Characterization, Classification and Evaluation of Cashew Growing Soils in Coastal Odisha for Sustainable Production

Abstract

Four major soil series (Jharokuali, Kumaradapalli, Ranibara and Kantiagada) representing the cashew growing soils in coastal Odisha, which are developed from different parent materials were studied for their morphological, physico-chemical properties and their suitability for cashew production. Soils are moderately deep to very deep, well drained, texture varied from sand to sandy clay. The soils are slightly acidic to moderately alkaline in nature. A cation exchange capacity is low. Plant available nutrients status of soils are low in N, low to high in available P and K. The DTPA-extractable Fe, Cu and Mn were sufficient. Available Zn is sufficient in surface horizons while deficient in subsoils.The soils at the order level are classified as Alfisols and Entisols at sub group level as Typic Rhodustalfs, Typic Haplustalfs and Typic Ustipsamments. Interpretative groupings for Land Capability, Land Irrigability and Suitability were assessed and identified soil related constraints and suggested appropriate managements measures to improve Cashew productivity.
