The country’s sole turmeric exchange in Sangli city boasts secrets gained through a centuries-old practice − storing turmeric in pits. These pits stretch far out in the open fields of the villages of Haripur and Sangliwadi. It is possibly the most unusual agricultural commodity−storage system in the country. After clearing the loose soil covering the pit, it is left open for about two to three hours. One cannot enter the pit until one finds out if there is any oxygen within. To ascertain this, a lantern is lowered into the pit. If the lantern does not go out, it is safe to enter the pit. It was this ingenious storage system, devised over 200 years ago, that turned Sangli into a major trading centre for turmeric. Raw turmeric sold by farmers is stored in these pits, eighteen to twenty feet (five to six metres) deep, for three to four years. The pits provide the best storage facility for turmeric, as the quality of the commodity remains unchanged. The turmeric hardens and matures while in storage. Today, more than 80% of the turmeric trade in India takes place in Sangli. Sangli Turmeric Commodity Exchange, Spices and Oilseeds Exchange, Mahavir Nagar, Sangli
