Examining the link between terrestrial and aquatic phosphorus speciation in a subtropical catchment: The role of selective erosion and transport of fine sediments during storm events

Distribution and Environmental Significance of Phosphorus Forms in Riparian Soils and River Sediments of Jianxi Basin, Fujian Province

“…According to the administrative division, Jianxi Basin belongs to Nanping City, which includes six counties and a total of 66 villages and towns. Specifically, the six counties are Wuyishan, Jianyang, Pucheng, Songxi, Zhenghe, and Jian ' ou, which consist of 7,11,17,8,9, and 14 towns, respectively. Among the three major water sources, the Chongyangxi flows through Wuyishan, Jianyang, and Jian ' ou counties, being home to the most developed tourism with the highest tea garden coverage and catering industry; the Nanpuxi flows through Pucheng and Jianyang with more industries and vegetable fields distributed along its coast; the Songxi flows through Songxi, Zhenghe, and Jian'ou with a relatively small population, the largest forest land area, and developed crop farming [20][21].…”

“…At present, many domestic and international scholars have done a lot of research concerning the distribution of phosphorus fractions in sediments [16][17]. But most of them are focused on relatively broad water such as lakes, reservoirs, and gulfs under eutrophication state, and relatively insufficient study has been dedicated to river basins [13].…”

Science to Support Management of Receiving Waters in an Event-Driven Ecosystem: From Land to River to Sea

“…Sources, forms and transformation of phosphorus, for example, have been identified in the catchment of Wivenhoe reservoir, the major source of drinking water in SEQ. Contrary to common belief, much of the phosphorus running off the catchment is in the dissolved inorganic form or loosely bound to soils owing to release from soil during wetting events [28][29][30]. As a result, the phosphorus can directly stimulate phytoplankton blooms, although the spatial and temporal scales over which this occurs depends on the turbidity of inflowing waters (which alters light availability) and the size, timing and source of those waters [19].…”

Transferência de nitrogênio e fósforo para águas superficiais em uma bacia hidrográfica com agricultura e produção pecuária intensiva no Sul do Brasil

“…Todavia, a aplicação sucessiva de dejetos em altas doses promove a saturação dos sítios de sorção de P no solo, resultando na alta disponibilidade desse elemento, sendo facilmente transferido à fase solúvel quando esses sedimentos são transferidos aos corpos d'água (KERR et al, 2011) trabalho, foram determinadas as concentrações de P solúvel e nitrato nas águas dos canais de drenagem de uma bacia hidrográfica com agricultura e produção pecuária intensiva do Sul do Brasil, a fim de avaliar os impactos que as atividades agropecuárias podem causar no ecossistema aquático.…”
