We manage it Freerange in that DH & I do it as a 50/50 partnership. He makes all the "practical" decisions, i.e. what crop, where, but we discuss it all and make joint decisions as I have degrees in agricultural/conservation management.
I do all the admin and finance side, including the SFP applications etc, and we are in the process of taking our farm business from a "family subsistence farm" (PIL did the whole money in=money out with not too big an overdraft and were tighter than a ducks arse) to a fully profitable/self sustainable agricultural business with farm investment, diversification and expansion.
I'm very lucky in that DH is very open to new ideas & although has "traditional" farming ideas, sees me very much as an equal - I have equal say, although he has final call on the crop rotation.
Although, DH does have a health disrespect for "book learning" as he put it. We found a farm management plan I wrote for an upland farm for the final year of my degree. When he read it, he was crying with laughter. His best comment was, "Only you would have 200 cows on 120 acres, no staff and spend £72,000 on dry stone walling and £63,000 on fencing!" In my defence, I was using a lot of grants and I was only 20! and thought I knew it all
