Transport of phosphorus in an alluvial gravel aquifer
(The Royal Society of New Zealand, 2015)
The transport of phosphorus (P) and bromide (Br) in an alluvial gravel aquifer was investigated in two tracing experiments: (1) injecting pulses of orthophosphate and (2) 10% diluted municipal effluent spiked with ...
Phosphorus transport in subsurface flow from a stony soil under irrigated and non-irrigated lucerne
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-07-29)
The extent of phosphorus (P) loss from soils under deep rooting crops such as lucerne is currently unknown. This study used large lysimeters (2.0 by 1.5 m) to quantify the amounts and forms of P in drainage under lucerne ...
The impact of cattle grazing and treading on soil properties and the transport of phosphorus, sediment and E. coli in surface runoff from grazed pasture
(Taylor & Francis on behalf of The Royal Society of New Zealand, 2021-04-21)
Contaminant loss from grazed pasture can negatively affect freshwater quality. There is, however, little data on the impact of different levels of grazing/treading on contaminant loss measured under field conditions. This ...
