Doctor of Philosophy in Soil Science


    Soil is a key resource in agricultural production, engineering and landscape development, and environmental conservation and management. Accelerated land degradation and desertification through soil erosion, depletion of soil fertility, overstocking, deforestation, poor management of land resources, and climate change are all issues of great concern that are directly or indirectly linked with soil resource exploitation..

    The revised Doctor of Philosophy in Soil Science programme offers comprehensive exposure to the  discipline of soil science as currently practiced. It offers definitive concepts, descriptions, fundamental principles and practices, appropriate methodologies and core knowledge from all fields encompassed within the discipline of soil science. These include pedology, soil physics, soil chemistry, soil biology and biochemistry; and their applications in soil survey and classification, soil fertility and plant nutrition, and soil conservation and water management. The curriculum provides a rigorous, complete and up-to-date presentation of the subject to meet the needs for training and research in soil science for enhancing productivity and sustainability of the soil resources. The revised programme has updated and expanded the content to provide essential new coverage of topics critically important to meet current and emerging challenges in soil science such as intensification of resource use, carbon sequestration in agroecosystems, global warming and climate change.
