Course Name : Problematic Soils and Their Management

Code(Credit) : ASSC-3103(1-1-0)

Course Objectives

  • To know about the soil and different problem occur during cultivation. How to identify the problem and what are the reclamation method requires improving the soil health.Students learn practically about the identification of problem soil and learn different method to improve soil fertility, that necessary to improve the yield.

Learning Outcomes

  • The students get knowledge about different kind of problem soil in India and there characteristics
    The students will understand how to control or improve the soil fertility.
    The students gain practical knowledge of laboratory to test the problem soil.
