Primary schools are being encouraged to plant their own potatoes next term, as part of a national project. To mark the international year of the potato in 2008, the British Potato Council is asking pupils to chip in and grow their own. All schools that register before February 8 will be given free seed potatoes and a pound;5 voucher towards compost. The council has compiled a range of online education resources. The school that grows the most potatoes will be given a digital camera.
