Abstract: The research was conducted during two summer seasons of 2009 and 2010 at the Demonstration Farm of the Faculty of Agricultural Technology and Fish Science, University of Neelain, to determine the different between some chemical composition of the soil before and after leaching of salts by irrigation water quantities and tillage treatments. The two water quantities used were crop water requirement + 10% or 20% of the crop water requirement as aleaching fraction. Four tillage treatments namely, disc plow, chisel plow, disc harrow and zero tillage were used. The variables compared were pH, sodium adsorption ratio (SAR), electrical conductivity (ECe) and calcium carbonate (CaCO3). The results indicated that pH and CaCO3 increased but SAR and ECe decreased during the two seasons.
