Abstract : Seven typical pedons in Yerpedu Mandal of Chittoor district, Andhra Pradesh were evaluated for their suitability to groundnut, sorghum, maize, sugarcane, paddy and mango. The major limitations in Ultic Haplustalfs for different crops are soil texture, base saturation and organic carbon. In Typic Haplustepts and Typic Ustipsamments, the limitations are mainly due to soil texture, base saturation, pH and organic carbon whereas, soil texture, pH and organic carbon are the factors causing major limitations, in general, for all the crops in Typic Ustifluvents. The limitation levels of the land characteristics varied from crop to crop. The suitability classes can be improved if soil fertility characteristics are improved.
