The land of the project region that falls in Rajkot district is mainly divided into two types: Salty land is mainly the type of land in Morbi and Maliya and black, loamy soil is mainly present in Jetpur and Dhoraji talukas. The soil of the project region that falls in Jetpur taluka is red soil. In Junagadh district, the soils are formed partly from sedimentary rocks and partly from igneous rocks. They are calcareous in nature, rich in potassium content but deficient in nitrogen and humus. The main types of soils in the district are black, medium black, alluvial soil in the lowlying area, calcareous and brackish. The black soil is found in parts of Vanthali, Manavdar and Keshod talukas excepting the Ghed area. Most of the villages in Junagadh, Malia talukas have medium black soil. The alluvial soil in the low-lying area, known as ‘Ghed’, comprises parts of Keshod, Mangrol and remains inundated during monsoon. The brackish soils are mostly found near the coastal belt of Mangrol, Malia and Veraval talukas and represent the degeneration of Dhoraji Junagarh Maliya Talala Malia Miyana Morbi Una Jasdan 4-4
