Dynamics of Soil Physicochemical Properties under Different Agroforestry Practices in the Dollo watershed, Gamo Zone, Southern Ethiopia

The dynamics of soil physicochemical properties in agroforestry systems can significantly influence crop productivity, soil health, and overall ecosystem sustainability. In the context of the Dollo watershed in the Gamo Zone of Southern Ethiopia, understanding these dynamics is vital for promoting sustainable agricultural practices and enhancing land productivity. This study investigates the impact of various agroforestry practices on the physicochemical properties of soil. Using a comparative analysis, sixty soil samples were collected from multiple agroforestry sites. The results showed that agroforestry type and soil depth had significant effects on soil bulk density, organic carbon, pH, exchangeable potassium, electrical conductivity and cation exchange capacity. The results indicated significant variations in soil physicochemical properties across different agroforestry practices and soil depth, with certain agroforestry systems enhancing soil fertility more effectively than others. Home garden agroforestry practices were found to have higher soil organic matter content than the other types of agroforestry. These findings underline the importance of selecting appropriate agroforestry practices to improve soil health and agricultural productivity in the area. Based on these results, integrating agroforestry with traditional farming methods can result in synergies that benefit both people and the environment. Continued research and extension efforts are needed to promote these sustainable practices effectively.
