Department of Soil and Water Science
Yezin Agricultural University


The department of soil and water science (DSWS) is one of the thirteen major departments providing both undergraduate and postgraduate students in YAU. The department was established in 1955-1956. The DSWS prepares the graduates as professional in private and public sector to develop, adopt and disseminate knowledge and technologies that focus on soil-plant-water continuum.

Soil Science and Plant Nutrition

Soil science and plant nutrition specialization provide a holistic understanding of concepts of soil fertility and productivity, soil-ion interaction, integrated nutrient management, microorganisms in agricultural systems, land uses and land-use survey, management of problem soils. The specialization prepares the graduates for sustainable nutrient management and agricultural development.

Water Management

Water management specialization places emphasis on the application of principles and practices of irrigation and drainage, soil erosion and conservation schemes, principles of water conservations including water harvesting and saving techniques, economics in irrigation management and project evaluation. It trains the students as professionals with a broad knowledge of natural resources management.


Building upon its foundation of different expertise, the department of soil and water science initiates heuristic education and shares scientific knowledge for wise use of soil and water resources with the outcome of sustainable soil, plant, water and environment.


The department of soil and water science has to provide innovative teaching, the state-of-the-art research and extension techniques based on societal needs related to the conservation and management of natural resources linked to plant and soil ecosystems, and future prospective water and environment. The total of 27 teachers specialized with Agricultural chemistry, Soil Science, Water management and plant nutrition of Soil and water science department leading with Professors, and 11 non-teaching staff are trying their best for improving department by teaching undergraduate, postgraduate students, by doing research collaboratively with international organization, by going excursion for getting external knowledge, by attending training for teachers for upgrading specialized subjects and English language proficiency.
