A leading potato packer has managed to ensure year-round UK supply for main crop potatoes. Tesco supplier Branston potatoes has already begun lifting Marfona three weeks earlier than usual thanks to improved techniques. Field director David Nelson said: "As well as improved production and harvesting, it's also down to a process of lifting, rapid cooling and fast packing." Using the same techniques on Maris Piper, Nelson said it had managed to eliminate any imports to plug gaps in the UK main crop market. {{MARKET EDGE }}
