suspended sediment resulted from distributed soil erosions facilitates nutrient transportation and influences soil depletion. phosphorus (p) is one of the major limiting nutrients controlling eutrophication of surface water. irregular p load pulsed by heavy rainfall may damage the ecological quality of downstream waters. p transport study during rainfall events is important in both predicting a...

wheat (triticum aestivum l.) was grown in earthen pots containing soil of balkasar soil series (sandy loam) in green house at the department of soil science and swc, pir mehr ali shah arid agriculture university, rawalpindi during rabi season, 2007. the crop was treated with two levels of phosphorus (40 and 80 kg p ha-1 ) in the form of ssp, tsp, np and dap. a basal doze of 100 kg n and 60 kg k...

BACKGROUND The health implications of dietary phosphorus intake and the role of kidney function in managing serum phosphorus homeostasis are well studied. However, examining the source of dietary phosphorus intake and its impact on serum phosphorus has not been characterized in population studies. OBJECTIVE This study aimed to distinguish the association of food sources of organic phosphorus ...

Interest in the health effects of dietary phosphorus is burgeoning, yet sources and trends in phosphorus consumption have not been well characterized. We describe trends in and primary sources of dietary phosphorus in a nationally representative sample of 34,741 US adults, 20+ years old (NHANES 2001-2014). Dietary sources of phosphorus were estimated in nine food groups and 26 food categories. ...

Dam construction causes the accumulation of phosphorus in the sediments of reservoirs and increases the release rate of internal phosphorus (P) loading. This study investigated the longitudinal variability of phosphorus fractions in sediments and the relationship between the contents of phosphorus fractions and its influencing factors of the Manwan Reservoir, Lancang River, Yunnan Province, Chi...

[1] Biogeochemical studies show that the surface waters of the subtropical North Atlantic are highly phosphorus (P) stressed. Human activity may exacerbate phosphorus stress by enhancing atmospheric nitrogen (N) deposition and raising N/P ratios in deposition. However, the magnitude of this effect is unclear, in part, because atmospherically deposited phosphorus sources are not well known, part...
