Characterization, Classification And Evaluation Of Chilli Growing Soils Of Khammam District, Andhra Pradesh

Abstract

Typical pedons representing major land forms of chilli growing soils in Khammam district of Andhra Pradesh were characterized, classified and assessed for their nutrient status. The depth of soils was moderately shallow to deep, yellowish brown to dark red in colour, sandy to clay in texture, slightly acidic to moderately alkaline, non-saline, low in organic carbon content and low to medium in cation exchange capacity. Soils are low to medium in available nitrogen and phosphorus, low to high in available potassium and high in available sulphur. However, the soils were deficient in DTPA-extractable Fe, sufficient in DTPA-extractable Zn, Cu and Mn. However the Entisolpedons did not show the presence of any diagnostic horizon. As per soil Taxonomy, Chintakani, Kusumanchiand  Khammam rural, profiles were classified as Alfisols, Palvancha, Bhadrachalam, Chandrugonda and  Wazeedu were classified as Inceptisols and Wyra, was classified as Vertisol.
