Soil-Site Suitability Evaluation for Oil Palm in the Soils of Khammam and Bhadradri Kothagudem Districts of Telangana

Abstract

Soil is an essential natural resource that sustains the life-supporting system of a nation and influences the socio-economic progress of its population. As demand for land rises, land assessment has gained significance as individuals aim to optimize the use of scarce land resources. Land evaluation involves assessing how land performs for specific uses. Five unique soil profiles (pedons) from the oil palm (Elaeis guineensis Jacq.) farming zones in Khammam and Bhadradri Kothagudem districts of Telangana were examined and classified. These soils were evaluate soil suitability for oil palm in soils of Khammam and Bhadradri Kothagudem districts of Telangana using as per the guidelines given in FAO land evaluation frameworks . The soil properties were correlated with crop suitability criteria and relatively better soils were identified for frame work development. The soils belong to Alfisols and Inceptisols soil orders. According to the proposed criteria (frame work) evaluated Aswaraopeta, Apparaopeta, Gattugudem, Buggapadu and Chandrugonda soils and assesed current suitability as marginally suitable (S3) with climatic factors such as annual rainfall and relative humidity and soil fertility factors (pH, organic matter) being common limitations for all the pedons. The suitability classes can be improved if the correctable limitations (Soil fertility characteristics) are altered through soil amelioration measures. Potentially all the pedons were evaluated to be moderately suitable (S2) for oil palm production due to limitations that can be corrected such as soil fertility, drainage by following appropriate measures. Management techniques, including conservational tillage and manure application, which improve the physical and fertility qualities of the soils.
