Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/3
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
Impacts of Land Use, Fertilizer and Manure Application on the Stream Nutrient Loadings in the Salmon River Watershed, South-Central British Columbia, Canada
Model Landuse Nitrogen Phosphorus Fertilizer Manure
2013/3/11
Manure and fertilizer applications can increase soil productivity and land economic values, but the controversial result can be a decline of water quality due to the increased nutrient exports from so...
Nutrient-Induced Growth of Coliform and HPC Bacteria in Drinking-Water Pipes
Coliform HPC Bacteria Nutrient Drinking-Water Pipes Biofilm Bacterial Growth
2013/3/11
We conducted a study on a model drinking water distribution system to evaluate the impact of nutrient in the form of sodium acetate on the growth and survival of coliform and heterotrophic plate count...
Model Estimates of Nutrient Uptake by Red Spruce Respond to Soil Temperature
Mechanistic Modeling Imax Root Growth Rate Soil Buffer Power
2013/3/12
A better understanding of the mechanisms that control nutrient acquisition in the context of plant and ecosystem responses to climate change is needed. Mechanistic nutrient uptake models provide a mea...
Net Nutrient Uptake in the White River, Northwest Arkansas, Downstream of a Municipal Wastewater Treatment Plant
Streamflow Point-Source Pollution Nutrient Spiraling Source-Water Protection
2013/3/12
Wastewater treatment plays a crucial role in preserving water quality in receiving streams; however, continuous nutrient enrichment can diminish the retention capacity of rivers. The objectives of thi...
A laboratory feasibility study on a new electrokinetic nutrient injection pattern and bioremediation of phenanthrene in a clayey soil
Bioremediation Electrokinetic Ion injection Nutrients Phenanthrene
2013/12/12
Electrokinetic (EK) injection has recently been proposed to supply nutrients and electron acceptors inbioremediation of low permeable soils. However, effective pH control and uniform injection of inor...
