Do you have a green solution to pasture weeds?

Q: I take care of the family pastures (maintain irrigation) and was wondering what is the best way to get rid of weeds in the pastures. We have horse weed and a few others, not real bad but want to stop it and get rid of it. The family does not want to use chemicals as we are right on the Metolius river.
