density value of 2.65 g cm-3 and particle size analysis
was determined by hydrometer method (Anderson and
Ingram 1998). Organic carbon was determined by the
Walkley and Black (1934) method. Available P was
determined using the method of Bray and Kurtz (1945),
while pH was determined potentiometrically in 0.01 M
CaCl2 solution using a soil to solution ratio of 1:2. Soil
exchangeable cations (Ca, Mg and K) were analyzed
after leaching the soil with 1 M ammonium acetate at
pH 7. Exchangeable Ca and Mg were determined by
atomic absorption spectrophotometer and Mg by flame
photometer. Cation exchange capacity (CEC) was
determined as the sum of exchangeable cations and
exchange acidity. Base saturation (BS %) was calculated
by dividing the sumof the base forming cations by
CEC of the soil multiplied by 100. All analyses were
done in triplicates.
