Study on potential soils for sugarcane cultivation in Central Plain was carried out by analysis of sugarcane growing area of the Central Plain and properties of soils inclusive of soil morphology, physical and chemical properties and mineralogical characteristics. Other vital characteristics of soils and sugarcane production environments were also noted. Then, comparison was made between soil related parameters and sugarcane crop requirements. Results of the study reveal that potential soils for sugarcane cultivation in the Central Plain comprises soils of various great groups. They include Haplustalfs of Alfisols Haplusterts of Vertisols, Haplustolls and Calciustolls of Mollisols and Dystropepts of Inceptisols. These soils indicate their difference in limitation related to sugarcane crop requirements. Haplustalfs show relatively high potential for sugarcane production in both their physical properties and fertility. Haplusterts, Haplustolls and Calciustolls have suitable fertility but they have some limitation on physical properties related to moisture availability for sugarcane. Dystropepts show the lowest potential for sugarcane cultivation but they can be managed to obtain satisfactory yields of sugarcane by using present soil-fertilizer technology for sugarcane production.
