Pembrokeshire has good soil and benefits from the Gulf Stream, which provides a mild climate and a longer growing season than other parts of Wales. Pembrokeshire's mild climate means that crops such as its new potatoes (which have protected geographical status under European law) often arrive in British shops earlier in the year than produce from other parts of the UK. Other principal arable crops are oilseed rape, wheat and barley, while the main non-arable activities are dairy farming for milk and cheese, beef production and sheep farming.
