How has human activity altered the phosphorus cycle

How Has Human Activity Altered The Phosphorus Cycle. Like other biogeochemical cycles human activities have altered the phosphorus cycle. PHOSPHOROUS CYCLE Human activities increase phosphorous concentrations in surface waters through substantial runoff of the phosphorous rich fertilizers we apply to lawns and farmlands. Aquatic ecologists are becoming increasingly aware of the importance of these indirect alterations to biogeochemical cycles. Huge quantities of sulfuric acid are.

As phosphate are released in small amounts in its accessible form in its original natural cycle this extra phosphate released by human activities results in a change in the original phosphate cycle. The transformation of the global phosphorus cycle is just one example. This extra phosphate in water bodies are also a major contributor to the process of eutrophication which causes excessive growth of water plants and algae populations. Here we examined magnitudes of which humans have altered the P cycles by integrating the estimates from recent. Like other biogeochemical cycles human activities have altered the phosphorus cycle. Mostly through the addition of phosphate-based fertilizers and mining phosphate rock.

While natural P mobilization is slow humans have been altering P cycle by intensifying P releases from lithosphere to ecosystems.

Human Impact on the Phosphorus Cycle. Human beings mine phosphate rocks and guano deposits to make phosphorus available for production of fertilisers detergents animal feed medicines pesticide. However excess amounts of phosphorous added to soils often leach into groundwater or get into streams that then drain into lakes. We effect the nitrogen cycle by fertilizers burning forests fossil fuels. Mostly through the addition of phosphate-based fertilizers and mining phosphate rock. These activities have served to increase the amount of nitrogen biologically available in the environment.
