10. Why is the organic mater content in the primary forest higher than that in the
secondary forest and that in the secondary forest higher than that in agricultural
land? Explain!
11. How can the soil tillage systems affect the soil organic matter contents. Explain!
How this practice affect the soil enzymatic activities?
12. Explain the relationship between the activities of soil enzymes and soil total N!
Why?
13. Is it possible to set the activities of soil enzymes by regulating some soil chemical
properties such as organic C and total N? How? Explain!
