Final answer:
Phosphorous loss from production agriculture and turfed areas can lead to eutrophication in aquatic systems. Eroded soil and sediment can transport phosphorus to rivers and streams.
Step-by-step explanation:
This question is related to the environmental impact of phosphorous loss from production agriculture and turfed areas. While nutritional losses from these land uses do not fully translate into human-available nutrients, the use of phosphorous in artificial fertilizers and runoff from animal husbandry can lead to eutrophication in aquatic systems. Phosphorus enters aquatic ecosystems mainly through erosion, but methods like no-till agriculture and the use of hedgerows can reduce the rate of this process. Eroded soil and sediment can transport considerable amounts of phosphorus and other nutrients to rivers and streams.
