The province of Palencia in Spain is set to see a record harvest of black truffles, with up to 2,000 kg expected from 20 growers in the Cerrato region. The fungus thrives in the region's stony soil and has benefited from modern farming and irrigation techniques, autumn rains, and the right temperatures. The University of Valladolid is studying the productivity and potential of edible mushrooms and truffles in the region, and has noted a increase in demand for fresh truffles. The truffle cultivation is expected to generate an income of € 700,000 per year in rural villages.
