For Excellence, the student needs to report comprehensively on the environmental impact of the production of a locally produced primary product.

This involves a concise, coherent and accurate evaluation of the overall impact of the production of a locally produced primary product on the environment. The overall impact includes the balance between positive and negative impacts.

The student provides a balanced concise report of both the positive (1) and negative effects of dairy production that impact (2) on water, land, organisms and air resources. 

For a more secure Excellence, the student could provide a greater emphasis on the positive impact of dairy production. There is minimal discussion of positive impacts such as providing organic matter for soil organism activity (1). 

For Merit, the student needs to report effectively on the environmental impact of the production of a locally produced primary product.

This involves a considered explanation of how production of a locally produced primary product impacts on the environment. A considered explanation includes pertinent information extracted from the data about impact.

Throughout the report, the student has considered explanations of the dairy production practices of using nitrogenous fertilisers and the spreading of effluent, and the impacts they have on the water (1) and air components (2) of the environment. These impacts have been backed up by the use of pertinent information extracted from the data (3).

To reach Excellence, the student could write a comprehensive evaluation involving both the positive and negative impacts of dairy production on the local environment.

For Merit, the student needs to report effectively on the environmental impact of the production of a locally produced primary product.

This involves a considered explanation of how production of a locally produced primary product impacts on the environment. A considered explanation includes pertinent information extracted from the data about impact.

The student explains how the use of nitrogenous fertilisers and effluent from dairy production contributes to the degradation of soil, air and water (1). The use of pertinent information has helped to provide more depth to the explanation (2). 

For a more secure Merit, the student could provide a more detailed explanation of how dairy production impacts on the current or long term effects on the environment, and to be reinforced with further pertinent information.

For Achieved, the student needs to report on the environmental impact of the production of a locally produced primary product.

This involves explaining how production of a locally produced primary product impacts on the environment. 

The student explains how nutrients from both fertilisers and effluent when applied to the land during dairy production impacts on water quality (1). Reference is made to bacterial contamination (2) and also to eutrophication (3).

To reach Merit, the student could include a considered explanation utilising pertinent information extracted from the data about the impacts of fertilisers and effluent in dairy production.

For Achieved, the student needs to report on the environmental impact of the production of a locally produced primary product.

This involves explaining how production of a locally produced primary product impacts on the environment.

The student explains the impact caused to soil from compaction (1), and the impact on water from excess nutrients from the management practices of effluent disposal and the application of nitrogenous based fertilisers utilised (2) in dairying production. 

For a more secure Achieved, the student could provide more links between eutrophication and the management practices of effluent disposal and the application of nitrogenous based fertilisers, and links between soil compaction and dairy farming management practices.

For Achieved, the student needs to report on the environmental impact of the production of a locally produced primary product.

This involves explaining how production of a locally produced primary product impacts on the environment.

The student explains superficially how water quality is affected by effluent and fertilisers (1) used in dairy production.

To reach Achieved, the student could expand on the concepts linking effluent and fertiliser in dairy production to the impact on water quality.
