Hi ross,

The maize crop doesn't listen to a grazing or removal event, so you're out of luck.

However, you could send the SOM module a custom tillage event that will get rid of the biomass that never should have got there, eg:

'surface organic matter' tillage type=user_defined, f_incorp = 0.95, tillage_depth=0.0

Yours,
pdev

PS There's a new maize module coming next year that may behave differently.
