You've chose the right option to apply for Uni even if you decide not to go, it's keeping your options open. I went down the Uni route at 23 after working on the farm from 16. I would say look at the bigger picture, what do you want to do. I love farming but didn't want to be 65 years old and crippled from working outdoors all day, so I went and did an Ag degree. Working during the holidays meant I left with only a £9,000 debut. Now I work part time on the farm and have a professional job, best of both worlds. The degree for me was the best choice as it opend many doors for potential employment that farming experience alone would not allow me to do. Ask yourself what do you want to do with the rest of your life, when we're young we love driving tractors, calving, milking, lambing etc; but will you want that at 40 / 50 with a family, or would you like good working hours, decent money, and plenty of time off? If you're happy with farming then a degree maybe not for you, but look at the bigger picture.
