Water chemistry under low-flow conditions from grazed pastures seeded with different species

This dataset contains water quality information of combined surface and subsurface runoff from hydrologically isolated fields under different pasture types at low hydrological flows. Different hydrological processes and a lack of dilution means that water chemistry at low flow may differ from at higher flows, but often the low flow means that automated in-situ measurements of water quality parameters is not possible. Presented here are data on pH, conductivity, nitrogen (nitrate, ammonium, nitrite, total nitrogen), phosphorus (total, soluble reactive, particulate), dissolved carbon, suspended sediment and faecal indicator organisms (E. coli, intestinal enterococci), measured in the laboratory. Also included are the automated in-situ measurements of some of these parameters, where the flow was sufficient to allow them to be taken.
