C I
imagine, but if someone has already done the job (or a better one, for
that matter), it would make my life a little easier.


Thanks in advance
