Task:Read the above article by Lanigan & Hackett, Teagasc (2017)

on how to improve the soil’s organic carbon component.

1. How is soil organic matter (SOM) formed?

2. What is meant by the sequestration of carbon? What is its role in the

soil?

3. How much carbon do global soils contain?

4. Why has SOM been positively related to soil fertility?

5. Explain the role of SOM in plant productivity (biological, chemical &

physical)

6. Explain 3 ways of increasing organic C in croplands.

7. Describe 4 ways to increase organic carbon in grassland using good

agricultural practices.

8. After reading the article, in your opinion, does improving soil organic

carbon maintain a healthy environment for plants & soil micro –

organisms? Explain your answer.
