Abstract

Application of plant residues as soil amendment is one of the most strategies to improve the physical and chemical properties of calcareous, saline and sodic soils in arid and semi-arid regions. In order to investigate the effect of plant residues application on improvement of chemical properties of calcareous, sodic, and saline-sodic soils, an incubation experiment was carried out as a factorial design with factors including soil type (calcareous, saline-sodic and sodic) and plant residues (corn, sunflower, wheat, trifolium and vicia) along with control treatment (soil without plant residues) in three replications. Plant residues were added to the soils by 2%. Treatments were incubated for 13 weeks at 25° C and 50% of field capacity moisture content. The results showed that electrical conductivity (EC), nitrogen content, cation exchange capacity (CEC), available K, iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn) in treated soils with various plant residues increased significantly (P<0. 01) compared to control treatment. Application of plant residues caused a significant decrease (P<0. 01) in pH and %TNV in treated soils. The concentration of available phosphorus in treated soils with vicia, trifolium and sunflower residues increased by 39, 35 and 18%, respectively, while it decreased in treated soils with corn and wheat residues by 19 and 25% respectively. Application of plant residues increased organic carbon and urease enzyme activity as compared to control treatments to 27 and 134%, respectively. The exchangeable sodium percentage (ESP) of the studied soils decreased by 19%. It can be concluded that, application of plant residues improved the chemical properties of calcareous, sodic and saline-sodic soils, and increased the availability of nutrients. Chemical and biochemical quality of various plant residues are important in improvement of soil chemical properties.
