Abstract: The present study was carried out by collecting 100 representative soil samples from tobacco growing soils of Prakasam district. The soils were found to be neutral to moderately alkaline in reaction. All the soil samples were non-saline. CaCO3 ranged from nil to medium. The soils of the region were low to medium in organic carbon. The exchangeable calcium was found to be the most dominant cation followed by magnesium, potassium and sodium on soil complex. The cation exchange capacity of the soils varied from 7.80 to 49.26 with a mean of 31.83 cmol (p+) kg-1. The soils showed the mean values of per cent saturation of Ca, Mg, K and Na were 64.93, 12.37, 8.21 and 7.10 which ranged from 38.75 to 81.34, 2.04 to 24.29, 3.14 to 33.33 and 2.23 to 12.82, respectively. The average per cent base saturation was 93.05 which varied from 67.69 to 99.50.
