As C is the landcover factor, you would have to look into techniques of 
image classification. There is a large amount of literature on that. In 
GRASS you have i.maxlik or i.smap & co.

The P is the supporting practices factor. AFAIK, this depends very much 
on local practices.


You can have a look at this web site for more guidance on RUSLE and each 
of its factors:
