Abstract

To study the effects of different levels (0, 2.5 and 5%) of alfalfa residue with and without gypsum or aluminum sulfate on chemical properties of a SODIC SOIL, a greenhouse experiment with 9 treatments was conducted using a completely randomized design and three replications. After addition of treatments to soil samples, they were incubated for four months at moisture content of field capacity. The results showed that 2 and 4 months after incubation, treatments with 5% alfalfa residue + aluminum sulfate and 5% alfalfa residue + gypsum increased the electrical conductivity of soil samples significantly. Treatment with 5% alfalfa residue + aluminum sulfate decreased the pH values of soil samples to 1.36 and 1.55 units compared to control 2 and 4 months after incubation respectively. Treatments with gypsum and aluminum sulfate decreased water DISPERSIBLE CLAY to 89.43 and 93.03% compared to control after 4 months of incubation respectively. Treatment with 5% alfalfa residue increased water DISPERSIBLE CLAY by 4.8 and 2.2% 2 and 4 months after incubation respectively. Similarly, these treatments decreased sodium adsorption ratio respectively by 54.19 and 43.85% compared to control 4 months after incubation but treatments with 2.5 and 5% alfalfa residue increased sodium adsorption ratio respectively by 0.7 and 3.83% compared to control after 2 months of incubation.
