I'm not an expert in this, but there were plenty of Romans with plenty of time to innovate. And innovate they did. They had significant achievements in engineering and construction. I mean some of their constructions still stand today. They also spent lots of time on other things and got pretty sophisticated (politics, negotiations, war, poetry).
So I'm not really convinced that their agriculture practices would have been an issue...
