Surendranagar district lies in the north of Saurashtra, on the edge of the Little Rann of Kutch. The district headquarters, Surendranagar city, is joined to Wadhwan, and the district includes Dhrangadhra, Dasada, Patdi, Lakhtar, Limbdi, Chotila, Sayla, Chuda, Muli, Thangadh and others as talukas. Ahmedabad, Patan, Kutch, Morbi, Rajkot and Botad are its neighbours, so a truck that leaves a yard soon crosses a district line. Dhrangadhra is a junction on the Western Railway, and the roads from Ahmedabad toward Rajkot and Kutch run through the district. Rainfall comes mostly between June and September.
Salt is the trade most people link with the district. Salt pans spread across the Little Rann, with the pans near Kharaghoda and the desert area at Zinzuwada often mentioned, and the pan workers pump seawater into the fields after the monsoon and let the sun do the work. The Rann floods from about July and the water goes down by October, after which panning and loading begin, and trucks then carry salt to ports and to buyers inland. Dhrangadhra is also home to a large chemical works, started in the 1930s, with soda ash among its products, and the town is known for its stone carving.
Cotton is the other pillar. Wadhwan and the nearby towns have a long history of ginning, pressing and trading, and Surendranagar has had a cotton and oilseed exchange since the 1960s. After harvest, yards fill with bales and seed, and hired trucks and tractor trolleys move them between villages, mills and market yards. Many vehicles belong to small owners who lend or share them. For such owners a tracker that moves from one trolley to another in a minute is more practical than a wired unit that must be fitted to one vehicle by a technician.
