Soil-Site Suitability Evaluation for Soybean in Meghal Irrigation Command Area of Southern Saurashtra Region of Gujarat

The five representative soil pedons were studied for characterization and evaluate for soil-site suitability for soybean in the soils of Meghal Irrigation Command area of Southern Saurashtra region in Gujarat. The soils of study area were moderately alkaline in reaction and highly calcareous in nature. The soils on higher altitude have low pH, EC, CEC and ESP than the soils on lower altitude. The soils over undulating upper pediment (Typic Ustorthents) and coastal plain (Fluventic Haplustepts) were placed in sustainable class S₂ whereas soils associated with upper pediment (Typic Ustothrents), lower pediment (Vertic Haplustepts) and alluvial plain (Calcic Haplustepts) were placed in sustainable with high input class S₃. The soils over Lower Pediment, alluvial plain and coastal plain were marginally suitable (S₃) whereas upper pediment were currently not suitable (N₁) for soybean cultivation. The soils over undulating upper pediment were not suitable (N₂) for soybean cultivation.
