A field experiment was conducted on the sodic soil at
research farm of Soil Salinity Research Institute, Pindi
Bhattian during the year 1998-1999. Undisturbed soil
samples from the four repeats were collected for bulk
density and hydraulic conductivity. The disturbed samples
were also obtained, air-dried, ground, mixed, passed through
2-mm sieve and analyzed for their chemical and physical
characteristics
