Operation Brock in Kent is still holding lorries on the M20, A20 and A2, while delays at the port of Dover affect commercial traffic. Pleas from the British Meat Processors Association, to allow vehicles with perishable food to jump the queue, have fallen on deaf ears, and the group is warning that the hold-ups could affect longer-term trade with the EU. The latest figures from land agents Strutt and Parker say the average price of arable land is now £9,500 an acre, and for pasture it's £7,5000 an acre. The price and availability of land is often a barrier to new entrants wanting to join the industry. We hear from one couple who have been trying to buy a farm for 7 years, and from another, who have started farming with no land at all, by grazing livestock on other people's land.
