| Abstract | ||
| The study was conducted in the laboratory of Department of Soil Sciences and Water Resources, College of Agriculture, University of Basrah. The objective of this study was to investigate the effect of salt sand organic matter on boron adsorption in calcareous silty loam soil from south of Iraq. Boron added with six levels (0, 5, 10, 20, 30, 40) mgL-1 to the soil with two types of salts CaCl2.2H2O and NaCl with two levels of organic matter (0 and 4%) as cattle manure. Residual boron concentration was determined by curcumine method and adsorbedboron was calculated. Results showed that boron adsorption in soil significantly increased by increasing of boron concentrations. Higher value of boron adsorption (15.99 mg kg-1 soil) was obtained with4 mgL-1 of boron. Results indicated that organic matter had higher value of boron adsorption as compared with salts. Maximum boron adsorption was 10.18 mg kg-1 soil in organic matter treatment. Also calcium chloride treatment obtained higher value of boron adsorption (8.95 mg kg-1 soil ) than sodium chloride (6.95 mg kg-1 soil). | ||
