ABSTRACT
A case study was carried out to evaluate soil suitability for rice and wheat in soils of Chavella mandal of Ranga Reddy district in Andhra Pradesh using limitation method. The soil properties were correlated with crop suitability criteria and relatively better soils were identified for frame work development. The soils belong to Alfisols, Inceptisols and Entisols soil order. Texture, depth, drainage and slope are the major limitations for rice and wheat. The suitability classes can be improved if the correctable limitations (Soil fertility characteristics) are altered through soil amelioration measures. According to the proposed criteria (frame work), P8 is highly suitable P1, P3, P4, P5, P6 and P7 are moderately suitable and P2 is marginally suitable for rice, Whereas P3 and P6 are highly suitable and P1, P2, P4, P5, P7 and P8 are moderately suitable for wheat.
