In this study the K, U and Th radionuclide concentrations were determined in a sugar cane plantation that received large quantities of fertilizer and gypsum. Geochemical data were obtained for the clay, iron and organic matter in the soil samples, taken from depths of 0-20 and 20-40 cm. The average radionuclide concentrations were 71 Bq Kg(-1) for K; 5.97 Bq Kg(-1) for U, and 11.26 Bq Kg(-1) for Th, and the uranium was variable (56%). The radionuclide average concentrations for the different fertilizer compositions varied in the range of 603.5-8855.0 Bq Kg(-1) for K; 27.3-684.4 Bq Kg(-1) for U, and 58-788.5 Bq Kg(-1) for Th, and it was most variable for K (53%). Gypsum average concentrations were 82.6 Bq Kg(-1) for K, 641.5 Bq Kg(-1) for U, and 201.7 Bq Kg(-1) for Th, and it was most variable for K (46%). Average organic matter, clay and iron concentrations for both the depths were 0.71 and 0.68%; 16.2 and 16.9%, and 29.0 and 26.8 mg/l respectively.
