Explain the nitrogen cycle (with reference to agricultural practices) and supplement by using the simplified diagram suggested below.
Discuss how nitrogen fixation in the soil occurs through natural processes and how it can be carried out artificially through the usage of fertilizers.
Discuss the role of microbes in the nitrogen cycle.
Discuss the resultant emission of a GHG nitrous oxide (N2O) by the application of nitrogen (N) fertilizers.
Explore the nitrogen cycle (with reference to agricultural practices) and supplement by using this simplified diagram N Cycle.
Microbes play an important role in natural nitrogen fixation in the soil. The process of nitrogen fixation in the soil can be carried out artificially through the usage of fertilizers.
The bacterial actions on N fertilizers added to the soil can cause the emission of nitrous oxide (N2O) to the atmosphere.
