Research has been conducted at Flaxley Agricultural Centre in South Australia to predict phosphorus loss in surface runoff from dairy pastures. Part of the research investigated if the topography base...
Nitrogen, Phosphorus and Carbon Dynamics during Storms in a Glaciated Third-Order Watershed in the US Midwest
DOC nitrate phosphorus hydrology
<
2015/1/16
The characterization of the nutrients nitrogen, phosphorus and carbon (NPC) export to streams during storms is an integral part of understanding processes affecting water quality. Despite the fact tha...
NITROGEN AND PHOSPHORUS CYCLING IN MIDWESTERN AGRICULTURAL WETLANDS IN RESPONSE TO ALTERED HYDROLOGIC REGIMES
Wetland soil Midwest agriculture
<
2015/1/16
The transfer of nutrients from US Midwest croplands into surface waters causes eutrophication and a decline in water quality. Temporary retention of nutrient-rich runoff in constructed wetlands can he...

Atmospheric inputs of phosphorus and nitrogen to the southwest Mediterranean region: Biogeochemical responses of high mountain lakes
Biogeochemical responses Atmospheric inputs
<
2014/5/4
We quantified dry and wet deposition of dust, nitrogen, and phosphorus over the southwest Mediterranean region (Sierra Nevada, Spain) and assessed its effects on the nutrient status and the chlorophyl...
Effects of Land Use on the Diffuse Load of Phosphorus and Nitrogen

<
2009/10/28
The diffuse load of phosphorus and nitrogen was studied in 23 small drainage
basins in different parts of Finland between 1965 and 1974. Total phosphorus
and total nitrogen concentrations were analy...
Nitrogen and Phosphorus Fluxes from Finnish Agricultural Areas to the Baltic Sea
Nitrogen and Phosphorus Fluxes Agricultural Areas Baltic Sea
<
2009/10/26
Nutrient losses from small drainage basins were compared to the nutrient
fluxes in small coastal rivers in order to study the representativeness of the
Finnish monitoring network of small basins, es...
