The correct answer is: Southwest.
Sandy soils are found in the southwest of Haryana, in the districts of Gurgaon, Rewari, Mahendragarh, and Jhajjar. These soils are derived from the alluvial deposits of the Yamuna River and its tributaries. They are light-colored, well-drained, and have a low water-holding capacity. They are suitable for growing crops such as wheat, rice, and cotton.
The northeast of Haryana is covered by the Shivalik Hills, which are composed of sandstone and shale. The soils in this region are deep, well-drained, and have a high water-holding capacity. They are suitable for growing crops such as rice, sugarcane, and maize.
The Yamuna River flows through the central part of Haryana. The soils along the river are alluvial and are very fertile. They are suitable for growing a variety of crops, including wheat, rice, sugarcane, and maize.
