                  2.   What do you mean by land capability? Discuss the management requirements
              for land capability Classes I, II, III, and IV. Why should lands of capability
              Classes VII and VIII be left under their natural state?
               3.     Define soil fertility, soil heath, soil productivity, soil resilience, soil performance,

              and soil quality. Explore relationships among them. Compare characteristics of
              soil quality of Classes I and IX.


                  4.   What are the causes of soil degradation? What are the types of soil degradation?
              Discuss the extent of global soil degradation.


                  5.   Discuss the institutional initiatives for the assessment of global soil degradation.
              Mention the laws of sustainable soil management.
