Human Impact onBiogeochemical CyclesWorksheetSCI/256 Version 6Your neighbor faithfully applies fertilizer to his lawn to ensure beautiful, healthy green grass. Explain how your neighbor’s fertilizing habit affects at least one nutrient cycle.The application of fertilizer by my neighbor affects the nitrogen in the nutrient cycle. Fertilizers are mainly composed of three nutritional components. These components are Phosphorus, Potassium and Nitrogen which are in different compositions for different fertilizer brands.The nitrogen nutrient cycle is the process by which nitrogen goes through the living and non-living aspects of the environment in different forms.In the process of ensuring beautiful, healthy green grass, my neighbor applies excess fertilizer to his lawn. This results in an increase in the amount of nitrogen nutrients in the soil, causing an imbalance in the nitrogen circulation. The organisms that convert nitrogen in the air to ammonia (nitrogen fixing bacteria) and nitrates (nitrifying bacteria) in the soil will not be activated due to the excess amount of nitrogen in the soil. This leads to an excess amount of nitrogen in the air. This excess amount in the air causes a greenhouse effect, while theexcess in the soil causes an environmental condition called eutrophication, which is a surplus of nutrients in soil and water. Eutrophication causes an excess growthof aquatic weeds in water bodies, further causing an imbalance in the ecosystem [CITATION Don92 \l 2057 ].Copyright © 2015 by University of Phoenix.
