To impart knowledge to the students on the Fundamentals of Soil Science and impart skills in collecting and analyzing soils for basic physical, physico-chemical and chemical properties for using it as a medium for plant growth.
By the end of the course, the B.Sc.(Ag) students will be able to
i.Understand the fundamentals and principles of Soil Science
ii. Explain how different soils are formed and how does soils act as a medium for plant growth.
iii. Explain soils of India and Land use capability, soil pollution and its effect on crop and mitigation of soil pollution
iv. Analyze the soils for basic physical, physico-chemical &chemical properties.
