Highland areas in the north and west of the UK often rely on pastoral farming methods. Sheep farming is particularly suited to hilly areas because sheep can graze on steep slopes and eat rough grass grown on poor soils. Dairy herds need flatter land and a supply of good grass. They tend to be in areas with good links to markets.
Some farms are both arable and pastoral. This reduces the risk because if prices fall for one crop or there are unfavourable weather conditions, there may be another product that can provide food and make money. Animals can also provide manure for the fields and help to maintain soil fertility.
