Web24 de dic. de 2024 · The phosphorous cycle is affected by human activities. Although phosphorous is normally a limiting nutrient, most agricultural fertilizers contain phosphorous. Run-off and drainage from farms can flood aquatic ecosystems with excess phosphorus. Artificial phosphorous can cause over growth of algae and plants in aquatic ecosytems. WebAs the bodies and wastes of organisms break down, they become compacted into layers of soil and rock, returning phosphorus to the environment. Humans influence the phosphorus cycle by using animal waste and phosphate sediments to make fertilizer, detergent, and other products. When these products are released into the environment they can enter ...
